Free Printable Number Pyramids
Print number pyramids, also called number walls: rows of bricks that narrow to a single top, each brick worth the two beneath it combined, by addition or, in the multiplication sets, by multiplication. Children fill the empty bricks by working upward from the base, or up and down from a few given ones.
Each set focuses on one operation and one height: addition pyramids of three, four or five rows, and multiplication pyramids of the same heights. Half of every set prints the whole bottom row; the other half scatters as many clues as there are rows, so subtraction or division comes in as well. Every page holds six pyramids, and each set comes as a workbook.

About the number pyramids
How a number pyramid works
Picture a stack of bricks that loses one brick on each row up to the top. In an addition pyramid, a brick holds the total of the pair it rests on; in a multiplication pyramid, their product. With the bottom row complete, the whole pyramid follows from it, row after row.
Going up and coming down
When only a few bricks are printed, the child works in both directions. Going up, two neighbors give the brick above them. Coming down, a brick and one of the two under it give the other one: by subtraction in an addition pyramid, by division in a multiplication pyramid. The clues are always placed so that some brick is decided by two known ones.
Choosing a set
Begin with three rows of addition and a full base, then add rows, then try the sheets with scattered clues. Multiplication pyramids follow once the times tables are known; their numbers grow fast, up to four digits at the top of five rows. Each sheet holds six pyramids, a good length for a lesson or a homework slot.
Other names
Teachers in German-speaking schools know them as Zahlenmauern, number walls, and many English worksheets call them addition pyramids or sum pyramids. Whatever the name, they turn a page of calculations into a puzzle with a single correct way to fill every brick.
