Under the Sea Graphing Worksheet (3 Free Printables)
When my son was little, math clicked best when it was tied to something he already loved, like the ocean. This free under the sea graphing worksheet turns counting and graphing into a playful activity with sharks, jellyfish, octopuses, and more.
Kids get to color the sea creatures, track how many they find, and then graph the results.
It’s a simple way to practice early math while keeping the activity creative and engaging, whether you’re at home or in the classroom.

Under the Sea Math Worksheets
This free set includes three different count and graph worksheets. Each page has a variety of ocean animals to spot, color, and tally before transferring the results onto a simple bar graph.
Kids begin by coloring in the sea creatures, then counting how many of each they can find. Once they’ve added their numbers to the graph, they answer a few comparison questions like:
- How many of each creature did you find?
- Which one appeared the least?
- Which one appeared the most?
These little questions encourage kids to pause, think critically, and interpret the data they’ve just collected.
What’s Included
The worksheets feature familiar marine animals and details to keep the activity interesting. Children will color and graph:
- Jellyfish
- Sea urchins
- Fish
- Shells
- Crabs
- Coral
- Sea turtles
- Octopuses
- Sharks
Skills Being Practiced
While the activity feels like a coloring page, it’s quietly reinforcing several core skills:
- Counting and graphing – transferring tallies into a bar graph builds early data interpretation skills.
- Observation and comparison – deciding which animal shows up the most or least helps kids organize information and think mathematically.
- Fine motor development – coloring small shapes and writing numbers strengthen hand muscles and pencil control.
- Early science connections – recognizing sea creatures sparks curiosity about marine life while still focusing on math.
Whether you’re working with preschoolers who are just learning to count or early elementary kids who need graphing practice, this set offers a playful way to blend math, coloring, and ocean themes.
