This example demonstrates the use of a unit fraction bar and two adjustable fraction bars to explore operations like addition, subtraction, division, and common denominators. Core math concepts include fraction operations and finding common denominators. Construction highlights the use of GeoGebra commands such as LCM (Least Common Multiple), If (Conditional Logic), Polygon, Textfield, and Sequence, along with objects like s2, d1, d2, cd, e, ns2, s1, ns1, poly1, a, b, c, d, n1, n2, text1, text2, inputBox1, inputBox2, inputBox3, inputBox4, w1, w2, text3, Frac1, text4, Frac2, text5, inputBox5, inputBox6, list1, text6, text7, text8, text9, text10, text11, and expressions like “= ” + (n2 ns2) + “/” + (d2 ns2), along with button1. Suitable for upper elementary and middle school students learning fraction operations and geometric intuition.

GeoGebra Commands & Parameters

  1. LCM(d1, d2) → cd
  2. If(e ≟ 0, s2, cd / d2) → ns2
  3. If(e ≟ 0, s1, cd / d1) → ns1
  4. Polygon((0, 0), (5, 0), (5, 1), (0, 1)) → poly1, a, b, c, d
  5. Textfield(n1) → inputBox1
  6. Textfield(d1) → inputBox2
  7. Textfield(n2) → inputBox3
  8. Textfield(d2) → inputBox4
  9. Sequence(Polygon[(i, -2), (i + w1, -2), (i + w1, -1), (i, -1)], i, 0, 5 * n1 / d1 - w1, w1) → Frac1
  10. Sequence(Polygon[(i, -4), (i + w2, -4), (i + w2, -3), (i, -3)], i, 0, 5 * n2 / d2 - w2, w2) → Frac2
  11. Textfield(s1) → inputBox5
  12. Textfield(s2) → inputBox6
  13. Sequence(Polygon[(i, 0), (i + 5 / cd, 0), (i + 5 / cd, 1), (i, 1)], i, 0, 5 - 5 / cd, 5 / cd) → list1

AI Drawing Prompt Reference
