I had two challenges for them - one to see how quickly they could get to 12 (number of people in my advisory) and whats the largest number we can get to.
It was more effective than I thought! We stood in a circle (facing outwards) and tried to count without saying the number at the same time as someone else. The first few time we got stuck on 8 - we just couldn't get past it! We had a moment to get some feedback/suggestions and with a strategy in hand we went from a time of 1min 36 to 10.1 seconds! For the next challenge, we got stuck in the teens. Again after a discussion...I couldn't stop the numbers from coming...they kept going! And before we knew it we had reached ONE HUNDRED! There were cheers at the end - thats got to be a good sign!
