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. Keep only positions black in both patterns.
1. Keep only positions black in both patterns. → C
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Keep only positions black in both patterns. Check every black cell. Use a rule that fits both complete rows, rather than choosing by resemblance.
- Keep only positions black in both patterns. Step 1 uses sparse patterns, step 2 adds overlap, and step 3 uses denser patterns. The incomplete row changes too.

Tips for Parents
What is on the sheet Find the rule in the two complete rows. Choose A–F for ? and write one letter. Keep only positions black in both patterns. Step 1 uses sparse patterns, step 2 adds overlap, and step 3 uses denser patterns. The incomplete row changes too. Original practice activities, not a standardized test or IQ score.
