Math Mammoth Percent book updated

Math Mammoth Percent is a worktext (with both instruction & exercises) that teaches students the concept of percent, how to calculate the percentage of a number, to figure discounts, sales tax, and interest, to draw circle graphs, to differentiate between a percent of change and a percent of comparison, and to know how to calculate both.

The text is suitable for grades 6 through 8 (middle school).

This book has been now updated to include many new lessons that will ALSO be in the upcoming Math Mammoth grade 7-B. This means that you can use it to continue pre-algebra studies after 7-A.

Or even simpler:

"2 and how many more makes 3?"

Objects can also be used.

This lesson, "Missing Items," is fairly early in 1-A. You can start with MM 1-A, and if this particular lesson …

New review of Math Mammoth

I just got word about a new review of Math Mammoth, from Kate's Homeschool Math Help. The owner, Kate, has written helpful reviews and buying guides for Math Mammoth, Singapore Math, and RightStart Math. She also has lots of other tips for teaching math or choosing a homeschool math curriculum on her site.

Kate says, "I'm a math educator turned homeschool mom. My mission is to help homeschool parents hone their teaching skills and teach math with confidence."

Calculating Pi with Real Pies

This is a neat video, showing how to calculate the value of Pi using real pies (yum!). It might help your youngsters remember the definition of Pi better as they remember the visual pic of pies around the big circle and pies going across. :)

Remember also that Pi day (3/14) is upon us soon...
