Subtraction game

Maya and Leo Takeaway

Maya and Leo Takeaway is a visual subtraction game for early learners. Maya starts with a group of objects, Leo waits nearby with his cycle cart, and then objects move into Leo's basket before the taken objects are crossed out instead of disappearing. Children count the objects that are not crossed out and choose the correct answer. The game includes subtraction up to 10 and subtraction up to 20 levels, shuffled non-repeating questions, narration, touch-friendly answer buttons, and a landscape prompt for narrow portrait screens.

Subtraction as a take-away story

Maya and Leo Takeaway turns each subtraction fact into a short story. Instead of showing only 9 - 4, the game shows Maya with nine objects, Leo taking four away, and four objects crossed out. The learner can still see the full starting group, which makes the meaning of take away clearer than making objects vanish.

Two levels: up to 10 and up to 20

The first level keeps the starting number between 0 and 10. The second level increases the starting number up to 20 for a larger counting challenge. Every subtraction sentence has a non-negative answer, so learners do not meet negative numbers in this early practice game. Questions that start from 0 or 1 appear rarely, while richer take-away examples appear more often.

How each round works

Each round begins with Maya, Leo, and a visible group of pears, cookies, or gems. Leo waits beside his cycle cart, then the take-away objects move into his basket before he rides away. The game marks those objects with a red cross, keeps them in the group, and asks how many are left. Large answer buttons stay along the bottom edge so the choices are easy to tap on phones, tablets, and computers.

Why crossed-out objects help

Many children understand subtraction faster when they can compare the original amount, the taken-away amount, and the remaining amount at the same time. Crossing out objects keeps the starting quantity visible while showing which objects no longer count. This supports counting back, counting the uncrossed objects, and connecting the picture to the written minus sentence.

Scoring and feedback

A first-try correct answer earns one point. If the learner chooses a wrong answer, that question becomes worth zero points, but the player can keep trying until the correct answer is found. The final screen shows score, correct first tries, questions with a wrong try, total questions, and selected level in a compact two-row table.

Responsive standalone play

The game runs in its own play folder with local HTML, CSS, JavaScript, copied sound effects, generated narration audio, a thumbnail image, and an open graph image. The visual scene adapts for desktop, tablet, and mobile landscape screens. If a narrow phone is held upright, a styled rotate prompt asks the player to use landscape mode so the subtraction scene and answer choices have enough room.

Practice tip for adults

Ask the child to describe the picture before answering: Maya has twelve gems, Leo takes away five gems, so twelve minus five means the uncrossed gems are left. Saying the story aloud links the animation, the crossed-out objects, the equation, and the answer choice.
