Where is my Fact Family?

Explicit Instruction/Teacher modeling

• Direct attention to the large dominoes posted around the classroom. Let the class know that these dominoes will be involved in an activity.
• Give each student an equation strip from Set 1. Explain that students will need to find the dominoes that match their equations.
• Demonstrate the exercise by selecting a strip, reading it aloud, then moving to its corresponding domino.

Guided Practice

• Give students about five minutes to find their dominoes. Once they finish gathering, there should be multiple students at each domino, with the exception of the 0 family domino.
• Ask students how many facts they think are in a fact family. Have them look around at how many students are at each domino before they respond.
• Explain that fact families usually contain four equations. When the addends of the family are the same, they contain two. The only exception is the 0 family, which only contains one.
• If there's enough time remaining, allow students to repeat the activity with equations from Set 2.

Independent working time

• Have each student select one or two of the dominoes in the room.
• Ask students to copy down their dominoes on a sheet of paper and write down the fact families for those dominoes.
