Explore early geometry concepts, such as two-dimensional shapes, and sorting and categorizing attributes.

There is a mix of objects in this workbook and it's up to your child to sort them by colors, shapes and sizes. Plus, he'll practice identifying weight and making simple comparisons.

A roll of the dice. A flip of a coin. A game of rock, paper, scissors. Kids are calculating probability all the time. The ability to predict outcomes based on the odds is the focus of this series.

This book takes preschool math to the next level with sorting practice, and then asks your child to figure out how many items are in each group – all through pictures of familiar animals and objects.
