Grade 3–4 worksheets

Printable worksheets for 9- and 10-year-olds — designed for the years when logical reasoning, multi-step problem solving and reading-between-the-lines really take off.

What's inside (ages 9–10)

• Sudoku 6×6

  Mid-complexity logic grids — constraint reasoning at school-age pace.

• Raven's matrices

  Visual pattern completion — fluid reasoning without language load.

• Magic squares

  Find the missing number so every row, column and diagonal sums alike.

• Cipher decoding

  Crack a shift cipher — symbol-system reasoning and alphabet fluency.

• Reading inference

  Short passage + questions that need reading between the lines.

• Deduction grids

  Logic-puzzle clues that narrow down who, what and where.

Why these activities work for Grade 3–4

By 9–10, kids can hold multiple constraints in working memory and reason about rules, not just patterns. Sudoku, magic squares and Raven's matrices stretch fluid reasoning; cipher decoding and reading-inference activities train the abstract, symbolic thinking that middle school will lean on. Every sheet is freshly generated so the puzzle is genuinely new each print.
