Teacher Resources
Teaching Notes

Emphasize place value: subtracting tens means subtracting from the tens place, keeping the ones place zero. Use a hundreds chart or number line for visual support. Encourage mental math strategies.

Vocabulary
Multiple of Ten: Numbers like 10, 20, 30, etc.
Place Value: The value of a digit based on its position.
Common Mistakes
  • Subtracting from the wrong place value (e.g., subtracting tens from hundreds).
  • Forgetting to write the zero in the ones place when subtracting whole tens.
Differentiation
SupportUse base-ten blocks or a hundreds chart to visually represent the subtraction. Start with smaller numbers (within 100).
ChallengeChallenge students to subtract two multiples of ten from a three-digit number that isn't a multiple of ten (e.g., 354 - 20). Introduce estimation.
Discussion Questions
  • How is subtracting 30 from 70 like subtracting 3 from 7?
  • What happens to the ones digit when we subtract whole tens?
  • Can you subtract 40 from 200 without counting? How?
Extension Activities
  • Use a hundreds chart.
  • Skip count by tens.
  • Relate to money (dimes).
Parent Tip

Ask your child to count backward by tens from a number.
