Subject: Re: Teaching fractions and perimeter

One thing you could do would be to trace the tangram pieces on grid paper. Or, just use the grid paper to measure the sides of each of the pieces. Then you can talk about perimeter. What happens to the perimeter if you use two of the same pieces. Fractions in this case would be a little difficult unless you approached the problem from a geometric probability, where you computed the area of each piece and then asked what is the probability that you would land on a specific piece, say if all 7 formed the square? You might try to visit some of the games web sites that include tangrams to get more ideas, too. -Claudia, for the Teacher2Teacher service
