Addition and Subtraction, Multiplication and Division, Fractions and Decimals, Money, Patterns, Metric System, Perimeter, Transformations and Symmetry, and more! If you are home schooling (or if you are just trying to get extra practice for your child), then you already know that math workbooks and curriculum can be expensive. Home School Brew is trying to change that! We have teamed with teachers and parents to create books for prices parents can afford. We believe education shouldn't be expensive. Each topic of this book may also be purchased separately.
