Practice and check
Worked example
Move every black cell by the indicated arrows and counts. Each count is one cell; do not rotate or wrap around.
1, 4; → 1 → 2, 5 → 2, 5
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Move every black cell by the same displacement without rotating, reflecting, or wrapping around.
- (r,c) → (r+Δr,c+Δc) · Step 1: →1 / ←1 · Step 2: ↑1 / ↓1 · Step 3: ↓1 ←1 / ↑1 →1

- If an answer differs, return to the first step that differs and explain the choice. Change the answer after checking rather than guessing a new rule.
- Try the next step when the current method feels manageable. You may repeat a problem, use a paper marker, or stop and return later.
- Original practice activities, not a standardized test or IQ score. Steps describe the task, not an age or ability grade.
