Beginnings
I am really excited to be starting our new unit. We just started our unit, Finding Out About the Past and we are going to be starting geometry to go along with it. Last unit I challenged my students to make a sphere using only 2D shapes. The spheres never worked out well because they kept collapsing in on themselves. For one group, I suggested using toothpicks instead. They got this far and I gave it to one student to take home and complete. That gave me an idea for geometry. I gave the students toothpicks and told them to make shapes. After they completed 2D shapes, I asked if they could turn it into a 3D shape. All the students started by making triangles. Then a few of them made square-based pyramids or triangular prisms. I asked them to make...
