I can’t take credit* for this idea, but it is one I am loving and want to share…it’s quick entry question cards. Here’s how they work: I made about 10-12 cards and as each student came to the door, I stopped them, showed them a card and asked them the question. They told me their answer and if they were right, they got to come in and the next student behind them got a different card. If they were wrong, I told them a hint to help them answer correctly and then after they did, they were showed a new card with another question until they got one right and could come inside (if you have a long line of students, you could send them to the end of the line). Just be sure the questions are quick enough to answer in a few seconds. Kids liked this as another way to review before the test and to quickly check for understanding, I even had kids say, “ask me another!” I’m definitely going to start doing these more often with spiraled material and also on quiz/test days like today with the material for the test.
