Students were to work in groups to build with the connecting cubes a small building a medium building and a big building. 

First try

Second try, after we explained to them to work together and make a medium size building.

Hajar's group worked together to create a medium building.

Now they were to make the biggest or tallest building.

If everyone has the blocks in their hands can we build one that it the tallest?

I told them to work together and put the blocks together said Warrick.

This was an experiment to see how well the students worked well together using their words and sharing their ideas. To build one tower.
