Free Printable 3rd Grade Worksheets

Sometimes, you need one helpful worksheet. Not ten. Not twenty. And certainly not a whole page of links.

These free printable 3rd grade worksheets contain six unique activities for math, reading, grammar, writing, science, and social studies, plus answer keys, teaching tips, and a week-long plan.

Use them for extra help, lessons, homework, and summer practice. You’ll start with one simple activity and see how the child responds. A worksheet is a diagnostic tool, not a race to the bottom of the page.

The activities cover typical U.S. Instead of trying to complete every problem, pick one or two skills that the child needs to practice.

How to Print These Worksheets or Save as a PDF File

These are copy-and-print activities, not PDF pages to be filled online.

1. Copy the worksheet you want into Word or Google Docs.
2. Keep the answer key on a separate page.
3. Add space for writing, and use a big font, like Times New Roman 12 pt or Arial 14 pt.
4. Print the document on Letter or A4 paper after previewing it.
5. To save as a PDF file, go to Print > Save as PDF.

Black and white is fine, but some worksheets require coloring, so consider spacing before reducing the font size. Print a test page to see how the questions fit on a single sheet. Another option: print one page for the student and a separate page for your notes.

What Should 3rd Graders Know?

Children in 3 rd grade are often expected to explain an answer and defend an opinion. Common math skills include:

• Multidigit addition and subtraction
• Multiplication and division facts
• Fractions as equal parts and numbers on a line
• Area, perimeter, time, measurement, and graphs

Reading comprehension and writing often involve identifying main ideas, describing characters, making inferences, and using text evidence. Note that not all skills will be familiar, and math facts are best reviewed in context. If a third grader is not yet confident with fractions or elapsed time, try explaining or saving those problems for another day.

Worksheet 3: Read, Think, and Explain

Name: ____________________ Date: ____________________

Read the story. Then answer the questions using details from the text.

The Windy Garden

Maya’s class planted bean seeds next to the school fence. Each group watered their pot and measured the seedlings every Friday. Maya’s plant had grown straight, but on the weekend, a strong wind bent the stem.

“I think it is dying,” said Maya.

Eli pointed to two new leaves. “It is growing. Maybe we need to stake it.”

Their teacher helped them insert a slender stick alongside the stem. Maya tied the stem loosely to the stake with cotton thread. She also began checking the soil before adding water. On Friday, the seedlings had grown 3 centimeters.

We needed to observe closely and make a change.”

Comprehension questions:

1. What happened to Maya’s plant after the weekend windy weather?
2. What detail showed Eli that the plant was still growing?
3. What items did Maya and her teacher use to support the plant?
4. Why might Maya have felt the need to examine the soil before watering the plant? Use evidence from the story.
5. What is one thing Maya learned she could do differently in the future? U

Reading comprehension tip: Ask the student to read the passage twice. First, for understanding, then to locate specific details. If you are reading aloud, this is a listening comprehension activity, not an independent reading task.

Third Grade Grammar and Writing Worksheets

Worksheet 4: Fix, Choose, and Explain

Name: ____________________ Date: ____________________

Read each sentence. Make corrections and explain your choices.

1. Rewrite this sentence correctly: on tuesday maya planted beans
2. Choose the correct word: The birds (sing / sings) outside my window.
3. Write the past tense of jump. __________
4. Write a sentence combining these two sentences using because :

I took a coat.

It was cold.

6. Read this sentence: “The path was narrow, so we walked in a single line.”

Does narrow mean wide or not wide?

Teaching tip: Each sentence fixes only one grammar issue. A student who notices both capitalization and punctuation errors will likely become frustrated. .

Worksheet 5: Build a Short Opinion Paragraph

Name: ____________________ Date: ____________________

Writing prompt: Should our class grow a small garden?

Write a 5-sentence paragraph stating your opinion. You may agree or disagree.

Use this plan:

• Opinion statement
• First reason
• Example or explanation
• Second reason
• Concluding thought

Sentence starters:

• I think our class should…
• One reason is…
• For example…
• Another reason is…

Checking guide:

• Did I state my opinion clearly?
• Did I give two reasons?
• Did I explain my reasons well?
• Does my paragraph make sense?
• Did I check my capitalization and punctuation?

Let’s make it easier: Have the child read the paragraph aloud first, and write down the draft. Or, provide a notepad for jotting down ideas before writing the final version.

Let’s add a challenge: Ask the child to mention one opinion and explain why it might be different from theirs. (“Some people might think…, but…”)

A Simple 5-Day Practice Plan

You don’t have to print everything at once. Spread the activities out over the week and make time for stories, games, and free writing, too. Here’s one possible plan:

Monday

Worksheet 1: number skills (10–15 minutes)

Tuesday

Worksheet 3: reading and discussion (15–20 minutes)

Wednesday

Worksheet 2: fractions and measurement (10–15 minutes)

Thursday

Worksheet 4 and a plan for worksheet 5 (15–20 minutes)

Friday

Finish worksheet 5; select two science questions (15–20 minutes)

Use these time frames as a guide. A child who needs more help may benefit from shorter activities and more talking.

Keep one corrected worksheet to show how the child has improved. It’s motivating to see how much practice can help.

How to Help a Child Who Is Struggling With 3rd Grade Worksheets

First, identify the issue. Is the student forgetting facts, misunderstanding the question, or not recognizing the operation? Each problem has a different solution.

• For multiplication or division facts: Practice drawing equal groups or arrays before moving on to written calculations.
• For word problems: Read the question aloud, then act it out or draw a picture.
• For reading: Ask the child to tell you what the story is about. Focus on vocabulary first, then have them answer questions about the plot.
• For writing: Try an oral report or give a sentence starter. If handwriting is causing issues, reduce the amount of writing or let them dictate the response.

Avoid timing and focus on understanding.

Next: Ask the student to explain how they solved the problem. Their answer may be more correct than it appears.

If the child struggles on multiple worksheets, contact their teacher to discuss the issue. Ask for specific feedback so you can support them at home. Share samples of their work if possible. There is no shame in admitting that multiplication is frustrating or that reading takes more time.
