Matrix rules
Strategy card
In a picture grid, each row and column follows a rule.
- Step 1: Look across the first row. What changes?
- Step 2: Look down a column. What changes?
- Step 3: Use both rules to fill the empty box.
- Step 4: Check your answer in its row AND its column.
Tip: Check both directions: across and down.
Worked example
Which figure completes the matrix?
- A: outlined yellow star
- B: yellow star (the answer)
- C: yellow square
- D: striped yellow heart
Why: Each column keeps its own fill (outlined, solid, left to right). Each row keeps its own shape (square, star, top to bottom). So the missing figure is the yellow star.
