Number pyramids — add your way to the top

Number pyramids turn a page of additions into a puzzle with a goal: reach the top. Each brick is the sum of the two bricks under it, so children add again and again without the boredom of a plain list. The last level hides bricks anywhere in the pyramid, and that changes everything: to find a lower brick, children must subtract — a natural way to see that addition and subtraction undo each other. Every pyramid with missing bricks has been checked to have exactly one solution.

How to get the most from these sheets

• Show one brick and its two “feet”: top = left foot + right foot.
• Work from the bottom up, row by row.
• For missing bricks, look for a group of three where two are known.
• Check the top: it should match when you add up again.
