1. Tiering Assignments: Rotating Review Activity

2. Quick! Grab a NET! What do you think of when I say the word What do you think of when I say the word “net?”

3. A MATHEMATICAL NET is a 2-dimensional model that can be folded to form a 3-dimensional figure.

4. Vertex: POINT where at least three edges meet Face: flat surface Edge: where two faces meet Vocabulary Reminders Polyhedron = 3-dimensional geometric figure having flat surfaces that meet along straight edges

5. Rotating Review Activity 1.Identify the NAME of each polyhedron at each station. 2.Analyze each polyhedron according to critical attributes … # of vertices # of vertices # of faces # of faces # of points # of points 3.Create an ANALOGY for each polyhedron 4.SKETCH the mathematical net

6. Matrix Graphic Organizer: Participants complete this as they rotate through the stations.
