Geometric Construction
This example demonstrates how to create bar models for ratio problems. It involves core math concepts like ratios, fractions, geometry, and exponents. The construction uses GeoGebra commands and objects such as Makenbars, Textfield, CurlyH, Max, and Rotate. Suitable for middle school students and teachers for learning and teaching purposes.

GeoGebra Commands & Parameters

  1. Makenbars(A, StartA, Width, Height) → list1
  2. Makenbars(B, StartB, Width, Height) → list2
  3. Textfield(Alabel) → InputBox1
  4. Textfield(Aamount) → InputBox2
  5. Textfield(Blabel) → InputBox3
  6. Textfield(BAmount) → InputBox4
  7. CurlyH((0, 10), 1, 1) → f
  8. Textfield(Diff) → InputBox5
  9. Textfield(Total) → InputBox6
  10. Max(A - B, B - A) → dd
  11. Rotate(gt, -90°, R) → gtotal
