① This example demonstrates the process of adding integers on a number line using vectors and segments, making the geometric meaning of positive and negative number addition clear. ② The core mathematical concept is integer addition, involving number line, vectors, midpoints, polygons, and other basic geometric elements to help students understand how the result's position changes on the number line. ③ Construction highlights: Using GeoGebra commands such as Vector, Segment, Midpoint, and Polygon, it creates objects a, b, A, B, u, C, D, v, R, Z, g, h, i, c, E, text1, text2, d, F, r, text3 through text7, s, G, H, I, poly1, i_1, g_1, h_1, e, etc. Vectors and segments represent addends, and text labels display the expression and result. ④ Suitable for upper elementary to middle school students, this serves as an interactive tool for teaching integer operations and as a reference for teachers creating dynamic lessons.

AI Drawing Prompt Reference

Draw a number line with two vectors u and v representing two addends, starting from the origin and pointing to A and C respectively. Then draw two segments g and h connecting Z to A and B to C. Draw segment i from D to R, and segment c from C to D, with midpoint E being the midpoint of c. Draw segment d from A to B, with midpoint F being the midpoint of d. Draw a vector s from R. Finally, draw a triangle GHI.
