Tips for math puzzles for kids
- In a number pyramid, add upward when you know the bottom row, or subtract downward when you know the blocks above.
- In a cage puzzle, fill the one-square cages first, because the target number is simply the number that goes there.
- In a magic square, start with a line that has only one empty box, then use the magic total to fill it in.
Fun math facts
- In the classic 3 x 3 magic square with the numbers 1 to 9, the center is always 5 and every line adds up to 15.
- Cage puzzles are built on Latin squares, which the mathematician Leonhard Euler studied: every number appears once in every row and column.
- In a three-row number pyramid, the middle number of the bottom row counts twice toward the top, because it feeds both blocks above it.
Fun ways to use your printables
- Let your child design a number pyramid, fill it in, then erase a few blocks and swap puzzles with you.
- Use playing cards from ace to nine to build a magic square on the table, moving cards until each line makes 15.
- Solve a cage puzzle side by side with a friend and compare which cage each of you started with.

Frequently asked questions
What is a math cage puzzle?
A grid where each row and column uses every number once, like sudoku, and thick cages show a target and a sign. The numbers in the cage must make the target with that operation.
Are math puzzles better than worksheets?
They practice the same facts, but kids often do many more calculations because they want to crack the puzzle.
