Subtract It!: Fun with Subtraction

(3) K-3 Math Beginnings series. These six colorfully designed books, heavily illustrated with stock photos, contain short chapters introducing math concepts (addition, subtraction, counting); tools (rulers, scales); notations (plus, minus, cent sign); equivalents (coins to dollar bills); and more. The user-friendly books feature large print and real-life examples. Most chapters end with a hands-on activity or question to extend concept learning. An additional activity concludes each book.
