This example demonstrates the commutative property of multiplication through an interactive model, allowing students to explore products of positive and negative numbers. Key mathematical concepts include the commutative law, sign rules, and rational number operations. Construction involves using GeoGebra commands like Polygon, Corner, and Flatten to create visual representations. Suitable for grades 6-8 to reinforce number sense and rational number skills.

GeoGebra Commands & Parameters

  1. Polygon(Zip[PixelsToPoint[Corner[1], Corner[3], Corner[5], A], A, {(pixelsLeft, pixelsTop), (pixelsLeft, y(Corner[5]) - pixelsBottom), Corner[5] - (pixelsRight, pixelsBottom), (x(Corner[5]) - pixelsRight, pixelsTop)}]) → borderBox
  2. Corner(5) → layoutAppSize
  3. Polygon({(-5.5, -5.5), (-5.5, 5.5), (5.5, 5.5), (5.5, -5.5)}) → gridArea
  4. Flatten(Sequence[Sequence[(n + sub1, m + sub2), n, If[num1 > 0, 1, num1], If[num1 > 0, num1, -1]], m, If[num2 > 0, 1, num2], If[num2 > 0, num2, -1]]) → Points
  5. Corner(textSignSize, 4) → CornerSize
  6. Zip(Text[If[positive, "+", "-"], n + (((-widthText)) / 2, heightText / 2) - pointMove, true, true], n, Points) → textSequence
  7. Zip(Circle[n, 0.4], n, Points) → circles
