chinese skipping ropes and geoboard and block
By cindyteacher

1) You can use the geoboard and have them make the polygons. They can sit with partners or in small groups and compare the many ways an octagon can look. Use this time to talk about regular octagons etc. and irregular octagons
etc. The kids find it exciting when they end up making the same one and when they end up making different ones. Regular polygons are more difficult to make then they think. The record them on square dot paper.

2) Along the same lines, you can use chinese skipping ropes (basically really long elastic bands-used for jumping). YOu can usually buy them at the dollar store (usually

in the seasonal section). Have the students work in groups and make the polygons (their legs act as the vertices). So they stand inside them and each person acts as a vertice).

3) Use the pattern blocks and have them find the many combinations of pattern blocks that are congruent to the yellow hexagon. For example, 6 green triangles are congruent, 3 rhombuses, 1 rhombus and 4 triangles, 2 trapezoids, etc. They can record the combinations on a paper of 8 hexagons.

4) They can make pet pyramids or pet prisms. They can use plasticine and construct a pet and then describe the pet using its vertices, edges and faces/bases

Have fun! My kids loved geometry!
