Inchworm Measurements–Measuring with Non-Standard Units

Yesterday we did the Elephant Measurement and had “such enormous fun” that we called for another non-standard measurement unit to come play…so today we are doing Inchworm Measurement (clever aye?)!

This fun activity of measuring with non-standard units will help your child understand the attribute of length, develop a process of measuring, understand concepts related to units of measure, use estimating to measure, and learn how to use these processes in everyday life.
