You have likely seen this little puzzle on Facebook. You are asked to count the number of squares. I have seen answers from 18 to 32. I think I know the answer, but I’m not sure!
I handed a copy out to pairs of students in the class and they used different colours to identify squares. After some time, they used the Samsung tablets to take pictures and send them to the SMART Board using Extreme Collaboration. We had a lot of fun finding squares that were missed and being surprised by squares few had found. It was GREAT problem solving. Score one for the new Samsung Tablets and Extreme Collaboration! I have provided a pdf of the template for this activity here.
