There is an unexplained attraction to geo boards. The moment my students see these surface, there is a round of “yay, I love these!”. For a bit of review we pulled these out and had at it.
My students partnered up for this activity. Each set of partners had a set of geo board match cards, rubber bands, and two geo boards. Partners would draw a card to take the challenge. They would independently create the figure using the available clues. After they each finished creating the figure, they would compare their boards. Of course their figures may have varied and may not have necessarily looked like the answer on the back, but if they could prove the clues then they were good to go. That is the beauty of geometry, as long as the figure was created by following the clues, by definition, they are correct.
As an extension, I had students create their own shapes and then they identified the attributes of their individual figures. These activities differentiated their learning and allowed them to think outside the box.
