Pearson lists Number Matrix at Levels D–G. Like a visual pattern matrix, a number grid has a missing entry. The student identifies a relationship across a row, down a column, or both and applies it to the blank.
Original learning matrix
| 2 | 5 | 7 |
| 4 | 3 | ? |
Answer: 7. In each row, the first two values add to the third: 2+5=7 and 4+3=7. This is one simple learning illustration, not a publisher item.
How to solve
- Try a simple row rule on the complete row.
- Apply exactly that rule to the incomplete row.
- If the grid has multiple complete rows or columns, verify the rule there too.
- Reject an answer that fits only one cell but breaks another relationship.
