The children in 213 decided to see which group could make the highest tower with MAB tens. It was tricky. There were many tumbling towers, but we were able to come up with some designs that stood up. It was interesting to hear all the groups working and they quickly discovered that it was best to work together to build their towers. The group that built the highest tower found out that you needed to stack the tens vertically and horizontally to achieve a sturdier building. The most interesting thing we discovered was that working together we can achieve a better result.
