Leo noticed a long stick resting on the wall and asked if he could use it to make a bridge. Jack assisted him by creating one side of the base (using 5 tree cookies). Meanwhile Leo and Charlotte stacked six cookies on the opposite side. Jack placed the stick on top of the two bases.
Teacher- What is happening to the bridge?
Leo- It’s falling. It’s falling, the people will fall into the water.
Teacher- Do you know why the people will fall in the water?
Leo- It’s not even.
Jack- It has to be the same on both sides so the people won’t fall off. ( A lesson in symmetrical building)
Leo- We need a railing.
Teacher- Why do we need a railing?
Leo- If the people don’t have anything to hold onto the people will fall off the bridge.
Teacher- So what do you suggest we do about that?
Jack- We need to make a railing so the people don’t fall into the water.
