I painted tubes green that I had previously cut into varying lengths.
The triangle paper was put out for a pattern to follow.
I was surprised to see how the first child and her parent built their tree. Using the tubes to outline the triangle they filled it with the smaller tubes. Not what I had in mind but it was creative and works.
I saw the next family playing with the tubes, enjoying slipping them inside each other. I pointed out the paper triangle and asked if they could build a tree by placing the tubes on it. It took them a few tries, measuring each tube to the next but they did it.
Then today I saw this little one having fun pulling the tubes out of the basket.
I guess it is a multi-use toy.
