Practice and check
Worked example
Rotate the whole model clockwise by the shown angle. Shade the resulting cells in the blank grid.
↻ 90° → 1, 4 → 1, 4
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Rotate the whole pattern clockwise, not each cell separately. Keep the number of black cells unchanged.

- 2. ↻ 90° → 2, 4 → 2, 4
- 3. ↻ 90° → 3, 6, 8 → 3, 6, 8
- 4. ↻ 180° → 1, 5, 6 → 1, 5, 6
- 5. ↻ 270° → 2, 5, 9, 16 → 2, 5, 9, 16
- 6. ↻ 270° → 4, 7, 10, 14 → 4, 7, 10, 14
- 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.
