Key Concepts

Master the make 10 strategy for efficient addition

What is Make 10?

The make 10 strategy helps us add numbers by first making 10, then adding the rest. It makes addition faster and easier!

Examples:

8 + 6: Make 10 from 8 by taking 2 from 6
7 + 5: Make 10 from 7 by taking 3 from 5
9 + 4: Make 10 from 9 by taking 1 from 4

Step-by-Step Process

Follow these steps to use the make 10 strategy: 1) Find what number needs to be added to make 10, 2) Take that amount from the other number, 3) Add 10 + the remaining amount.

Examples:

8 + 6: 8 needs 2 to make 10, take 2 from 6, 10 + 4 = 14
7 + 5: 7 needs 3 to make 10, take 3 from 5, 10 + 2 = 12
9 + 4: 9 needs 1 to make 10, take 1 from 4, 10 + 3 = 13

Visual Tools

Use ten frames, number bonds, and drawings to help visualize the make 10 strategy.

Examples:

Ten frame: Fill 10 spaces first, then add extras
Number bonds: Show how numbers break apart
Drawings: Use circles or blocks to represent numbers

Interactive Practice

8 + 6 using Make 10

Problem:

Use the make 10 strategy to solve 8 + 6

Solution:

8 + 6 = 14

Steps:

  1. 1Look at 8 + 6
  2. 28 needs 2 more to make 10
  3. 3Take 2 from 6: 6 - 2 = 4
  4. 4Now we have: 8 + 2 + 4
  5. 58 + 2 = 10, so 10 + 4 = 14

Visual:

8 circles + 6 circles = 8 circles + 2 circles (make 10) + 4 circles = 14 circles

7 + 5 using Make 10

Problem:

Use the make 10 strategy to solve 7 + 5

Solution:

7 + 5 = 12

Steps:

  1. 1Look at 7 + 5
  2. 27 needs 3 more to make 10
  3. 3Take 3 from 5: 5 - 3 = 2
  4. 4Now we have: 7 + 3 + 2
  5. 57 + 3 = 10, so 10 + 2 = 12

Visual:

7 circles + 5 circles = 7 circles + 3 circles (make 10) + 2 circles = 12 circles

9 + 4 using Make 10

Problem:

Use the make 10 strategy to solve 9 + 4

Solution:

9 + 4 = 13

Steps:

  1. 1Look at 9 + 4
  2. 29 needs 1 more to make 10
  3. 3Take 1 from 4: 4 - 1 = 3
  4. 4Now we have: 9 + 1 + 3
  5. 59 + 1 = 10, so 10 + 3 = 13

Visual:

9 circles + 4 circles = 9 circles + 1 circle (make 10) + 3 circles = 13 circles

6 + 8 using Make 10

Problem:

Use the make 10 strategy to solve 6 + 8

Solution:

6 + 8 = 14

Steps:

  1. 1Look at 6 + 8
  2. 26 needs 4 more to make 10
  3. 3Take 4 from 8: 8 - 4 = 4
  4. 4Now we have: 6 + 4 + 4
  5. 56 + 4 = 10, so 10 + 4 = 14

Visual:

6 circles + 8 circles = 6 circles + 4 circles (make 10) + 4 circles = 14 circles
