Sample Activities:

 

·        Students measure the width of their desks by counting how many widths of their hands it would take to go from one end of the desk to the other. They compare their results and discuss what would happen to the number of hands if the teacher's hand were used instead.

 

·        Students read and discuss How Big Is a Foot? by Rolf Myllar. The king wishes to give the queen a special bed for her birthday and measures the size using his own foot. He gives the measurements to the carpenter, who gives them to the little apprentice. The bed that he makes is too small, but the apprentice solves the problem and everyone lives happily ever after. The students use their own feet to measure the width or length of the hallway and compare their results. Finally, they measure the hallway using meter sticks.

 

·        As an assessment of the students' understanding of units, the teacher has the students measure the length of their math book using paper clips, unifix cubes, and yellow Cuisenaire Rods. They write about their results and explain why they are different.
