Adding and subtracting decimals to hundredths
Work with tenths and hundredths, then solve money and measurement problems. Line up place values and estimate first to check whether each answer is reasonable.
Worked example: 3.45 + 2.38 = 5.83: 345 hundredths + 238 hundredths = 583 hundredths.

A zero can hold a place: 8.2 is the same as 8.20. Ask learners why aligning decimal points preserves the value of each digit. The sample does not cover the whole-number portion of the expectation.

These samples were generated with PracticeNest’s worksheet pipeline and checked for arithmetic and page layout. They have not been reviewed by a classroom teacher. Review the questions for your learners before use.
Make a fresh version for your class. We carry the grade, math topic and province into setup; you can review the request before generating. A free account includes 5 sheets per month, with Word and Google Docs export.

Match the topic to what your learners have studied. A focused worksheet covers part of a curriculum, not an entire grade. Review generated content and its expectation references before sharing it with your class.
What can you generate for Grade 5?
These are examples, not a fixed catalogue — you can ask for any topic at this level, in your own words:
- addition and subtraction to hundredths
- multiplication facts to 12×12
- fractions with like denominators
Each sheet arrives with clear instructions, a full answer key on a separate page where answers are definite. Check any generated curriculum citation against the current official source.
How do you make Grade 5 math worksheets fast?
Set your class to Grade 5 and Ontario once. From then on, describe what you are teaching — “addition and subtraction to hundredths, one page” — and you have a finished, curriculum-aligned sheet in about 30 seconds. If it is not quite right, ask for a change in plain language and it regenerates.
For a mixed-ability class, one click produces below-grade, at-grade, and above-grade versions of the same sheet, generated together and laid out identically. See how it works →
