### Math Anchor Charts- Geometry

The above anchor chart is on classifying quadrilaterals. It is important for students to understand that there is more than one way to classify a quadrilateral. For example, a square is a quadrilateral because it has four sides and four angles. It is also a parallelogram because it has two pair of parallel sides. It is a rhombus because it has four right angles, two pair of parallel sides, and 4 sides of equal length. It can also be a rectangle. So, a square is a quadrilateral, parallelogram, rectangle, rhombus, and a square.

This anchor chart is on how to graph using the coordinate system. The students learned to graph ordered pairs by "running" down the x axis, and "jumping" up the y axis. You always have to run, then jump!
This anchor chart is on solid figures. Students need to be able to identify the number of faces, edges, and vertices in each figure. They should also be able to identify a figure by looking at a net. A net is the figure unfolded, as shown on the left hand side.
