Story-based addition practice
George and Charlie Addition turns an addition sentence into a short visual story. Instead of seeing only 5 + 3, the learner sees George with five objects, Charlie bringing three more, and then both groups together. That makes the meaning of addition concrete before the child taps an answer.
Two levels: up to 10 and up to 20
The add up to 10 level is built for early counting confidence, while the add up to 20 level asks slightly larger and more careful questions. Each run uses a shuffled queue from the selected level and does not repeat the same ordered addition question during that session. Zero and one are included occasionally so learners still understand them, but they appear less often than richer counting questions.
How the game works
Every round has three steps. First, George sits with his starting group. Next, Charlie drives in with a cart carrying more matching objects, or sometimes no extra objects. Finally, the objects are shown together and the player answers how many George has now. The answer buttons stay large and separate from the moving scene so the numbers remain easy to see.
Why moving objects help kids add
Young learners often need to see quantities before number sentences feel natural. By showing the first group, the incoming group, and the final combined group, this game supports counting on, combining sets, and checking a total. The animation gives a reason to recount rather than guessing from memory.
Built for phones, tablets, and computers
The standalone play folder includes its own HTML, CSS, JavaScript, copied local sound effects, generated instruction audio, thumbnail, and open graph image. The layout adapts for desktop, tablet, and mobile landscape screens. If a narrow phone is held in portrait orientation, the game pauses behind a styled rotation prompt so the scene and answer choices do not become cramped.

Practice tip for parents and teachers
Ask the learner to say the story aloud before choosing: George has five apples, Charlie brings three more apples, so five plus three equals eight. Speaking the sentence connects the animation, the written equation, and the final answer. After a few rounds, encourage counting on from the larger number instead of recounting every object from one.
