Double Dare Addition!

1. Finding addition doubles is an especially mind-bending math challenge. What’s an addition double? When two of the same numeral are added together, the sum is called an addition double. For example, 8 is an addition double because 4 + 4 = 8.
2. Here’s one way students can play Double Dare Addition. Each player uses an individual dry-erase board with a Crayola® Dry-Erase Marker. You can get the class started, and then let students take turns leading the game. The leader says the sum of an addition double (such as 4).
3. All players write the addition double that makes up that sum (2 + 2). Erase with a tissue and play again. Repeat with different doubles until everyone can solve LOTS of problems.

LA: Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher led) with diverse partners on grade level topics and texts, building on others’ ideas and expressing their own clearly.

MATH: Represent and solve problems involving addition and subtraction.

MATH: Add and subtract within 20.

MATH: Use place value understanding and properties of operations to add and subtract.

VA: Use visual structures of art to communicate ideas.

Working in small groups, encourage students that have mastered simpler problems to pose more challenging problems, such as adding or subtracting a single digit from a double digit, such as 13-5=8 or 19+5=24. Encourage students to do the math mentally.
