You could give out the bingo cards to students then run through the slide show whilst students complete the square for each expression as they go along. The students could then match off the expressions with the ones on the cards.\n\nI chose to do the opposite. Before teaching completing the square I gave the students the cards and gave them a few minutes to expand the quadratics. When they had had enough time to expand the expressions we then played bingo. The students seemed to pick up completing the square that little bit quicker when I taught it this time.
