Living or Not Living?

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 animal groups?" Then let them work through the worksheet on their own or with a partner, 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 animal groups 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.

These animal groups worksheets for 1st grade give students a clear, visual way to work through one of the big ideas in animals. 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 animal groups accurately. Working through animal groups on paper gives 1st grade students something concrete to hold onto before, during, or after the hands on part of a lesson.

This worksheet is designed for 1st Grade students (Ages 6-7), aligned to NGSS standard 1-LS1-1. It can also be used as review for early students at the next grade level or as an introduction for advanced students.

Yes. This worksheet works for homeschool, classroom, and tutoring settings. Print individual pages for targeted practice, or print the full set as a packet. Works great as a morning warm-up, independent center activity, or fast-finisher task.

The test at this age is three questions: does it grow, does it need food or water, and does it make more of itself. A tree passes all three even though it does not move, which is the point most children need to meet early.

Because it never grows, never eats and never makes a baby. Children often sort by "does it look like an animal", so a picture that looks alive but is not is the useful case to argue about.

Plant, Animal or Thing? takes the same pictures and splits the living group in two. Sorting living from non-living first, then plant from animal, is easier than doing both at once.

First graders learn to sort animals by shared traits like body covering, how they breathe, and whether they are warm- or cold-blooded. They practice placing familiar animals into groups such as mammals, birds, fish, reptiles, and amphibians. This builds early classification skills that are central to science thinking.

Animal classification is a core part of Grade 1 life science and is typically taught during an animals unit in the fall or winter. It connects to NGSS standards on organism diversity and is often paired with sorting games and picture cards.

Play an animal sorting game at home using toy animals, picture books, or a nature magazine. Ask your child to sort them into groups and explain why. Then use the worksheets to check and reinforce what they've figured out on their own, the combination of play and practice deepens understanding.
