Making 10 Strategy: A mental math technique where you break apart one number to make 10 with the other number, then add the remainder.

Making 10 Solution Steps:
  1. Identify the first number: Look at 9
  2. Determine what's needed to make 10: 9 needs 1 more to make 10
  3. Break apart the second number: Split 2 into 1 and 1
  4. Make 10: Add 9 + 1 = 10
  5. Add the remainder: 10 + 1 = 11
Problem
9 + 2
Break 2
1 + 1
Make 10
9 + 1 = 10
Step 1: Identify how many more 9 needs to make 10

9 needs 1 more to make 10 (9 + 1 = 10)

Step 2: Break apart 2

Split 2 into 1 and 1 (2 = 1 + 1)

Step 3: Make 10

Questions & Answers

Question: Why is the making 10 strategy particularly useful when adding 9?

Answer: The making 10 strategy is especially effective with 9 because:

  • Only 1 away from 10: 9 needs just 1 more to make 10, so it's always easy to take 1 from the other number
  • Predictable pattern: 9 + b = 10 + (b-1), which creates a clear pattern for students
  • Simple decomposition: Only need to break apart 1 from the other number, not complex splitting
  • Easy mental math: Once students know 10 + something, they can easily add to that

This makes addition with 9 much simpler and more reliable than counting on from 9.

The strategy builds confidence and fluency with 9 additions specifically.

Question: How do I teach students the pattern when adding 9?

Answer: The pattern with adding 9 is very consistent:

  • 9 + 2 = 11: The sum is 1 more than the second number
  • 9 + 3 = 12: The sum is 1 more than the second number
  • 9 + 4 = 13: The sum is 1 more than the second number
  • General rule: 9 + b = (b+1) more efficiently calculated as 10 + (b-1)

Show students that 9 + something is like adding 10 to that number and then subtracting 1. This creates a reliable pattern they can count on.

Practice with multiple examples to help them recognize and internalize this pattern.

Question: What activities help students master making 10 when adding 9?

Answer: Effective activities for making 10 with 9 include:

  • 9 + ? flashcards: Focus specifically on 9 addition facts
  • Pattern recognition games: Have students identify the pattern (sum is 1 more than second number)
  • Ten frame activities: Show 9 dots filled, then add more to see the making 10 process
  • Partner activities: Students take turns giving each other 9 + ? problems
  • Real-life applications: Use word problems that naturally involve adding 9

Incorporate games that make practice fun, like "Race to 10" when adding 9. Regular, short practice sessions are more effective than long, infrequent ones.

Use multiple representations - concrete objects, visual models, and abstract equations - to build strong conceptual understanding.
