Tiering Assignments: Rotating Review Activity

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?”

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

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

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

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