Write or draw an algorithm: move right, check for an obstacle, then move up.
Hint: Use START, actions, a decision, and END.

Represent a sequence and decision as a clear algorithm.
Read each obstacle row and write the arrow sequence that reaches the star safely.
Choose a strategy, show one idea clearly, and check your work.
Pattern: red, blue, red, blue, ... The repeating unit is red, blue, so red comes next.

What changed in your thinking after you checked your first idea?
Accept equivalent explanations when the reasoning is accurate. Open-ended tasks include review criteria instead of a single model answer.
A learner may list actions but leave the decision without two clear outcomes.
Ask the learner to draw or label one example, then explain the next step aloud. Ask: "What is the first step you can test right now?"
Ask for a second valid solution, then compare efficiency, clarity, or number of steps.
Offer the printed hints only when the learner reaches a specific sticking point.
Change the response route or page presentation while keeping the learning goal visible. This support choice is not a diagnosis, placement decision, or permanent learner label.
Use this page as practice evidence and conversation support, not as a diagnosis, placement test, or standalone grade.
When Runner Reflex Arrow Code is finished, save one reflection and a sensible next step. This connects offline practice with recent game and guided-session activity.
