You will need a couple Jenga towers, unless you plan to do this whole group (then you only need one tower). We use about five in our classroom. You can borrow them from other teachers or grab them from Amazon.com. While students are completing a reading comprehension packet/review page place a Jenga tower in the middle of each group. As you go over each question, think aloud. Announce the correct answer. (Cue student cheering) Walk around with a pen and give students stars or checks beside the correct answer. When they get a star/check, they may take a Jenga block from the tower. If they do not answer correctly, they work through the question again. Continue through the rest of the questions, walking around to assess as you go. The goal is to see how many blocks you can successfully pull without knocking the tower down. If the tower falls, simply gather all the pieces and rebuild it.
