These triangle templates are downloadable PDFs optimized for 8.5” x 11” letter-sized printing, making them convenient for standard home or school printers. The possibilities are endless with triangle templates for kids, from creating greeting cards to teaching geometry. They can be used to trace and color, teach fine motor skills, label angles, trace lines, and write number sequences along each edge. Triangles are also used in art, creating confetti, mosaic pictures, and math puzzles. To stay organized, create a printable binder or folder with each size of triangle template clearly marked and save each PDF file in a dedicated “Shapes” folder.
Explore the Creative Joy of Triangle-Themed Printables
Discover the Fun of Triangle Crafts with Colorful Explorers
As a parent, teacher, or creative soul, there’s something magical about introducing children to the world of shapes—especially through the use of free, printable, and easy-to-use triangle templates. At Colorful Explorers, our passion lies in bringing learning and creativity together in a fun way, and our triangle templates collection is a great example of that. These printable triangles range in sizes from 1” to 7.5”, and can be used for everything from classroom projects to rainy day craft activities.
If you’re already a fan of our camping coloring pages, you’ll love this geometry-inspired adventure! Much like a triangle-shaped tent in the wild, each triangle on paper becomes a doorway into imaginative drawing, coloring, and hands-on crafting. Let’s dig into the triangle world, where each angle, line, and point has its own story.
Endless Possibilities with Triangle Templates for Kids
At Colorful Explorers, we’ve created a collection of triangle templates that come in different sizes and designs to match any child’s interest or classroom assignment. These printables can be used in various ways, like making greeting cards, quilt designs, or even for teaching geometry. I’ve used them myself while crafting mini booklets with my kids—we cut out triangles, colored them, and glued them on pages to create animals, monsters, and sea life scenes.
Our templates are downloadable PDFs, optimized for 8.5” x 11” letter-sized printing, which makes them convenient for standard home or school printers. Each template can be resized to 50%, 100%, or adjusted for bigger or smaller versions depending on your project. Whether you’re making a mini bunting, a math worksheet, or a themed board game, there’s a triangle here for you.
Want to make it even more special? Try printing on cardstock or colored paper for a sturdier or more vibrant effect. You can even print on sticky-backed paper to turn them into stickers. The possibilities are truly endless.
Shape Up Learning with Triangles
Using triangles to teach children about geometry and mathematical concepts like equilateral or isosceles shapes is both fun and effective. Start with a 1-inch triangle template and have kids trace and color them in rows, helping them practice fine motor skills, pencil control, and tracing. You can ask older children to label the angles, trace lines, and even write number sequences along each edge, from counting backwards to multiples of ten.
Let’s not forget the real-world connection—triangles appear everywhere! From nachos and sandwiches to road signs and camping tents, they’re more than just shapes. When children spot a triangle in the wild, it cements their learning and helps them recognize shapes in the world around them.
One of my personal favorites was creating a sun using a circle template in the middle and yellow triangle flames cut from a 2.5-inch template. We stuck them around the edges with tape, creating a bright, cheerful craft we still have on our fridge today.
Mix Sizes and Colors for Triangle-Themed Art
Let’s talk about creating art. Using a variety of triangle sizes—from 1 inch, 1.5 inch, all the way up to 7.5 inches—lets children explore how different shapes work together. Try using 3-inch triangles as roofs for houses or beaks on birds. Turn 3.5-inch triangles into pizza slices, cheese wedges, or even tiny trees for a Christmas collage.
Here are some creative triangle projects:
- Triangle confetti: Use the smallest triangles (like the 1-inch or 1.5-inch) to cut out dozens of colorful pieces and scatter them on a card or around a party banner.
- Mosaic pictures: Use 2-inch and 2.5-inch triangles in different colors to form animal shapes, abstract art, or even recreate flags.
- Math puzzles: Use 4-inch triangles in different colors and ask your child to form a larger triangle, helping with problem solving, logic, and spatial recognition.
Triangles in Crafts, Decoration, and More
I often use 4.5-inch and 5-inch triangles with my kids to make holiday decorations or themed crafts. We use green felt, gold stars, and glitter to turn triangles into Christmas trees and baubles. Add a looped ribbon at the top, and voila—a ready-to-hang ornament for the classroom or home.
The 5.5-inch and 6-inch templates are great for stencils, design sketches, and pattern planning. Print them on white paper or outline sheets and invite children to fill in patterns using paint, crayons, or felt-tip pens.
Want something a bit more advanced? Fold a 6-inch triangle and turn it into an origami heart—perfect for Valentine’s Day crafts. Or stitch together 6.5-inch triangle templates made from fabric to create bunting for birthday parties or summer fairs. Just fold the top edge over some string or ribbon, glue it down or stitch, and you have an instant party piece.
For older kids or larger-scale art, the 7-inch and 7.5-inch triangles can be used to design traffic signs, educational diagrams, or as a base for chalkboard signs. I’ve even used the 7-inch size to help my kids make their own flags to wave during international day at school.
Organizing and Storing Your Triangle Printables
To stay organized, I recommend creating a printables binder or folder with each size of triangle template clearly marked. Since each template is available in downloadable PDF format, you can reprint whenever needed without having to save physical copies.
You can also save each PDF file on your computer in a dedicated “Shapes” folder. When you’re ready to use a triangle, just click the file, open in your browser, and hit print. Each file opens perfectly on standard paper and can be resized or rotated for custom needs. That’s how I ensure we’re never scrambling on a busy day to prep for art time!
