Place Value × 10 Pattern

What mastery looks like

  • Explain that the 3 in 3,000 is ten times the 3 in 300
  • Complete: 700 ÷ 70 = __ and explain using place-value reasoning
  • State how many times greater the value of the 5 in 50,000 is than the 5 in 5,000

Check your understanding

Can Place Value × 10 Pattern explain that in 700, the 7 is worth 10 times more than in 70 — because moving one place to the left multiplies the value by 10?
