We're still in our 3D Geometry / Measurement unit, and we added 2 more entries to our math journals this week. We made a foldable triangular prism, and a tetrahedron (square-based pyramid). We wrote the attributes inside the net, and then solved for the volume and surface area. We've also been adding to our 3D Shapes anchor chart. Come on over to my blog and see our math journals from this week. While you're visiting, I would love to hear if and how you are using math journals in your classroom.
