The big idea
Grids usually change one feature across rows and another down columns. Find both rules and combine them.
Tips that save marks
Check both the row AND the column.
Diagonal patterns sometimes appear in 3×3 grids.
Now try five
Try each one before you look at the answer: answering from memory is what makes it stick. Tap an option to check it. Most children get three or four right at first; five out of five means move on to the next topic.
