In art we discussed what a 3D shape was. Some kids began by describing 3D as a "pop-up shape". We went further in defining solid 3d shapes by defining it as an object that can be measured 3 ways; length, width, and depth.
My Monday 3rd Grade art class (Friedman) see me twice a week for the first quarter. One of those days is used to go further within the unit we are working. Today we learned about tetrahedrons. It's a solid shape made out of 4 equilateral triangles. Children traced 4 triangles as shown and created various tetrahedrons and begin taping them together to make a much more complicated shape solid.
