Get your students to participate more often with this incentive punch card. Carry a hole puncher with you and acknowledge when students make valuable contributions to the class discussions by punching their card. Reward them when they fill the card!
Something I found to work well was to have a gumball machine in the classroom. Instead of a treasure box or something similar, when the kids fill their punch cards, they can visit the gumball machine. Each color gumball is a different reward that the class came up with together (most free, in class incentives).
Hope you enjoy!
