Lesson objective: Practice measuring length and height using non-standard measurement tools.

This lesson helps to build procedural skills for measuring with a non-standard measurement tool. Showing the procedure of measurement (with paper clips) is used here because it highlights the importance of measuring with precision. This work develops students' understanding that objects can be compared based on an attribute they share.

Students engage in Mathematical Practice 5 (Use appropriate tools strategically) as they learn and practice the procedure of accurate measurement using non-standard tools.

**Key vocabulary:**

**Special materials needed:**

- paper clips
- bear counters
- cubes or other non-standard measurement tool
