Match Expressions and Words

Work with your partner.

  • Take turns matching word cards to numerical expression cards.
  • Explain to your partner how you know the cards match. Challenge your partner to have clear and complete explanations.
  • Evaluate the expression on your own and then check that you agree with your partner.
  • Use any extra time to clarify and improve your work.

Hint:

  • What is the difference between an expression, such as 82 + 2 and an expression with similar quantities and operations, such as (2 + 8)2?
  • How do you know when parentheses are needed?
  • Why are brackets needed in the expression 2[( 7 + 8 ) − 2]?
