This is a fun and easy activity for teaching measurement with non-standard units.
I get my students to measure a partner with adding machine tape (your secretary probably has a lot of it because it isn't used in the office anymore) and to cut the adding machine tape to the length of their partner. I get them to use the adding machine tape so they don't have to lay on the ground for a long period of time. Then they glue one of these strips onto their adding machine tape and they measure and compare each others heights with their partner with these non-standard units. In the box next to the object, they write how many of that specific object they needed to measure the full body length. Be sure to talk about the objects touching versus placing them along the paper with gaps between them and how it can significantly change the answer.
As they finish, we put them on the wall from tallest to smallest or smallest to tallest.
Every year I do this activity my students love it. I've done it with K, Gr.1 and Gr. 2. :)
