Teaching Notes

This collection focuses on helping second graders differentiate between addition and subtraction scenarios within word problems. Encourage students to identify keywords, draw models, or use number lines to visualize the problems and select the correct operation.

Vocabulary
Mixed: A mix of operations.
Operation: Adding or subtracting.
Common Mistakes
  • Guessing the operation instead of look for clues.
  • Confusing 'how many more' (comparison subtraction) with addition.
  • Forgetting to check if the answer makes sense.
Differentiation
SupportProvide manipulatives or drawing templates (e.g., part-part-whole mats, bar models). Highlight keywords that indicate addition (e.g., 'in all,' 'altogether,' 'more') or subtraction (e.g., 'how many left,' 'difference,' 'flew away').
ChallengeEncourage students to write out the equation with a variable before solving. Challenge them to create their own mixed operation word problems within 20 or explain their reasoning verbally/in writing.
Discussion Questions
  • How did you decide if you needed to add or subtract for this problem?
  • What clues or keywords in the problem helped you find the answer?
  • Can you explain your strategy for solving this problem to a partner?
  • What would happen if the numbers in the problem were much larger?
Extension Activities
  • Make up mixed problems.
  • Use a number line.
  • Draw the story.
Parent Tip

Use toys to act out adding and taking away.
