In collections Elementary School Applets
This example uses ten sticks to visually demonstrate addition within 20. The core mathematical concepts include addition and number combination. The construction uses GeoGebra commands such as Sequence, Polygon, Random, Flatten, Textfield, Vector, and Translate. Suitable for first or second-grade students to learn addition.

AI Drawing Prompt Reference

Draw a ten-stick addition diagram with two rows of 10 sticks each. The left row represents one addend, and the right row represents the other addend. Randomly move some sticks from the left to the right to form a new combination, showing the result of the addition. Include an input box on the right to enter the total sum.
