Earlier in the week I wanted a bit of 1-1 time with Mr H, so I set up this quick and easy geo-board activity for the older two to do. It was really simple to set up and kept them both entertained for a good hour.
I initially set the push pins up into a grid for the children, and demonstrated how to put the loom bands across. I pretty much left them up to it. It was fascinating to watch them do this. Miss E took a little while to get into a rhythm of being able to stretch the loom bands across but Mr D soon worked it out and was adding bands onto the various pins.
Once each pin had a band on it he asked what else he could do. I asked him if he could see any shapes, and he spotted a square so we talked about how he could turn that into a triangle.
He then created more squares and triangles. This was a really nice way to introduce ideas such as halving and then quartering as he worked out that by adding a band in the opposite direction he would have four triangles within each square.
Miss E just created various shapes on her side of the board – she liked to add as many bands as she could around just two pins. They could both see the pins straining a little as the bands pulled them inwards, so it was a good way to remind them about the idea of forces that push and pull (we had been looking at bridges earlier in the day).
Once Miss E had tired Mr D set about taking all the pins out and placing them back in at random points and stretching the bands around them.
They both had great fun with this and I am sure we will be using this again soon.
