Math Projects: Blocks

We used blocks and the document camera to talk about rectangles and triangles.

Someone noticed that one of the triangles had two long sides and one short side. We labeled the sides “L” for “long” and “S” for “short”. Then someone noticed the rectangle had two long sides and two short sides. Then we wanted to know “how long” because math girls always dig deeper and know exactly “how long” or “how short”. We used a measuring stick to find out the numbers and then wrote that down. We then traced the lines of the shapes. See how our math conversation continues:
