Math Mammoth Percent

Math Mammoth Percent book is here! Part of the "Math Mammoth Blue Series", this is a topical worktext, which contains both the instruction and the exercises in the same book. Download price: $3.50.

I know that the concept of percent and related applications are often difficult for students. I wrote this text keeping this in mind, and I hope it can clear the confusion on percentages, percent of change, and such topics!

From the description:

Math Mammoth Percent teaches students the concept of percent, percentage of a number, discounts, sales tax, percent of change, circle graphs, and percent of comparison. It is suitable for 6th-8th grade (middle school).

The concept of percent builds on a student's understanding of fractions and decimals. Specifically, students should already be very familiar with the idea of finding a fractional part of a whole (such as finding 3/4 of $240). Students who have used Math Mammoth have been practicing that concept since 4th grade, and one reason why I have emphasized finding a fractional part of a whole so much in the division and fraction materials in the earlier grades is specifically to lay a groundwork for the concept of percent.

Assuming the student has mastered how to find a fractional part of a whole, and can easily convert fractions to decimals, studying percents in middle school should not be difficult.
