Division facts up to 10: find the missing number

Key Notes :

Understanding Division: Division is the process of sharing or grouping a number into equal parts. For example, dividing 12 by 3 means splitting 12 into 3 equal groups, which equals 4.

Division Facts Up to 10: Focus on basic division facts where the divisor and dividend are both numbers from 1 to 10. This includes problems like:

  • 12 ÷ 4 = ?
  • 20 ÷ 5 = ?

Missing Number: In problems where the missing number is a divisor, dividend, or quotient, students need to use their understanding of division to fill in the blank. For example:

  • 15 ÷ ? = 3 → The missing number is 5.
  • ? ÷ 2 = 6 → The missing number is 12.

Inverses of Multiplication: Division is the inverse operation of multiplication. Use known multiplication facts to solve missing number division problems. For example, knowing that 3 × 4 = 12 helps solve 12 ÷ 3 = 4.

Patterns: Recognize patterns in division facts (e.g., the results of division by 2, 5, or 10) to help find missing numbers faster.

Using Arrays: Visualize division using arrays or groups to show how division breaks numbers into equal parts.

Learn with an example

🎯 Fill in the missing number.

_____÷ 4 = 4

  • Decide which number makes the division number sentence true. You can think of a division fact you know, or you can multiply to find the answer.
  • The division fact is: 16 ÷ 4 = 4
  • Did you remember this division fact? If not, you can find the answer by multiplying.
  • Multiply: 4 × 4 = 16
  • The missing number is 16.

🎯 Fill in the missing number.

5 ÷ ____= 5

  • Decide which number makes the division number sentence true. You can think of a division fact you know, or you can divide to find the answer.
  • The division fact is: 5 ÷ 1 = 5
  • Did you remember this division fact? If not, you can find the answer by dividing.
  • Divide: 5 ÷ 5 = 1
  • The missing number is 1.

🎯 Fill in the missing number.

 _____÷ 4 = 1

  • The division fact is: 4 ÷ 4 = 1
  • Did you remember this division fact? If not, you can find the answer by multiplying.
  • Multiply: 4 × 1 = 4
  • The missing number is 4.
