Addition grids (adding hundreds to a 3 digit number) WORKSHEET DESCRIPTION
These addition grids enable children to understand the commutativity of addition as they find the sum of numbers at the top of each column and start of each row.
Pupils will find the sum to two numbers, one a multiple of 100 and one three-digit number. The worksheet begins with adding two numbers that are both multiples of one hundred and progresses to adding a multiple of one hundred to a number such as 445. There are 36 questions to answer in total.
All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions
Your child will develop their understanding of adding multiples of 100 to three digit numbers, which is a key skill at this stage. The grid format helps them see that addition works the same way regardless of which number comes first - this is called the commutativity property. They'll build confidence with larger numbers whilst reinforcing that adding hundreds follows the same patterns they already know.
