The student uses nonstandard units to describe length, weight, and capacity. Using paper clips, they imprint them along the length of the snake. They count the imprints to measure the length of their snake.
Students compare their estimate with their actual measurement.
Each student makes a snake of play dough or clay. They record their estimate and final measurement in some way that makes sense to them. The student uses nonstandard units to describe length, weight, and capacity. This time the students estimate and measure first using small paper clips and then again using large paper clips. Students discuss the results.
