The first two books, Verbal Math Lesson One and Two, cover addition and subtraction of single and double-digit numbers, single-digit numbers multiplication, and division under 100.
This book, after a brief review, introduces two and three-digit addition and subtraction, multiplication and division of two-digit numbers by one-digit numbers, and basic fractions. It's all easier than it sounds!
We also briefly introduce concepts of rates and ratios, explain remainders (in division), teach about factors, and talk about the addition and subtraction of simple fractions. In each lesson, your child will apply basic mathematical patterns to solve everyday problems.
After this book, your child is ready for fractions.
