Free Cells Basic Skills Worksheets for grades 3–5. Cell diagrams can make living units look like empty labeled boxes. Squishling gives each vocabulary word a job, then connects cell structures with single-celled organisms, specialized tissues, growth, repair, and whole-body cooperation.

This six-page packet includes two teacher-guide pages, three student worksheets and an 18-point answer key. Students practice 16 tasks: matching, fill-in, classifying cases, multiple choice and explaining evidence. Print the three student pages; keep the guide and key for instruction. No kit or purchase is required.
Meet Squishling
Gemlings teach science through their personalities and home realms. Squishling guides learners in Cellforge Dome. The character’s teaching note introduces the science mission, and the final encouragement recognizes the student’s learning.
Science topics
- Cells: Small Units of Life
- Cell Parts & Their Jobs
- Plant & Animal Cells
- Single Cells & Organized Bodies
- Cells, Growth & Repair
- Cells Working as a Whole
Simple classroom use
Allow about 20–30 minutes or split the work across lessons. Model the toolbox words and read the case cards aloud when helpful. Students match clues, complete ideas, classify cases and explain evidence. Use the answer key to discuss corrections; accept accurate explanations in a child’s own words. Tasks 1–14 earn one point each and tasks 15–16 earn up to two each.
Compare simple plant and animal cell diagrams with clearly labeled shared structures. Ask students to explain what a membrane does before naming additional parts. Use the organization lesson to build a cell-to-tissue-to-organ sequence.
A science teaching tip
Magnification changes the image, not the cell. Not every plant cell has chloroplasts, and not all cells have nuclei. The packet specifies plant and animal cells when discussing a nucleus.
Train, refresh, then assess
Start with free subject vocabulary training or the free subject reading resource. After worksheet practice, open the subject Adventure page to watch the Gemling video for learning or a refresh, then take the free Online Adventure assessment. The worksheet score is classroom practice, separate from that assessment.
Optional hands-on discovery
Dig Kits can extend Discover–Identify–Collect: uncover specimens, identify them using observations and available specimen/trading cards, and organize a collection. Free worksheets and Online Adventures stand on their own. Teachers may purchase available kits, explore the Free Dig Kits campaign, or ask about possible PTA/PTO funding. Signup does not automatically guarantee free kits; current funding and fulfillment conditions apply. PTA/PTO funding is not guaranteed.
