Addition and Subtraction on the Number Line: Bouncing Bunny

① This example demonstrates integer addition and subtraction through a bouncing bunny moving along a number line. ② The core mathematical concepts are integer operations and displacement on the number line, including positive/negative directions and left/right movements corresponding to addition/subtraction. ③ Construction highlights: using GeoGebra commands such as Max, Vector, Segment, and If, it builds multiple points (A, B, C), vectors (u, v), segments (c, d), and animated objects (hopb, hopa) with conditional logic to control the bunny's jump direction and distance, enhanced by images (pic1, pic2) for engagement. ④ Suitable for upper elementary to middle school students learning integer arithmetic, and useful for teachers in classroom demonstrations or for student self-exploration, turning abstract operations into a visual dynamic process.
