That’s useful! 😀

It helps to be married to a public school teacher. I’ve got the inside scoop. 😉

Mammoth Math is an excellent math program. I’ve always been impressed with how Maria Miller introduces concepts in so many different ways to ensure kids truly understand the mathematical principles.

Independence and self-teaching curricula are wonderful! Kids can get going on their learning without needing us to spoon-feed them. 🙂

Thanks for clarifying, Stephani! I’ve not paid much attention to Common Core, since it came out after I was settled into my homeschool routine. 🙂

Common Core is just a list of WHAT is to be taught/covered each year, not a HOW. The crummy Common Core math problems you see online have nothing to do with the Common Core sequence requirements, but rather with textbook companies scrambling to meet the new requirements and pushing out crummy textbooks.
Math Mammoth was not originally aligned with Common Core, but when the CC sequence came out, all Maria Miller had to do was to shift a few sections down a grade level to make it align (for instance “introducing” the concept of multiplication a year earlier). So, nothing in the teaching of HOW changed.

The sheet aligning Common Core to Mammoth Math merely lists the concepts needed to be taught at each grade and when Mammoth teaches the concept.

To be honest, I’m not familiar with how Common Core teaches, but I would say Mammoth Math teaches in a more traditional manner. A manner that is very conceptual. For instance when teaching children to add and subtract with carrying or borrowing, children are shown how to break apart the numbers. For instance 9 + 7 is switched to 9+1+6. Or 39 + 7 would be 39 + 1 + 6 = 40+6. Singapore Math, if I remember right, also teaches children to make groups of ten when adding. I saw this approach to teaching math long before I ever heard of Common Core. 🙂
