Connecting Words and Algebraic Expressions

Students are given a set of cards that have either an algebraic expression or a word sentence. They then have to match up the expressions with the word sentences. This is not meant to be a big activity but just a quick one to help kids connect the different forms. You could use this in grade 7, 8 or 9.

  • Gr7 - translate phrases describing simple mathematical relationships into algebraic expressions, using concrete materials
  • Gr8 - translate statements describing mathematical relationships into algebraic expressions and equations
  • MPM1D, MFM1P - As review
  • There are four sets. Print each on a different colour card stock (there is no real reason for this except that if the cards get mixed up it is easier to get them back into their groups) and laminate (if possible) then cut them out.
  • Mix each set up and put each into an envelope
  • Because there are only four sets, you will have to make up multiple sets depending on how big your class is. 

  1. Put students into pairs or triads
  2. Give each group one set of cards
  3. Students are to match up the word sentence with the algebraic expression
  4. If time permits, have groups trade sets for a different colour.
  • Number Sentences (doc) (pdf)
Did you use this activity? Do you have a way to make it better? If so tell us in the comment section. Thanks
