Sudoku puzzles
Logic grids with no arithmetic: fill each row, column and box with every shape or number once, with one solution for each puzzle.
About this worksheet
Students fill a small grid so that every row, column and box holds each symbol exactly once. The 3×3 and 4×4 grids can use simple shapes (circle, square, triangle and plus sign) that children can draw, which makes them a first logic puzzle for kindergarten and first grade. Numbers on 4×4 and 6×6 grids suit older students.
Every puzzle has exactly one solution. Choose most squares given for a gentle start, or the fewest squares for a real challenge.
Printing
US Letter or A4, portrait: choose your paper size above. Print at 100 percent (actual size). Use "Black and white" for the copier, or "Color" for display pages and mini books.
