Questions & Answers

Question: I don't know when to add or subtract in word problems. How can I tell the difference?

Answer: Great question! Here's how to identify the operation:

  • Words for Addition: more, altogether, total, sum, combined, in all, both, added to, increased by
  • Words for Subtraction: left, remaining, take away, less, fewer, minus, difference

  • Use the question stem: Repeat the question and fill in the answer
  • Include units: Always include the item being counted
  • Check for completeness: Does the answer address the question?
  • Practice regularly: Start with simple problems and build complexity

For example: Question: "How many apples does Tom have now?" Answer: "Tom has 5 apples now."

Question: How do I teach students to check their answers in addition word problems?

Answer: Teaching checking builds confidence and accuracy:

  • Count all objects: Actually count to verify the total
  • Draw a picture: Visual representation confirms the answer

  • Context check: Does the answer make sense in the story?
  • Re-read: Ensure you answered the specific question asked

Encourage students to always ask: "Does my answer make sense?"
