In this activity, you will receive a set of cards (can be cut out and laminated, or given out as a worksheet) that have written phrases that represent algebraic expressions. In pairs, students read the words on the card and then write their algebraic expression on the line with the corresponding number. When students finish writing their expressions on the lines, a second set of cards can be distributed. These cards have algebraic expressions on them. Students match up what is on the answer card with what they wrote on the line. This sparks great conversation regarding whether the expression that they wrote is "acceptable" and therefore correct. Students also learn that there are many ways to interpret an algebraic expression. These answer cards can also be distributed as a worksheet where students can check off each card as they go through their answers.
This can also be used as a matching game. The cards with the words can be copied (and laminated) on one color paper and the cards with the algebraic expressions can be copied on a different color. Students can match a card words to a card with an algebraic expression.
This activity can also be used to play memory. All cards can be copied onto the same color paper. Students flip them upside down and they must find pairs; one card with words and one card with the corresponding algebraic expression.
