This example provides an interactive flash‑card addition practice tool where addends can be selected to match individual needs and a slider controls the time delay before the answer appears. The key mathematical ideas are addition, the choice of addends, and timing control. It is built in GeoGebra using RandomElement to pick addends, RemoveUndefined to handle undefined objects, lists and buttons for dynamic problem generation, and a slider for the delay. It is suitable for primary‑school arithmetic practice, offering personalized drills to improve speed and accuracy.

GeoGebra Commands & Parameters

RemoveUndefined(list1) → list2
RandomElement(list2) → b
RandomElement(list2) → a

AI Drawing Prompt Reference

Create an interactive addition flashcard practice interface. Start with a customizable list of possible addends, remove any invalid entries to form a valid candidate set, then randomly choose two numbers from that set as the current addends and display them as an addition problem. Include a button to generate a new problem and a draggable slider that controls the delay before the answer appears. The design should support primary-school arithmetic drills, emphasizing selectable addends, random problem generation, and timed answer reveal.
