Are you up to the challenge?

Fellow blogger Michelle over at Delightful Learning has put together an Instant Challenge Meme. Each week will bring a new timed problem for the kiddos to work together as a team and solve, stretching their imaginations and reasoning skills. For more info about the meme and to read about inspiration behind the challenges, check out Michelle's Instant Challenge intro post.

The first challenge is bridge building! This is a topic we have messed a lot with in the past, but with a new twist: you have to build the bridge with index cards in 5 minutes! You can read about the bridge builder challenge and download complete instructions here. We did make a slight change and added an initial 2 minute brainstorming period where the kiddos could come up with ideas and discuss plans before the 5 minute construction stage.

I allowed them to use their 2 minute testing period to improve the bridge and retest.
