Here I am making a Octahedron. I made a 3D cube. I put markings on it to make it look like a dice. We made 3D nets as a hands on activity. While we were making them we could look at and identify how many edges, vertices, and faces each shape had.
We are counting all this money to find out how much we have. First we made small groups of $1. They could be - five 20 cents - two 50 cents - ten 10 cents - one $1 Then we added up each pile and found we had $25.
