Building with Cardboard and Tubes

I love using reusing items and recycling materials. So I save a lot of stuff. I've called it a sickness...Teacher Tom calls it being a middle-class bag lady.

This week I was reminded why I save this stuff. In the block center - blocks, cardboard pieces, and cardboard tubes. Here's what happened. (I only have a few photos; it was a busy morning.)

We've used these materials before but this group of boys surprised my at their creativity and inventiveness in using them. I love it when the kids surprise me.
