Have students find an object that is shorter or longer than 1 foot length in the classroom. Have them use
their feet to measure it.
Then have them find an object that is shorter or longer than the length of their hands.
After students realize the need to use smaller units than the size of their feet, they will learn about inches.
For now, have students use the length of their hands to measure smaller objects.
