How many of you have been in a situation where many of your students raise their hands and it's hard to remember who raised their hand because they put it down? Has anyone tried using red and yellow cups or cards to be placed on the desks instead? I am in Grade 5/6 so am thinking the card route. Has anyone tried this? My daughter's teacher did the 3 Before Me which I also liked. I could incorporate both. I just find the hand raising doesn't work well for me. Any other suggestions or comments?
