How do you teach students the difference between metric and customary units of measurement? One of the activities I use is the graphic organizer shown below.
I find that having students see the whole picture of what we want them to learn in measurement is important. I would begin by filling in the chart together. I have used this as a scavenger hunt with food packages either in class or as homework. To download the Unit of Measurement chart, please visit this post at Artistry of Education.
