It was fun to mix and match the tangrams to make rectangles. It made me think and I used trial and error to find ways. I remember feeling excited when I found several ways but gradually got a little irritated when I could not find a way to use all 7 pieces to make a rectangle. This reminded me that it takes patience to do an activity like this. It also makes me think about what children would feel should they be posed with a problem like this.
Nonetheless, we still managed to solve the problem. There are actually many ways to solve the problem. The pictures below are just some examples among the many.
