Math Mammoth Grade 1 aligned to the Common Core Standards

Math Mammoth Grade 1 Complete Curriculum is now aligned to the Common Core Standards.

Here is a document listing the lessons and the corresponding standards.

I will record here the main changes in its content as compared to the earlier edition / version (through April 2012).

You can tell the new edition and the earlier ones apart by their cover image: the edition aligned to the Common Core Standards has these new cover images.


What used to be chapter 4 (Place Value) switched places with Chapter 3 (Addition and Subtraction Facts within 0-18). 

The topics of rounding, even & odd numbers, and parenthesis were taken off as they are  not in the Common Core standards for grade 1.

There are many new lessons about adding and subtracting within 20, and adding and subtracting two-digit numbers without regrouping, explaining basic  mental math principles.

The lesson "Exploring Measuring" is split into two lessons (Measuring Length and Exploring Measuring). Both lessons are expanded from what they were before.

Geometry section was expanded and changed. It now has more material about shapes.

Hi! I purchased the whole set of grades 1-6 for my family. Is there a way to get the new editions without paying full price again?

Yes, there is. If you purchased at Currclick, just redownload it from your account. If at Kagi, you need to contact me.

What about through Homeschool Buyers Co-Op?

If you bought it at the Co-op, you could wait till I get all the grades aligned and then I plan to contact everyone and send them an update. If you need it right now, please email me.
