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.

This book will have kids use their feet, paperclips and paper rulers to find lengths of drawings and real objects, putting comparisons and basic units before inches.

Learning numbers 1-10 is key in pre-math development, and this workbook teaches number recognition, counting and even simple addition with fun, bright illustrations.
