This is a super fun way to reinforce concepts!
Each student is given one card and a recording sheet. The card is placed on their desk, and will remain there for the duration of the game.
The teacher will announce the start of the game. Students complete the question at their desk as quickly as they can. They record their answers on the recording sheet. After a prescribed amount of time (30 seconds, 1 min or whatever you feel is appropriate), say "SCOOT". Students will physically move to another desk with another card. Play continues until all cards have been answered.
Once completed, the teacher will review the answers, and have students check their work. The student with the most correct answers is the winner!
