One Foot Two Feet by Maloney & Zekauskas

Here’s an interesting mathematics concept book that might stand out from the others because it can serve multiple purposes.

A single object is introduced followed by a group. For example, a die-cut square frames a goose, but when you turn the page, there are 4 geese.

The page with the group of objects contains the actual cardinal number and 2 opportunities to count up to that number. Using the geese example, readers can count 4 geese and 4 eggs.

There is even an opportunity to count all of the objects shared and to introduce adding.

Language arts teachers might like the idea that while focusing on math concepts they can also help students practice recognizing and using irregular plural nouns such as mice and octopi.
