5x5 Calcudoku Puzzles – 4 per Page

Every sheet carries four 5x5 calcudoku grids, the middle size between the first 4x4 puzzles and the 6x6. In each row and in each column, the digits 1 to 5 appear once, and every cage of thick lines shows a target and an operation that its digits must produce.

Three sets of sheets climb in difficulty: addition only, addition with subtraction, and all four operations, where multiplication and division join in. Reasoning alone, with no trial and error, leads to the single solution of every grid, and the book collects all the sheets in a single PDF.

Solving a 5x5 Calcudoku

Single cells first, then the cages with a single way to make their number: two cells adding up to 9 hold 4 and 5, two cells with a product of 20 hold 4 and 5 as well, and a difference of 4 can only come from 1 and 5. The digits 1 to 5 add up to 15 in every row and column, which helps when a row is almost full.

Choosing the Operations

Addition-only sheets train the logic of the grid without any other arithmetic. Subtraction brings in cages of two cells whose digits differ by the number shown. With all four operations, products and quotients join, and a cage's number can hide several combinations, so each deduction asks for a little more thought.

A Compact Format

Four 5x5 grids fit on one A4 sheet, printed in black and white, which makes a set for a week of short sessions or a whole lesson. For larger cells, the 5x5 Calcudoku page puts a single grid on each sheet.

Frequently Asked Questions

Is 5x5 calcudoku harder than 4x4?

A little: there are more cells, the digits go up to 5, and more cages allow several combinations. Children who solve 4x4 grids with ease can move on to it, starting with the addition-only sheets.

Which sheets should I print first?

The addition-only sheets, to get used to the grid; then the sheets with subtraction, and the ones with all four operations once the first two feel easy.
