### Math Mammoth Grade 4 aligned to the Common Core Standards

So, Math Mammoth Grade 4 is now aligned to the Common Core Standards. I will mention here some of the main changes as compared to the previous edition.

The main changes in the revised edition of Grade 4 are that some topics were taken off and moved to 5th grade, and several topics were added in. Again, this is all due to the CCS. Other than that, the basic framework and conceptual development did not change substantially. Of course, I edited the lessons to make them better, added more space or grids for calculations, etc. so there were many cosmetic changes.

**Topics moving to 5th grade:**- Numbers beyond 1,000,000
- multiplying a 3-digit number by a 2-digit number
- 2-digit divisor in long division
- multiplying decimals by whole numbers
- circles
- volume
- In measuring, the problems about conversions between units are easier, and the more challenging conversions will be in 5th grade.

**Topics added that weren't in 4th grade before:**- divisibility
- prime numbers
- finding factors of a given number
- multiplying fractions by whole numbers
- adding a fraction with tenths and another with hundredths (such as 3/10 + 8/100)
- Line symmetry

Is there anything that moved down a grade?Meaning, introduced earlier than you had previously introduced it? I love the MM program because it is relatively easy, and still comprehensive. I was worried that we might be missing out on something, but after reading how many things moved up a grade, I'm starting to think the old version might just be the "advanced" version, not the "old" version! ~Ginger
