Last week I wrote about setting a homework challenge to learn muscles of the body as an online game - the students then had to post screen grabs on google+ to show they had done it and to be in contention for the hallowed prize of 'King of the Muscles' and a cafe voucher. I wasn't quite sure how it was going to go, but by Thursday the buzz in all my senior classes was about ' poke-a-muscle '. The boys were so excited about it they'd post a score, and then find out that someone had beaten them, and then rush out of the class at interval to get to a computer and beat the top score. I even had an email on Saturday (two days after the due date) from two boys who had been practicing and spent the afternoon working together to try and beat the original high scores they had submitted with the homework!!!
