Today we offered children an opportunity to build with big blocks. Of course, right away one child had an idea that sparked lots of interest and curiosity. GB began using the long blocks and lining them up against the shelf creating what appeared to be ramps. Then, he used a slippery square building block to go down the ramp. Spark! Many children came over and wondered what else would go down the ramp? I asked, "Do we need other ramps? From the collaboratory?" CB - "Yes! Go to the collaboratory!" So, we went and looked for ramps that felt just right. Once we found ones that fit his idea, we brought them back to the room for all to enjoy. I asked, "How can we stop the balls?" JAM - "I know! I'll put the block here!" LB - "What if we made a bridge?" GB - "I'm building a trap" "I'm trapping the balls!"
