Free Y5 maths worksheets: Use known facts to add or subtract mentally

knowChildren still need to develop their addition and subtraction skills in year 5. These two worksheets concentrate on adding a single digit to a number in the thousands; the answer being in the next thousands.

eg 3 997 + 6

They are also asked to explain how they did it. This could be done orally or on paper. A good knowledge of place value is needed so they might explain by saying, “I added 3 to make 4000 then added the extra 3 to make 4003.”

Not as easy as they look, but this kind of addition should be done “In your head” rather than on paper.
