Read each row left to right. Find how the first two patterns relate to the last, then check the other complete row. Keep every position black in either of the first two patterns.
1. Keep every position black in either of the first two patterns. → B
Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
Keep every position black in either of the first two patterns. Check every black cell. Use a rule that fits both complete rows, rather than choosing by resemblance.
Keep every position black in either of the first two patterns. Step 1 uses sparse patterns, step 2 adds overlap, and step 3 uses denser patterns. The incomplete row changes too.

What is on the sheet
Find the rule in the two complete rows. Choose A–F for ? and write one letter. Keep every position black in either of the first two 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. Steps describe the task, not an age or ability grade.

Choose the next step
Keep every position black in either of the first two patterns. Step 1 uses sparse patterns, step 2 adds overlap, and step 3 uses denser patterns. The incomplete row changes too. Try the next step when the current method feels manageable. You may repeat a problem, use a paper marker, or stop and return later.
