A robust preschool math curriculum will include instruction in all the five disciplines of math.

This includes teaching preschoolers within the measurement discipline, comparing weight, height and length, and learning about all the ways we measure in our daily lives.

Teaching within the measurement math discipline takes intentional planning.

During the preschool years, this typically focuses on comparing sizes and understanding measurable attributes.

For this activity, we used glass jewels to measure the vertical length of different-sized surfboards.

Students lined up each jewel on each surfboard and then counted the amount of jewels it took to reach the top.
