Whatever students type in is what they’ll see on the images! That feedback will showcase the brilliant and unique ways your students think about mathematics . . . so don’t keep them to yourself!
Let students lead by getting them excited about each others’ thinking. Find an expression you didn’t consider, or one that is wrong — and interesting! Consider selecting and sharing these expressions with the class and asking, “How do you think this student saw the pattern growing?” Give your students the opportunity to experience the joy and surprise of seeing each others’ brilliance.
