Frequently asked questions
What is a number pyramid?+
A number pyramid (or addition pyramid) is a triangle of bricks where each brick equals the sum of the two bricks directly below it. You're given the bottom row and add your way up to the single brick at the top.
How do you solve a number pyramid?+
Start at the bottom. Add each neighbouring pair to fill the brick that sits between and above them, then repeat with the new row, until you reach the top brick.
Why are number pyramids good practice?+
They pack lots of addition into one puzzle and reward careful, step-by-step work. Because every brick depends on the two below it, a single mistake shows up higher in the pyramid — which helps children learn to check as they go.
What ages are they for?+
Three-row pyramids suit early adders (around ages 6–7), four rows fit Grades 2–3, and five-row pyramids make a fun challenge for confident students.
