Animal classification
Written by Adi Ackerman, Head Teacher
"Animal classification" is written for 3rd Grade (Ages 8-9), and it covers NGSS 3-LS4-3. NGSS has no dedicated standard for animal taxonomy at 3rd grade. 3-LS4-3 is the nearest fit, since the body coverings and traits used to sort animals also relate to the environments they live in. If your little one is a year younger but already steady on living things, the page still works. You may just need to read the instructions out loud. And if they are older and classification of living things never quite stuck, this is a short review rather than busywork.


Free printable animal classification worksheet for 3rd grade students. Part of our classification of living things living things collection. Aligned to NGSS standards.
How do I use this worksheet?
Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about classification of living things?" Then let them work through it independently, using a partner or small group only if they want to talk through their thinking, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These classification of living things worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.
What students will practice
- Sort living things into groups based on shared physical characteristics
- Identify the major kingdoms of life and provide examples of each
- Explain why scientists use classification systems to study living things

What does this worksheet teach?
⌄
These classification of living things worksheets for 3rd grade give students a clear, visual way to work through one of the big ideas in living things. Students label diagrams, sort and classify examples, read short explanations, and answer questions that ask them to say why, not just what. Each page keeps the science vocabulary front and center so students leave with the words they need to talk about classification of living things accurately. Working through classification of living things on paper gives 3rd grade students something concrete to hold onto before, during, or after the hands on part of a lesson.
Can I use this classification of living things worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 3rd Grade living things, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with classification of living things. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
What does classification of living things teach third graders?
⌄
It teaches students that scientists organize living things into categories based on shared characteristics. Third graders learn to distinguish between plants, animals, and other organisms, and begin to recognize subcategories like mammals, reptiles, and insects. This skill builds critical thinking and observation habits.
When do third graders learn classification of living things?
⌄
This topic is typically introduced in Grade 3 life science units, often at the start of a unit on living things or ecosystems. It lays the groundwork for later learning about food chains, adaptations, and ecosystems. Most 8-9 year olds are ready to sort and categorize using observable traits.
How can I use these worksheets at home?
⌄
Use the worksheets to spark conversations during walks or nature visits, ask your child to sort animals they see into groups. The sorting and labeling activities reinforce vocabulary without feeling like homework. Even 10-15 minutes of focused practice builds confidence for classroom tests.
How many 3rd Grade classification of living things worksheets are there?
⌄
9 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.
What age are classification of living things worksheets for?
⌄
These are written for 3rd Grade students, roughly ages 8-9. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Are these classification of living things worksheets aligned to NGSS?
⌄
Yes. Each one shows the NGSS code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
Can I use these classification of living things worksheets for homeschool?
⌄
Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 3rd Grade classroom, a literacy centre, or a tutoring session.
