Math Puzzles

Using puzzles is a great way to learn Math facts and develop mental calculation and thinking skills in a fun and easy way.

Most children are much more engaged and motivated solving puzzles than working out pages of traditional math facts.

Using these math puzzles below will help your child to develop their Math fact skills as well as their strategic thinking and reasoning.

There are different versions of each puzzle from 1st to 5th grade, so it is easy to find an easier or harder version of the same puzzle.

Each puzzle comes complete with answers.

Number Fill in Puzzles

These are all the same format and all work in the same way.

Each 'crossword' type grid contains spaces for numbers - each number that goes in the grid is written below.

The challenge is to use the existing numbers as clues to find out the correct positions of the remaining numbers.

Using these sheets will help your child to:

  • develop logical thinking skills;
  • develop accuracy in reading and writing numbers.
