This is what collaborative problem solving looks like. Everyone is around the problem contributing their thinking, exploring the strategies we have been learning to use. These include: Finding a pattern, drawing a diagram, making a table, acting out the problem, working backwards, guessing and checking or trial and improvement. We have realised that in order to solve a problem we usually need to use more than one of these approaches. We also need to listen to each other, encourage each other and explain all of our thinking. Discussion or mathematical discourse enables collective knowledge building. We don't have to work in isolation but can experience success together. It's amazing what we can achieve together!
This problem asks us to make 4 squares into 2 by removing 2 matchstickes. We tried to solve this problem by drawing it. There is more than one way to solve it. Can you?
These guys did!
