This weekend has been nice as the holiday has given me a chance to catch my breath. I spent some time browsing the net for ideas. I stumbled upon a kindergarten teacher's site that had a template for Connect Four created with Google Draw.
What she did was merely play with a class from a different state in order to show her students the power of the internet. I would like to suggest something with a little more substance. You could create content based questions and the students would have to answer the question correctly before moving a piece into play. It would really be cool to partner up with a class in a different school. In fact, let your students create the questions that will be asked of the other class.
This would make a wonderfully engaging review task!
