1. Math Mammoth news

You may already know... there will be a new edition of Math Mammoth grade 3, hopefully in the beginning of summer. Here are some example pages. 🙂

I have included a thorough section on mental math in the first chapter, especially designed to those who come to MM from using some other curriculum. Geometry chapter is pretty much rewritten. And there are various other changes, as is usual in a revision process.


2. Leap day and other calendar oddities

This year is a leap year, so, February 29 will be a LEAP DAY — an extra day added to our calendar every four years (well... almost every four years).

It is a nice opportunity to talk to children about this peculiar day, why it exists, and the math behind it.

Maths Is Fun website has a simple explanation and an interesting graphic worth peeking at concerning leap years:

And if you'd like to learn more about various calendar oddities, check out: Leap Year and Other Calendar Oddities

For example, did you know some people have proposed calendar reforms that would employ a 364-day year? 😃

3. Principle 4: Living and Loving Math

Continuing our series... this is the last piece, featuring one more habit or basic principle of effective math teaching. 😃

teaching children to cook You are the teacher. You show the way — also with your attitudes, your way of life.

Do you use math often in your daily life? Is using mathematical reasoning, numbers, measurements, etc. a natural thing to you every day?

And then: do you like math? Love it? Are you happy to teach it? Enthusiastic?

Both of these tend to show up in how you teach, but especially so in a homeschooling enviroment, because at home you're teaching your kids a way of life, and whether math is a natural part of it or not.

Math should not be a drudgery, nor something just confined to math lessons! It is said to be the "science of patterns". Just think how MUCH that definition actually includes!

Some ideas: shopping
  • Let it make sense. This alone can usually make quite a difference in making children to stay interested.
  • When you use math in your daily life, explain how you're doing it, and include the children if possible. Figure it out together.
  • Use fun math books, such as
  • Try including a bit about math history. If you're interested in math history, check out Living Math for lesson plans for a family math history course.
At any rate, I wish you very happy math teaching and learning!

4. Puzzle Corner was too easy!

One of my customers mentioned that this particular puzzle corner from Math Mammoth Grade 1-A was too easy for her son:

Math puzzles for 1st grade

I admit, it's kind of easy. But, like I told her, I'm sure some children enjoy having an easier puzzle corner in between the others because several people have mentioned they are challenging to their children.

But, you can make it to be more challenging very easily: simply add a number to each equation... and possibly also make (some of) the numbers bigger. For example:

− 4 = 5

Change it to:
− 4 − 2 = 5
5 − = 4

Change it to:
10 − 5 − = 4
+ 4 = 5

Change it to:
2 + + 4 = 11

And similarly the others. He can even enjoy the challenge of changing the problems himself... and then solving them!
