10. Math Topic: Measurement
...to figure out if you are taller than someone else? Or have you ever put your hand up to your parents' hand to see how much bigger their hand is to yours. Well if you have done one of these then you have worked with measurements. Today we are going to use nonstandard measurements to explore out body ratios. Now let's discuss what measurement is exactly. Also we will review what a ratio is so that we will know what I mean by our body ratios. Here I will work with the students to let them come up with a definition of measure and then quickly review ratios and estimation. Development of the Mathematics C...
