Practice and check
Worked example
Read each row left to right. Find how the first two patterns relate to the last, then check the other complete row. Turn clockwise by the same angle at each step of a row. Infer the angle from the complete rows.
1. Turn clockwise by the same angle at each step of a row. Infer the angle from the complete rows. 90° → F
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Turn clockwise by the same angle at each step of a row. Infer the angle from the complete rows. Check every black cell. Use a rule that fits both complete rows, rather than choosing by resemblance.
- Infer clockwise turns of 90°, 180° or 270° from the two complete rows. Black cells move together; the operation does not combine patterns.

Tips for Parents
What is on the sheet Find the rule in the two complete rows. Choose A–F for ? and write one letter. Infer clockwise turns of 90°, 180° or 270° from the two complete rows. Black cells move together; the operation does not combine patterns. Original practice activities, not a standardized test or IQ score. Steps describe the task, not an age or ability grade.
