① This GeoGebra example is an interactive ratio word problem practice that generates random questions and provides immediate feedback to help students master ratio concepts. ② The core mathematical concepts are ratios and rational numbers, involving setting up and solving proportional relationships, with bar charts used to visualize data. ③ Construction highlights: The Polygon command is used to draw geometric elements, Random generates random parameters (num1, num2, num3), Textfield and InputBox1 provide input interfaces, a Done button triggers feedback, conditional checks (RightCheck, WrongCheck) display correct/incorrect messages, and TryAnother and HowDidIDo buttons allow retry and solution viewing. ④ Suitable for upper elementary to middle school students, for classroom practice or self-study, and as a template for teachers to create interactive exercises.

GeoGebra Commands & Parameters

  1. Polygon((1.3, 5), (12.9, 5), (12.9, 2.5), (1.3, 2.5)) → WorkingSpace, f, g, h, i
  2. Random(1, 2) → ItemNum
  3. Random(2, 5) → k
  4. Textfield(UserText) → InputBox1
  5. Polygon((13, 4.2), (15, 4.2), (15, 2.5), (13, 2.5)) → AnswerBox, j, l, m, n

AI Drawing Prompt Reference

Draw an interactive practice interface for ratio word problems. Start with a large rectangle on the left side as the working area, where the problem and visual aids will appear. Inside this rectangle, randomly generate a number to serve as a parameter for the question. To the right of the working area, place a smaller rectangle as the answer box, with a text input field beside it for the user to type their answer. Below the interface, add a button to submit the answer and trigger feedback. When the answer is correct, display a 'correct' message inside the working area; if wrong, show an 'incorrect' message. Additionally, include two more buttons: one to generate a new random question, and another to view the solution steps. The overall layout should be clean and straightforward, suitable for students practicing ratio concepts.
