Doubles: Addition facts where both addends are identical numbers (e.g., 3+3, 8+8)
- Doubles: Adding the same number twice
- Same numbers: Two identical addends
- Multiply by 2: Doubles equal number × 2
- Even results: Doubles always make even numbers
Match the doubles fact to its result: 3 + 3 = ? (Answer: 6)
Near Doubles: Addition facts where addends are consecutive numbers (differ by 1)
- Near doubles: Adding consecutive numbers
- Consecutive: Numbers that come one after another
- Neighbors: Numbers that are next to each other
- Plus one: Add one more to the doubles fact
Identify the near doubles: 4 + 5 = ? (Answer: 9)
Strategy: A planned approach to solving mathematical problems efficiently and accurately
- Strategy: A plan for solving problems
- Think: To use your mind to solve
- Connection: Linking what you know to new problems
- Efficient: Doing something quickly and correctly

Doubles: Addition facts where both addends are identical numbers (e.g., 3+3, 8+8). These always result in even numbers and form the foundation for other addition strategies.
Near Doubles: Addition facts where addends are consecutive numbers (differ by 1) such as 4+5, 7+8. These can be solved efficiently using doubles facts plus or minus 1.
