Math Mammoth Light Blue Series

Math Mammoth Light Blue Series constitutes a full elementary mathematics curriculum for grades 1-7A.

Some of the main features of the curriculum are:

  • It is mastery oriented, concentrating fairly long on one topic, with fairly few topics per grade;
  • It focuses on conceptual understanding.
  • Visual models and exercises are used a lot.
  • Mental math and number sense are emphasized.
  • The curriculum is nearly self-teaching for many children, since the explanations of concepts are found in the student worktext. Thus it requires fairly little preparation time from the teacher.
  • The curriculum meets and exceeds the Common Core Standards.


What is provided?

Each grade level in the curriculum consists of two student worktexts (A and B) which contain both the teaching (explanations) and all the student work (exercises), answer keys, tests, cumulative review lessons, and a versatile worksheet maker (Internet access required). The curriculum meets and exceeds the Common Core Standards.

Additionally, the download and CD versions provide these "extras":

  • files to replace the chapter on money in grades 1, 2, and 3 in Canadian, British, European, Australian, and South African currencies. The student worktexts use U.S. dollars as a default currency.
  • bonus software Soft-Pak
  • user guide (available also for free download on the web page of each grade level)
  • documentation for Common Core alignment (available also for free download on the web page of each grade level)

You can read more details at the Frequently Asked Questions and Answers page.

Placement

It is fairly important that you have your student(s) take a placement test or several prior to introducing the student to Math Mammoth. Many popular math curricula are easier than Math Mammoth and thus there is a danger the child is placed too high, if you simply follow the "grade level" from the child's previous math curriculum.

If you'd like, you can send the placement test results to me, and I will personally review them and suggest a course of action.


Purchasing

I do not personally sell anything on this website, but use several resellers (Kagi, Currclick, Lulu, Rainbow Resource Center).

  1. The download versions are available in two places:

  2. CD - you can purchase each grade level on a CD, or a bundle of all six grade levels on a CD. These are available at Kagi and at Rainbow Resource Center.

  3. Printed versions are available at Rainbow Resource Center and at Lulu. Please see links to those stores in the pages for the individual grade levels.

The PDF files in the download or CD are enabled for annotating. This means that the student can actually complete the PDF file on the computer, using the typewriter and drawing tools available in Acrobat Reader version 9 or higher, or on a tablet device such as an iPad, using a PDF app that has annotating tools.

It is also possible to buy either A or B part (half) of any grade (download only). Discounted bundles and CDs are available for all six grades, for grades 1-3, or for grades 4-7A.

*BONUS*: If you buy the Light Blue series products on a CD, or in Kagi store as downloads, you will also get Soft-Pak elementary math & language arts programs completely free.

The video below explains the basics of the Light Blue series curriculum.


The old version

The ORIGINAL (old) version before the major revision and CCS alignment that I completed in 2012-2013 is also available:


Customer feedback/reviews

Besides the reviews from customers (below), you can also read Comparisons between Math Mammoth and other popular homeschool math curricula.

Hi Maria,
I purchased your math curriculum 3 years ago. Let me say, "Thank you!" I have really enjoyed using your materials and my daughters are doing so well. I love the way the material allows them to work independently and to think mathematically. Their standardized test scores consistently put them in the top percent. This curriculum has been a great tool for our homeschooling, and I am so thankful for it. My oldest daughter is entering 4th grade but will be working through grade 5 math (the beauty of home schooling allowing us to work at the level they are ready for!). I've already started wondering what I’ll do when she completes the grade 6 curriculum but just saw on your website that you're working on materials for grade 7. Excellent!

Thanks again for all your hard work in creating excellent math curriculum!

Hi, Maria

I just want to send you a note that I absolutely love your curriculum! I think it's the best available. It's rigorous, yet the lessons start very basic and are colorful and engaging. I also love how many different ways you explain and have the student practice a concept. I'm waiting with baited breath for your seventh grade curriculum!

Sincerely,

Maria,
I would like to thank you for Math Mammoth. Your curriculum has done wonders for my daughter who struggled with math. We took 6 months off from math in the second grade because she would be in tears every time we worked on math. She was frustrated and so was I because I could not figure out how to explain concepts to my child and I discovered that she really had little understanding of the math we had already covered up to that point. I searched for a more suitable curriculum and tried out two other curricula before hearing of Math Mammoth on a homeschool forum I participate in. I decided to give it a try since your sale made it so affordable. I am so glad I did! My daughter worked hard and did two and a half or three workbooks of the Light Blue curriculum per year for a few years. Her hard work has paid off. She has gone from being a grade behind when she started using your curriculum in second grade to now being ready for pre-algebra or quite possibly even algebra, at the end of seventh grade. I don't know how often you get emails like this, but I had to let you know what a difference you have made for my daughter. She understands math now! It may never be her favorite subject, but at least now, after finishing Math Mammoth, she has confidence in her math abilities.

My son switched to Math Mammoth this year from Teaching Textbooks. He had completed Teaching Textbooks 6, but we had to start back with Math Mammoth 5 when we switched. That tells you how far behind TT is. My son loved TT, but even a non-math person like me could see that TT was not giving him any practice in mathematical reasoning. He was getting A's on every lesson and test, but if I gave him a problem that was worded differently, or one that required him to do something even slightly complex with the information he had learned - he was stumped. It took him a few weeks to adjust to the much more rigorous work in MM, but after finishing the first half of level 5, he is doing very well - often understanding concepts and figuring out problems way before I do. And I am learning a lot too - grade 5 is just about where I got lost in math and I never got found. I wish I had had Math Mammoth!

Thanks Maria

I would like to say thank you to you for the wonderful curriculum you have designed. I appreciate all the work you have put into it. My daughter started off math with another program (and she absolutely hated math). We were using some of your sheets as supplements, and both felt that your program was superior to the one we started with. I love your creativity and how you approach concepts from a number of different angles. The color sheets, as expensive as they are to print, have helped my daughter as well. Now, while math is still not her favorite subject, and probably never will be, we have far fewer complaints about the topic -- she has even had moments where she said she loves math. All in all, she is happier, and I feel that she is learning so much more. Thank you!

Thanks so much for your math curriculum - there are so many beautiful things in the way that you've structured your work. It does so many things that I always wished a curriculum did. I also appreciate that you use basic math terms that are common to the discipline; this helps tremendously helping kids prepare for our state assessment. Because all of the instructions are with the worktexts, my children's parents know how to help and support at home - that's so appreciated because it builds the home-school partnership. I want math to be accessible to both my parents and their children, and your work helps to facilitate that process of working together to learn math. Thanks for your thoughtful and thorough work - I know it's making a positive difference for my students!

Love this program! The details of how to find the mathematical answers are clear, the pages are uncluttered, and their customer service is not only very friendly but quick too. What else do you need from an educational tool?!

II want to tell you that we love Math Mammoth! Thank you for creating such a smart curriculum. I've tried several. This is especially great for a mom who also has to work or has several kids. It has been a great success for my 13 year old son. He has been in our family only 1 year, adopted from China at age 12. He is very behind in everything, but LOVES Math Mammoth and is being very successful. My daughter, who is in her appropriate grade, also enjoys it. I am telling my friends about it, trust me!!! It starts a kid out right, working independently at their own pace with a teacher being more of a tutor. This is so much better than them being spoon-fed a script. I also like that it doesn't have a lot of different pieces. Sometimes I bring out a manipulative to help a child with a concept, but I'm thankful I'm not spending a lot of time cutting out little paper clocks, triangles, etc. How I WISH I had it when my other 13 year old was starting out. I started her in Abeka in which she was successful but I despised. Then we moved to Saxon which I loved and SHE despised! Then we moved to Right $tart Math, and, oh my, do not get me started!! We finally pitched that and in grade 9 she's chosen to use Saxon and is happy with it. Sadly, because of all the changes and experimenting, she is behind, though she is very bright. Oh well.....

I purchased Math Mammoth for my 3rd grade daughter and used in conjunction with her math studies at school; great improvement in her math due to her completion of all of the Math Mammoth exercises. I am ordering the 4th grade series. Wonderful series!

I wanted to make mention that my children were recently given a standardized test to fulfill our state's homeschooling regulations. The score on their mathematical calculations were slightly above grade level, but their score on "mental" math was several grades above grade level. I attribute this entirely to your program: the thorough teaching and emphasis on "mental math" is well worth it. As a bonus, my children enjoy it (they much prefer your program to Math-U-See, which we used briefly). Before the test, I was a Math Mammoth devotee and suggested the program to most anyone who asked. How much more so now!

Dear Maria,

I wanted to thank you both for developing the Math Mammoth resources and for your helpful blog entries. I subscribe to your blog and in March purchased the full set of Light Blue series resources through Kagi. My children, ages 6 and 7, find your workbooks to be challenging, fun, and engaging. My 7 year old especially enjoys the Puzzle Corners.

We also use the included internet resources and suggested games on a weekly basis. My kids now look forward to math time. It is obvious that you have a passion for math and for children. Thank you for investing the time to develop such high quality materials and for your continued effort to share your passion for math with parents and children through your blog.

Sincerely,

Hi, just sending you a note to say how much we are enjoying Math Mammoth. I started homeschooling this year, with Math U See, and have switched mid year to your program and thank goodness I did. The kids - 2 of them - are doing really well with your program. Unfortunately I had to put my grade 2 daughter back to the grade 1 level, but she is breezing through what she knows and just filling in gaps, so it's no trouble at all.
Thanks again for such a gentle, natural math program!

I'm a homeschooler & my two kids have been in public school until March of this year. I have tested them and my 1st grader made a 37 while my 2nd grader made a 57. Public school had my kids as straight A students and had told me that both had test out for the year so no worries on them moving up!! I am having them repeat 1st & 2nd grade math obviously & I gave them the option of what they wanted to learn first.

My 1st grader picked double digit math so we started learning place value today. He absolutely loved the virtual abacus!! We also had an ah ha moment. He now understands what the tens place is & what it represents. It is so nice to see that lightbulb go off!! As for my daughter, well she picked geometry & fractions and completely lived today's lesson & got very excited when she saw her A+ in the geometry picture once colored. Excellent added bonus for her. Just joined a local group & will be discussing your stuff for sure!! Thanks so much. Great product.

Dear Maria,

I wanted to tell you what a wonderful success MM has been for us. I have now used it with our 3 youngest children. The older 2 started with Horizons. I purchased Math Mammoth to use just with our youngest, who is now 7, but when I saw how much it made sense, I had the other 2 switch to it as well. My 10-year-old is now working on long division, and something about how you explain it made it so much easier than Horizons ever was for the oldest 3 children, which I still consider pretty good. For my 7-year-old, he just gets it so very well. Your explanations are wonderful, and he can already add and subtract large numbers in his head, which is awesome. Thanks so much!

Best regards,

P.S. I have recommended MM on my blog and will be doing so again soon.

I'm usually a quiet user of curriculum which means I rarely let publishers know my likes and dislikes. Also, I'm a curriculum junky! Between my three children I have used so many different math curriculums that I've lost track. I'm saying all of this to tell you .... I LOVE MAMMOTH MATH! As a prior elementary teacher and now a homeschool mom for 7 years, even I am learning new ways to look at math and problem solving. I am so thankful I accidentally found Mammoth Math. Thank you!

Hi Maria,
I just wanted to let you know that I homeschooled my son for math for the first time using strictly your curriculum with only a supplemental practice in a few places. On the NWEA he scored at the 98th percentile for 6th grade (he is in 4th grade)! Thank you for your approach and focus on problem solving and skill mastery! I will not use anything else.

Dear Maria,

We tried the samples with our oldest (of three children) and liked them so much that we purchased the grades 1-3 bundle on Currclick.

It's hard to know where to begin with thanking you. Your website, blog, and videos are rich resources. The samples alone would have been a great help. The seven-day tour is a great idea. I'm really impressed with all that you offer to parents and teachers.

I love the format. No more juggling a bulky Teacher Manual or making copies or complicated planning. My oldest is only six, so I sit with her, but the format of Math Mammoth really eases the organization and planning. She enjoys being able to read the lesson and do as much as she can with me close by to help.

You have given us a wonderful resource. Thank you again.

Sincerely,
Sarah

I have tried a couple of the blue series worktexts and my children and I loved them. We have struggled to find a good math curriculum that suits our learning styles, teaching styles, and budget and I feel like after sampling several math mammoth worksheets and worktexts, it is the perfect fit for our family. Thank you Maria for answering all of my questions when I emailed you and for writing such a parent and kid friendly curriculum that is aligned with common core standards!

Just want to thank you for Math Mammoth! Very affordable. I have thrown everything else out and this is all we are using. My math-hating daughter who just finished third grade is doing the multiplication from the blue series to prepare for 4th grade next year. She is doing this on her own over the summer because she likes it! Never thought I'd see that. She has really struggled with multiplication and she says this is making it so much easier for her to understand. I love the ability to use the blue series to fill in the gaps of what they don't "get" the first time around. This is so customizable for different kids. I love the pdf format also. I can put the book together in any order I want. I love the no teacher's manual thing. With three kids it is hard to shuffle around 3 books. This is so much better because when each kid has questions they already have it all with them when they bring it to me. I was so excited to find this. Wish I had found it a couple of years ago! Thank you for this curriculum and thank you for making it affordable. I bought all 6 levels at once. I could never afford to do that with any other curriculum. This has ended the struggle (for the most part) with my daughter. Thank you for making teaching my kids math affordable, easy, and even enjoyable!

Hi, Maria! I just wanted to thank you for your math curriculum! My 7 year old son was struggling with math using a different, rather more expensive curriculum, so I took a crazy chance on Math Mammoth after remembering your blogging about it. Just a few weeks into the second grade books, and he's having no trouble at all! He doesn't cry during math anymore. I am so very relieved that I just had to tell you. Thank you for your no-nonsense, easy-to-understand approach to math.

Hi Maria...I just recently purchased Math Mammoth for my 3 children... here are the things I've been hearing in my house for the first time:

"Mommy, this is fun!"
"Mommy, can we do math first today?"

I'm enjoying teaching the math...and the girls are already feeling more independent (the two who are reading well, anyway)...sometimes needing a bit of clarification. I think they're carrying themselves a bit more confidently these days as well.

Thank you!

I LOVE this curriculum. I have 7 children and you make it affordable to homeschool... they can do their math pretty independently... and best of all... my kids all "get it"! Thanks! I am even learning how to do my fractions!

Dear Maria,
I pulled my 2 daughters out of public school to teach them at home. Now, this was a very difficult decision for me as it is for a lot of parents. I am not always confident that I am teaching them as well as a school teacher would. I also work full time and teach them by myself as a single parent.

Finding a thorough math curriculum was at the top of my priority list. I needed something that I could easily explain and that they would quickly learn. Math Mammoth has been the perfect Math source. It has given my youngest daughter the confidence in learning that she was not getting in public school. After getting used to the instructions given in the books, she practically teaches herself with the Light Blue series. I come home from work, check her lessons for the day, and usually find that she has completed them on her own with very few errors, if any at all! It has made our afternoon/evenings much more enjoyable.

In using the Math Mammoth books, I have become more confident that my daughters will succeed in all areas of Math.

Thank you,
Darlene Brown

Maria, I have your complete set... I can't tell you how much I've enjoyed using your math lessons in my special ed classes... You have done a terrific job, my students love as do I... I encourage everyone to at least try the sample and I promise you will want to purchase it... Thank you for everything!

My children are learning SO much from your teaching style. I LOVE the way you teach different ways to look at the problems, so that it is not rote, but conveys more the intricacies of playing with numbers. I backtracked when starting with Math Mammoth to make sure our two boys had a strong foundation, and I'm glad I did. (4th grader doing 3rd grade worktext, 2nd grader doing 1st grade worktext)

Again, I thank you for this wonderful resource!

Dear Maria Miller,
My daughter had been struggling with Singapore Math in 3rd grade and had disappointing scores on her standardized test at the end of the school year, so last year we switched to Math Mammoth for 4th grade. She understood and enjoyed math again, and she had much higher scores on this year's test! She has renewed confidence in her ability and is eager to do her math lessons every day. There was no question in my mind about ordering Math Mammoth for 5th grade this year. Thank you so much!

I am a Canadian homeschooling mum of four living in Switzerland. My school age children are 11, 9 and 6. My preschooler is 2 1/2. I absolutely adore the complete curriculum series. I am currently using grades 1 and 4. My six year old flies through the pages asking if he can do just one more most days. I suspect that he will be on the grade 2 books by Easter at this rate. Prior the starting the grade one curriculum, he attended a Montessori school. His passion for numbers may be inborn for but this was not the case for his older brother or sister and they enjoy the work as well!

Last year I decided to homeschool our 10 year old son. He is bright outgoing and articulate but he had lost his spark for learning. As there was no complete curriculum available for 5th grade I used the fourth grade one and supplemented with the green and golden materials for 5th grade. Within a few weeks, he stopped groaning about math and began to genuinely look forward to the work. Words cannot express how pleased I am that he has found a love of numbers again. I found it very, VERY challenging to choose a program for him this year but settled on YourTeacher.com pre-algebra which I supplement with gold and green grade 6 materials.

Our 9 year old daughter has never found math easy or interesting but I hope to see that change as we embarked on a homeschooling journey with her this year as well. She is diligently working her way through the complete curriculum for fourth grade and when she finds that too daunting, I print something from the third grade books to refresh her memory. I don't expect her to look forward to her daily math lesson BUT she no loknger dreads it and we are only 7 weeks into the year.

My communications with you have far exceeded my expectations. You answered my emails promptly when I was begging for a 5th grade curriculum in February 2008 and I am so pleased to see that it is now available. Well done!

There was a time when I lost all of my data because of a hard-drive malfunction and this meant that I no longer had access to the Math Mammoth materials. I was about to re-order when I thought that it might be worth asking if it might be possible to have them re-sent. They were in my inbox within hours.

We also own the clock and multiplication book which are being used by our 6 and nine year olds respectively. They are thorough and progress in a slow and steady manner that makes learning these tricky concepts easy.

I always look forward to reading your latest articles about teaching math. I do not have a true passion for numbers myself but I am thankful for the math teachers in my life who did. It is thanks to them that I never struggled with the concepts. From your articles, it is clear that you are one of those teachers and I am grateful to have stumbled upon your website.

Thank you so much for all that you do to instill a love of math in children!

Respectfully,
Denise
