The worksheet serves as an introduction to using a ruler alongside estimation skills. It comes with a ruler cut-out, and at the top of the page, there's an example illustrating how to measure a pair of scissors. Students estimate the length of five classroom items and then use their ruler to measure them. Finally, students compare their findings by identifying the longest and shortest items. Use this worksheet to enhance lessons on measurement techniques and estimation accuracy.

This worksheet introduces foundational skills in measurement by guiding students through using a ruler and the estimation process. By cutting out and using the ruler provided, students learn how to measure items accurately, reinforcing the concept that estimation provides an approximate measurement, whereas a ruler gives precision.
