With these worksheets children use their logical thinking to distinguish the difference between objects such as tall or short, more or less. Measuring helps kids understand the dimensions of objects.

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.

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.

Help your child master the idea of more, less, and equal. This workbook is filled with math comparison exercises that teach your preschooler the basic math concept of sizes and amounts.
