KS1 addition worksheet that helps Year 1 and Year 2 children practise mental addition by stacking number bricks.
An addition wall is a pyramid of bricks where each brick holds the sum of the two bricks directly beneath it. Children read the partial walls on the page, work out the missing bricks by adding pairs together and fill them in. The walls start small to build confidence, then introduce missing bricks at different levels so children practise both forwards (working up from the bottom) and backwards (working out a missing bottom brick from the total above).
Useful for KS1 mental maths warm-ups, homework or classroom intervention on number bonds. Find more addition practice in our addition worksheets for KS1 ages 5 to 7. Printable PDF, A4, downloads instantly after purchase.
