What will you learn in this lesson?

Students use basic division facts and patterns to divide multiples of 10, 100, and 1,000 mentally, such as 4,200 ÷ 7, without needing long division.

  • Uses basic facts and patterns to divide multiples of 10, 100, and 1,000
  • Divides mentally by multiples of ten
  • Completes and explains division patterns

💡 Tip: When dividing by multiples of ten, cross out the same number of zeros from the dividend and the divisor: 2,400 ÷ 60 = 240 ÷ 6 = 40.

Worked examples from the Division Patterns lesson questions

If 36 ÷ 4 = 9, what is 3,600 ÷ 4?
  • 900
  • 90
  • 9,000
  • 9
✓ 900
3,600 = 36 hundreds, and 36 ÷ 4 = 9, so 36 hundreds ÷ 4 = 9 hundreds = 900.
What is 4,200 ÷ 7?
  • 600
  • 60
  • 6,000
  • 700
✓ 600
The basic fact is 42 ÷ 7 = 6, and 4,200 = 42 hundreds, so the answer is 6 hundreds = 600.

What is 2,400 ÷ 60?
  • 40
  • 400
  • 4
  • 4,000
✓ 40
The basic fact is 24 ÷ 6 = 4; 2,400 = 240 tens and 60 = 6 tens, so the answer is 240 ÷ 6 = 40.
What is 35,000 ÷ 5?
  • 7,000
  • 700
  • 70,000
  • 5,000
✓ 7,000
35 ÷ 5 = 7, and 35,000 = 35 thousands, so the answer is 7 thousands = 7,000.
Complete the pattern: 48 ÷ 6 = 8, 480 ÷ 6 = 80, 4,800 ÷ 6 = ?
  • 800
  • 80
  • 8,000
  • 480
✓ 800
Each time the dividend gets one more zero, the quotient gets one more zero: 4,800 ÷ 6 = 800.

FAQ about the Division Patterns lesson

If 36 ÷ 4 = 9, what is 3,600 ÷ 4?

The dividend is 100 times greater, so the quotient is also 100 times greater: 3,600 ÷ 4 = 900.

How do I calculate 35,000 ÷ 5 mentally?

35 ÷ 5 = 7, then add the three remaining zeros, so the quotient is 7,000.
