Math+Talk

This video is the preliminary talk about area on Day 1 of my unit. In it, my students discuss what they already know about area, discuss ways to find the area of shapes, and discuss whether or not they are finding exact answers or estimates. They began to realize that some of their shapes that they initially perceived as estimates, could be exact answers. I had a handful of students count half squares and use their previous knowledge of fractions to figure out exact answers. As this video ended, I asked them to come up with a definition for area. After most children shared their definitions, they ended up using a combination and created the definition, "Area is the amount of space inside an object." They added this definition to their math journals, and I added it to our math wall.
