How to use this worksheet
- In the top-left puzzle, the top row shows a square, a triangle and a star, so the last square needs the circle.
- That puzzle's second row is completely empty; solve the columns and boxes around it first.
- In the bottom-right puzzle the fourth column is already full, a clue for every row it crosses.
What this worksheet teaches
Each puzzle is a 4×4 grid divided into four 2×2 boxes, and every row, column and box must contain each shape once. With only 8 shapes given instead of 10, children can no longer finish a row just by looking along it; they have to combine information from a row, a column and a box. Holding two or three facts in mind at once makes this level a real stretch for preschoolers. Each puzzle has exactly one solution.
Three checks for every square
Before drawing a shape, ask three questions: is it already in this row? In this column? In this box? A shape that passes all three checks may go in the square. If only one shape passes, it must go there. Saying the checks aloud helps children slow down and avoid guessing.
