Lesson objective: Understand that multiple objects can be measured and recorded to generate data.

This lesson helps to build procedural skills with measuring to the nearest whole number. A data table is used here because it allows students to record their measurements. This work develops students' understanding that we can generate measurement data by measuring several objects.

Students engage in Mathematical Practice 6 (Students will measure with precision using standard units in order to collect data sets) as they measure and record the length of their classmate's hand span.

**Key vocabulary:**

- centimeter
- data table
- hand span
- inch
- length
- measurement

**Special materials needed:**

- rulers
