Addition Practice Interactive Tool: Random Problems with Instant Feedback

① This example is an interactive practice tool for integer addition, generating two random numbers and letting users input the sum, visually demonstrating the addition process. ② The core mathematical concept is arithmetic addition within real numbers, focusing on integer summation, while incorporating random generation and input interaction to foster algebraic thinking and basic arithmetic skills. ③ Construction highlights: using GeoGebra's Random command to generate addends a and b, a Textfield and InputBox1 for user answers, button1 to trigger checking, ans to store the user's answer, trials and solutions to count attempts and correct answers, and text2/text3/text4/text5/text6 for feedback messages, forming a complete practice loop. ④ Suitable for early elementary students or beginners practicing mental addition, and useful for teachers in classroom demonstrations or for self-paced learning, with instant feedback and score tracking to enhance motivation.
