Help Me Learn Subtraction

This book is aligned with the Common Core State Standards for kindergarten and first grade in mathematics in operations and algebraic thinking (K.OA and 1.OA). Photographs of toy dinosaurs, monsters, piglets, and other objects; rhyming text; and a game help children learn that subtraction is a take-away action! Rows of colorful rubber duckies show subtraction facts. Hummingbirds and chickadees show the difference between addition and subtraction in this entertaining introduction to mathematics.
