Six templates. Page 1 is a polar grid: 10 rings around a center point and a line every 15 degrees, with the degrees marked around the outside, 0 on the right and counting counterclockwise. Page 2 has a mark for every degree around the outside, a full-circle protractor for drawing and measuring angles, and page 3 has four small polar grids. Pages 4 to 6 are blank radar charts with 5, 6 and 8 spokes: write a category at each spoke, mark a rating on each, then join the marks to see the shape of the data.
On page 2, have students draw an angle of 40 degrees from the 0 line, then one of 130 degrees, and find the angle between them. Use a radar chart for a self-check at the end of a unit: each spoke is a skill, rated 1 to 5, so students see their strengths at a glance.
Make a radar chart of a favorite sport or game: rate a few players or characters on speed, strength and skill, then compare their shapes.
