Create as many different triangles as possible on a geoboard. Record the different (non-congruent) triangles on grid paper, making sure not to repeat any. Keep one triangle on the geoboard. With the rest of your class, sort the triangles by angle measure. | |

You have been given four 10 cm straws, four 20 cm straws, and four pieces of pipe cleaner to act as corners. Construct and draw quadrilaterals with:
0 lines of symmetry, 1 line, 2 lines, 3 lines, 4 lines.
Look at your drawings. Can you predict the number of lines of symmetry a shape will have? Take four more 10 cm straws. Will your prediction work for regular polygons with five to eight sides? | |

A single serving cereal box is 9 cm wide, 3 cm deep, and 12 cm high. Use grid paper to draw a picture of the box. A larger box of the same cereal is three times as wide, deep, and tall. Draw the larger box to actual size on a large sheet of plain paper.
Use isometric dot paper to draw the skeleton of a triangular prism. Use plain paper and a ruler to draw the skeleton of a triangular pyramid. | |
