Benchmark Numbers - Decimals

Benchmark Numbers is a hard concept for my students. However, I figured out a way that made my students understand it.  First, I decided to get my students out of their desks. I took masking tape and made a number line on the floor in the back of my room. I labeled 0, 0.50, and 1 on the number line. Then, the students wrote down different decimal numbers and they had to place it on the number line with no help from me. They had to discuss it in their group and figure it out. It was great. One of the best lessons I've taught.
