When Does Zero Matter?

Work with a partner.

  • Take turns choosing a card. Decide whether the statement on the card belongs in the “Always True” or  “Sometimes True” column.
  • Explain to your partner how you made your decision. Your partner should either agree with your explanation or challenge it if he or she thinks your explanation is not clear, correct, and complete.
  • When you both agree, move the card into the appropriate column.
