Grade 5 Addition Worksheets
Grade 5 takes addition beyond whole numbers. Children add decimals to tenths and hundredths, add large whole numbers, and add fractions with different denominators, simplifying their answers. Every sheet has 20 questions and an answer key.
What is on each sheet
- Easy: Adding decimals to tenths. A confidence builder that practises the core skill on its own.
- Medium: Hundredths and large whole numbers. One new step, so children stretch without getting stuck.
- Hard: Fractions with unlike denominators and decimal word problems. The last four questions are short word problems that ask children to choose the sum themselves.
Each worksheet prints on one A4 page with space to work, followed by a separate answer key page. Print only the first page for the child and keep the key for checking.

How to use these sheets
- Start with the easy sheet and do not rush: accuracy first, speed comes later.
- Check with the answer key together and ask your child to redo any wrong answers, explaining each step out loud.
- Move up a level after 18 or more correct answers. If a level feels too hard, make a new sheet at the level below.
- Keep sessions short. Ten focused minutes a day builds fluency faster than one long session a week.
Frequently asked questions
How do you add decimals?
Line up the decimal points, fill empty places with zeros (3.4 becomes 3.40), then add as normal and keep the point in line.
How do you add fractions with different denominators?
Rewrite both fractions with a common denominator, add the numerators, and simplify the result.
