Help the robot crab reach the star. One arrow, one discovery!
Four missions to explore with an adult. Suggested ages: 5–7, with shared reading. No grade or timer. Discoveries from this visit disappear when you leave; they do not change track progress.
First, see an example
1→★2
The robot is on square 1. The → arrow moves it one square right: it reaches square 2. The starting square does not count as a step. Arrows point to the sides of the screen; they do not turn the robot.
Preparing the activity. Meanwhile, explore the example and guide below.
Start with one arrow or choose any mission. You can stop whenever you need.
1. One arrow, one action
Choose an arrow that takes the robot to the star.
1. Prepare the arrows
Select an arrow in the queue to change it. Then choose another direction or swap its position. Up to 8 arrows.
Choose the first arrow.
2. Where will the queue end?
Before testing, select a square on the board. That is your prediction, not a right or wrong answer.
Robot = start · Star = destination · Rock = do not cross
3. Test one arrow at a time
A clue
Find the robot and the star. Is the star above, below or beside it? Point before choosing an arrow.
The path we tested
✦
An idea you tested!
You tried all eight boards! Take a break. Later, invent a path on paper and explain how it works.
Guide for the grown-up
Read one instruction at a time. Ask the child to point to the start and star, predict, then test. If something differs, ask: ‘Which was the first arrow that did not do what you expected?’ Let the child try a change. They can explain by speaking, drawing or pointing; we do not record these responses.
After the screen: draw another board. Move the star and create a new queue. On another day, try explaining without copying the first solution.
Play on paper
Print the board and cards below, or draw them. Use a finger or a large drawing as the robot. An adult reads the arrows one at a time. Avoid small pieces. Compare with the worked example after trying.
Paper mission: robot on square 9, star on square 3 and rock on square 10. Try reaching the star without crossing the rock.

The Rullst Academy checks the linked GitHub ID, its installation and the repository list to validate the destination. After your confirmation, it sends the reviewed text to a new file in the selected repository. The text and installation tokens are not stored in the Rullst Academy database. Destination preferences stay in this browser, separately per account, and can be removed with Clear local data. Deleting a Rullst Academy account does not delete files on GitHub; manage files and revoke the installation on GitHub itself.
