The BLUE SERIES are worktexts with explanations in between the problems. In other words, the 'text' and the 'work' (=problems) alternate. These are perfect for those parents who have a weak math background. Also, with the worktexts one lesson spans several pages instead of just one page.
The worktexts have a blue cover.

The GOLDEN SERIES are grade level collections of worksheets: just one-page worksheets without any explanations. They are just math problems, like you'd find in a math book, one topic per page, especially designed for teachers - or parents - who wish to have worksheets to give for homework or to work at class, but who will provide the explanations and teaching themselves.
These grade-level worksheet collections have a golden / orange cover.

The GREEN SERIES are collections of worksheets by topic. They are one-page worksheets without any explanations, but concentrating on one topic per book. The books contain worksheets of various difficulty across several grade levels. These are perfect for teachers again.
These per topic worksheet collections have a green cover.

The LIGHTBLUE SERIES is a complete math curriculum. I currently have it available for grades 1, 2, 3, and 4. Each grade contains two worktexts, answer keys, and tests.

3. I am considering buying the Blue Series set for my first and fourth grader. Would this set cover the same information as the Golden Series grade-level sets or do the grade sets have other topics?

The grade level volumes are a later work and include some material from the topical ebooks. In particular, Grade 3 Worksheets Collection includes a lot of material from Multiplication 1, Division 1, and a few others.

Grade 4 includes some material from Place Value 3, Multiplication Division 2, and Geometry.

Grade 5 and 6 have a little bit of material from Fractions and Decimals and Geometry ebooks. But almost all of it is new.

Grades 7 and 8 (prealgebra and algebra) do not have any material from my other topical worktexts.

So yes, there is some overlapping. However, the grade level sets have a LOT of material that is not in the ebooks.

I realize that those who buy several books may find some material repeated, and that is one big reason why I have set up a volume discount:

Golden/Green Series package - $50 (download) or $55 (CD)
All Inclusive package - $91 (download) or $96 (CD)

This discount system should cover for the fact that occasionally some material is repeated, if you buy both the worksheets collections and the per-topic worktexts.

4. Would the combo pack of Blue, Golden and Green constitute a complete curriculum?

The Golden is NOT a complete curriculum since it's lacking the "text" or the explanations part. It is complete as far as the list of topics goes, but all it contains is problems. The same is true of Green.

The Blue is practically a complete curriculum for grades 1-3. It as quite a bit of material for grades 4 and 5 but it doesn't cover every single concept/topic for those two grades ( as of spring of 2008). This can change as I write more material.

5. Is the Blue series a complete curriculum?

As of this writing (March 2008), it is practically complete for grades 1-3. The only topic I can think of missing is ordinal numbers and Roman numerals. It will soon also become complete for 4th. I will be writing more material to it to make all 5th grade topics covered also; probably in the first half of 2009.

However, keep in mind several of the books in the Blue Series cover material for several grade levels in one book: Clock, Measuring 1, Money, Geometry 1, and Decimals 1. It is NOT organized exactly by grade levels.

6. Do the Blue and LightBlue have the same material?

Nearly so. There are a few minor differences, which will probably become even less as I write more material. Some of the differences in material are: The Blue Series Geometry 1 book and Fractions 1 and 2 books have material not included in the LightBlue grades 1-4. LightBlue 3rd has lessons on ordinal and Roman numbers. LightBlue Series has tests.

7. Are tests included in any of your books?

Yes, the LightBlue Series has tests, including placement tests.

8. How and where to order?

All the books on this website are available for *nearly instant download.
*Order processing at Kagi takes 1-2 hours; I do not know how quick it is at the other stores.

Most of them are also available as hardcopies.

9. Do all the workbooks come with answer keys?

Yes.

The BLUE series books have answers appended.

All of the GOLDEN series books, as well as most of the GREEN series books, have a separate answer key file. Some in the GREEN series books have answers appended.

The LIGHTBLUE series books' answer keys are included in the download or on the CD.

10. Can I buy the books as hardcopies (print versions)?

Yes. The BLUE and GOLDEN SERIES books are available as hardcopies (printed) through Lulu.com's storefront for Math Mammoth. The only drawback is that they are black-and-white and not full color. The full color publishing is fairly costly so to keep the prices lower, they are black-and-white (or grayscale).
