polygon paper

dotty ideasI love dotty paper for exploring tessellations. But what else could you use it for? A simple game I came up with this year was an adaptation of boxes, but with triangle dotty paper. Players get 1 point for making a triangle, but 3 points for making a rhombus and 6 points for making a hexagon. I am sure there are other rules you could put in there to develop this game further. The Pascal's triangle activities on this website also came from messing around with triangle dotty paper. I have previously used dotty paper for drawing Koch snowflakes and using them to investigate area and perimeter. There are a range of excellent NRICH tasks that use square dotty paper such as Pick's Theorem and Tilted Squares (see images on the right). When I taught level 46 triangles and quadrilaterals this year, I used triangle dotty paper and we drew tessellations to investigate angles in a straight line and angles round a point. If you come up with any nice ideas using dotty paper please post them on the blog.
