In year 1 we are working on addition and substraction till 10. The kids love to work with the new "MoreToMath"-material.
At the beginning they should build a snake out of 8 nubs and write down the addition task. Later we collected all possibilities and compared it. After that, they did the same with a snake out of 10 nubs and then snakes only using green bricks.
At the end they could built their own snakes and wrote down the addition task. It was amazing to see how motivated they wrote a lot of tasks and checked it independently by counting the nubs.
