Theo’s Ball Maze
Shared Reading Books · Technology · Year 4
Theo builds a maze inside a shallow tray for his cousin. A large blue wooden ball must travel from the wide start to a round finish space. He adds many card walls. “It will be a proper challenge,” he tells Grandmother, tilting the tray gently.

The ball reaches a narrow corner and stops. Theo shakes the tray, but Grandmother asks him to put it flat before trying anything else. The gap is narrower than the ball. That is not a puzzle the player can solve by choosing a better route.

They use the actual ball to check every passage. Theo moves two walls apart and makes the tight corners wider. Grandmother helps fit the broad wall bases securely. The ball can now travel through the intended route without forcing or shaking.

His cousin Megan tries next. She can move the ball, but she cannot tell which wide opening is the start. Theo adds a large plain starting circle and a different finish shape. They use clear shapes rather than extra decorative paths that could mislead the player.

Megan finds the route quickly. Theo is disappointed that it seems too easy. Grandmother asks whether he wants a challenge or a trap. They add one short dead end that the ball can leave again, keeping every passage wide enough.

Theo and Megan take turns. When Megan chooses the dead end, she tilts back slowly and returns to the junction. The mistake gives her information instead of ending the game. Theo checks that the walls stay attached through several gentle trials.

Another cousin prefers holding the tray while it rests partly on the table. Theo tries that position too. The game still works without lifting it high. They agree that players can choose a comfortable supported position and pause whenever they want.

Before putting the maze away, Theo draws the route and marks the corner he widened. “Harder was not the same as better,” he tells Megan. “A useful challenge lets you make choices, notice a mistake and try another way.”
