Full-color photographs show children counting coins, sorting Halloween candy, and other everyday events that relate to math. A few sentences of text per spread are balanced by colorful images. Sidebars marked “Think” offer word problems for readers to work out; an answer key is provided in the back matter. Glossary terms appear in a contrasting color font and are defined in the back with words and images. “Hints” and “Notes” offer more details such as suggesting rounding off prices to make it easier to estimate or explaining that squares are a special type of rectangle.
