  2. Math Message: Write the fact family for this domino: Home Link 6.3 Follow Up: Record the fact families for these dominoes.

  3. 10 +,- 6 4 6 + 4 = 10 4 + 6 = 10 10 - 4 = 6 10 - 6 = 4

  4. Fact Triangle 10 +,- 6 4 Fact Triangles will be used to practice basic addition and subtraction facts. The word fact has an everyday meaning and a mathematical meaning. Now, use your own set of Fact Triangles and generate fact families with your partner.

  5. Beat the Calculator Materials: a calculator; a penny or a random-number generator (optional); 1 Fact Power Table (optional) Number of Players: 3 Directions: One player is the "Caller," a second player is the "Calculator," and the third is the "Brain." Players trade roles every 10 turns or so. Brain Caller Calculator

  6. Playing the Fact Power Game 2 players, or small groups For each new game, use the game mat of one of the players. Directions: Players place their markers on START. They take turns rolling a die and moving their markers the correct number of spaces across the rows, as indicated by the arrows on the game mat.

  8. Write this number in pencil: 10 For constructing fact families, roll two different colored dice. Record each number sentence using the corresponding colors. +,- Write this number in blue: Write this number in red: 6 4

  9. For the previous fact triangle, your number sentences would look like this: 6+4 = 10 4 +6 = 10 10- 4 = 6 10 - 6 = 4 Use colors that correspond to the available dice.

  10. +,- ___ + ___ = ___ ___ + ___ = ___ ___ - ___ = ___ ___ - ___ = ___ 7 7 8 9 8 0 9 0 1 2 3 4 1 2 3 5 4 5 6 6

  11. Make a fact family house. Remember, only numbers on the roof can live in the house of number sentences. 4, 5, 9 ___ + ___ = ___ ___ + ___ = ___ ___ - ___ = ___ ___ - ___ = ___
