Your teacher will give you a set of cards. Take turns with your partner to match two equivalent expressions.
For each match that you find, explain to your partner how you know it’s a match.
For each match that your partner finds, listen carefully to their explanation. If you disagree, discuss your thinking and work to reach an agreement.
