Teacher Resources
Teaching Notes

Discuss why the wrong answers are wrong. For example, in Q1, why is 20 - 2 ÷ 3 incorrect? (Because division happens first, which implies she shared 2 cookies, not the remaining 18).

Vocabulary
Expression: Math phrase with numbers and symbols.
Operation: Math action like add or subtract.
Common Mistakes
  • Picking the expression with the numbers in the same order as the text without checking operations.
  • Ignoring parentheses.
  • Incorrect operation choice
  • Misinterpreting keywords
  • Ignoring implied grouping
  • Confusing operation order
Differentiation
SupportHave them solve the word problem first to get a number, then solve the options to see which matches.
ChallengeAsk them to write a story for one of the incorrect options.
Discussion Questions
  • How do keywords determine operations?
  • Why are parentheses important in expressions?
  • What if the order of operations changes?
  • Can multiple expressions be correct?
Extension Activities
  • Write a math story.
  • Create word problems.
  • Act out math stories.
Parent Tip

Ask your child to explain a simple math story in words.
