Grade 3 math worksheets — questions teachers ask
What math topics do the Grade 3 worksheets cover?
Operations & Algebraic Thinking, Number & Operations in Base Ten, Number & Operations — Fractions, Measurement & Data and Geometry — the Common Core domains taught in Grade 3. That is 133 worksheets across 25 standards, grouped on this page by the standard each one practices rather than by topic name, so a sheet can be matched to the code you are teaching to.
How many free Grade 3 math worksheets are there?
133, each one practicing a distinct sub-skill rather than repeating a sibling under another title. Every sheet is published in 25 versions, so Grade 3 has 3325 printable papers in total, all free and all with an answer key.
What age are Grade 3 math worksheets for?
Grade 3 is typically ages 8-9 in the United States. The sheets are grouped by Common Core standard rather than by age, so a student working above or below their grade level can be given the sheet that matches the standard they are on.
Do the Grade 3 worksheets include answer keys?
Every one. The key is generated from the same problems as the questions and prints on its own sheet of paper, after them, so it does not go out with the class. That holds for all 25 versions of every Grade 3 sheet, not only the first.
How do I give each student a different Grade 3 worksheet?
Open any sheet and pick a set number from 1 to 25, or download set 1's class PDF, which contains all 25 versions in one file. The problems are fixed to each address, so the key you photocopied on Monday still matches on Friday.
Are the Grade 3 worksheets really free?
Yes. Every Grade 3 worksheet, answer key and PDF here is free to print and photocopy for your class. There is no account, no email capture before a download, and no sheet that turns out to need a subscription at the last step.
Are there Grade 3 lesson plans as well as worksheets?
25 of the 25 Grade 3 standards on this page have a full lesson plan written — timed section by section, with the exact wording where it matters, the misconceptions to expect and an exit ticket. Each one is linked beside its standard above.
