① This interactive GeoGebra example generates random integer subtraction problems and provides immediate feedback, helping learners master integer arithmetic. ② The core mathematical concept is integer subtraction, including rules for subtracting positive and negative numbers, and understanding direction and distance on the number line. ③ Construction highlights: using GeoGebra commands such as Point, Random, Vector, Textfield, and Mirror to create dynamic objects—random number generators, input boxes, buttons, and text displays—where buttons generate new questions and input boxes accept answers with instant correctness feedback. ④ Suitable for upper elementary to middle school students for integer practice, and useful for teachers as a classroom demonstration or self-paced drill tool, combining engagement with pedagogical value.

GeoGebra Commands & Parameters

  1. Point(f) → A
  2. Point(g) → B
  3. Random(-10, 10) → a
  4. Random(-10, 10) → b
  5. Vector(A, C) → u
  6. Vector(B, D) → v
  7. Textfield(c) → InputBox1
  8. Mirror(D, x = x(B)) → D'
  9. Vector(B, D') → w

AI Drawing Prompt Reference

Create a dynamic integer subtraction practice diagram with two randomly generated integer points, vectors showing their difference, and displaying the subtraction result. Include an input box for users to enter answers, with vector direction and text feedback to show correctness. Add a button to generate new random integers, visualizing the subtraction process on a number line to demonstrate rules for positive and negative numbers and changes in distance.
