Addition Number Pyramids – 3 Rows

Print addition pyramids of three rows: three bricks at the base, two above them and one at the top, each the sum of the pair below. With small numbers, up to 9 at the base and 36 at most at the top, they are the first step into number pyramids.

Twelve pages give the whole base, so the child adds pairs upward; twelve more print only three bricks here and there, and some must be found by subtraction. Six pyramids fill each page, and the set prints as one workbook.

Three Bricks to Start With

A three-row pyramid asks for only three answers: two sums on the middle row and one at the top. That makes it the right size for a first try, and six of them on a page give enough practice for the method to stick.

Small Numbers, Quick Facts

Base numbers stay between 1 and 9, so the middle bricks reach 18 at most and the top 36: addition facts within 20, then one two-digit sum per pyramid.

When Only Clues Are Given

On the second half of the set, three bricks are printed and the other three must be found. A brick above two known ones is their sum; a brick under a known one is that brick minus its neighbor.

Frequently Asked Questions

What Grade Are Three-Row Addition Pyramids For?

First and second grade: the base numbers practice sums within 20, and the top brick, at most 36, brings in a small two-digit addition. Older children use them as a quick warm-up.

Why Are Some Bricks Already Filled?

On pages N13 to N24, the clues replace the full base: three bricks are given, never the whole bottom row, and they are chosen so that the pyramid can be finished one brick at a time.

Can a Base Brick Be Found From the Top?

Yes. Take the top brick and subtract the middle brick on one side: the result is the middle brick on the other side. Do the same one row lower to reach the base. Working down is what the sheets with scattered clues practice.
