Write the golden answer for a fractions tutor test

Practice: Giving the right context. About 5 minutes.

About this exercise

You're building test cases for the 5th-grade math tutor bot, and this question needs a golden answer. Your curriculum says 'common denominator' and never 'LCD', the Step line must name each multiplier (like '1/2 x 3/3'), and the bot always ends by asking the student to try a similar problem. Write exactly 3 numbered lines: '1. Step: ...' with the work shown, '2. Answer: ...', and '3. Try: ...' with one new problem and no answer. Plain text, under 60 words.

Common mistakes when you ask AI for this

  • Using the wrong words. The AI says 'LCD' or 'least common denominator' because it doesn't know your curriculum's term. Try: Say: "Use 'common denominator', never 'LCD'."
  • Skipping the multipliers. The AI jumps straight to 3/12, but your curriculum shows what each fraction is multiplied by. Try: Add: "Name each multiplier, like 1/4 x 3/3 = 3/12."
  • No practice problem. The AI ends with the answer and doesn't know your bot always asks the student to try one. Try: Add: "End with Try: one new problem, no answer."
  • A full lesson. The AI explains fractions at length, which makes a poor answer to grade against. Try: Show the shape: "1. Step: 2. Answer: 3. Try:"
  • Getting markdown back. AI formats fractions with bold or LaTeX that won't show up in the test file. Try: Ask for "plain text, no bold, no LaTeX."

  • Gives the curriculum term
  • Shows the three-line shape
  • Asks for a practice problem
