## Lesson: Measurement

Developing the Concept

In this lesson, the students will work with Customary and Metric units of weight, capacity and temperature.

**Materials:** balance, 16 1-oz weights, 1-lb weight, a 1-cup measure, a 1-pt container, a 1-qt container, a 1-gal container, a 1-L container, a dropper, water, 1-lb object (box of raisins, rice, brown sugar, or soup can), picture of an American bison; and a copy of Worksheet A (PDF file) and the Weights and Measures (PDF file) worksheet.

**Prerequisite Skills and Concepts:** Students should be familiar with both customary and metric units of weight/mass, and capacity.

**Wrap-Up and Assessment Hints**

Use the Weights and Measures (PDF file) worksheet to assess students' understanding of metric and customary units of weight and capacity. Answers are annotated on the teacher version (PDF file) of the worksheet.

Give students a copy of the weather page from a local newspaper or find a copy of an Internet weather page with both Fahrenheit and Celsius temperatures. Have them use their "thermometers" to find the difference between high and low daily temperatures. Using international temperatures will provide a wider array of numbers and help students gain practice with negative temperatures.
