Adding Integers (5.hf)

① This example demonstrates the addition of two integers using draggable sliders a and b, with a cute teddy bear animation to engage learners. ② The core mathematical concept is integer addition, including positive and negative numbers, vector representation on a number line, and an introduction to linear functions. ③ Construction details: The GeoGebra commands Vector and Segment are used to create vectors u and v representing the addends and the number line segments; the If command controls conditional display of results. Objects include sliders a and b, points A, B, C, multiple text labels (szöveg3–szöveg9), and images (kép1, kép2) that update dynamically to show the sum. ④ Suitable for upper elementary to middle school students, this interactive tool helps visualize the geometric meaning of integer addition and can be used for classroom demonstrations or self-paced exploration.
