# Explore metric units of measure by comparing centimeters and meters

Big Ideas: Metric measurements can be compared by their relative values. The lesson builds on students' work with measuring using standard units. This task presents students with a scavenger hunt in the classroom to find items that are about 1 centimeter cube or 100 centimeter cubes long. Students create a meter stick to help them with their hunt. Afterwards these tools are related to units on standard measurement tools: rulers and meter sticks. The mathematical concepts in this lesson build toward students' future work with the number line and finding sums and differences within 100. Vocabulary: about, longer, shorter, measure, standards units, units, metric, tools, ruler, meter, centimeter, ruler, meter stick, measuring tape, estimate Special Materials: Centimeter cubes centimeter grid paper Ruler Meter stick Measuring tape tape scissors
