Pattern Block Christmas Tree Sensory Bag for Preschool

If you love Christmas, you’ll love this fun sensory-friendly and STEM activity-oriented Christmas pattern block sensory bag! Once Christmas rolls around, we are all about that hands-on Christmas STEM activity list, and this year we added a sensory element to our Christmas tree STEM activities with this Christmas tree sensory bag.

It was a lot of fun making this bag, and it was so easy to do, too!

All you need to bring this bag to life is some pattern blocks, hair gel, and a bit of imagination!

Make Christmas a fun sensory activity and math rolled into one with this Christmas pattern block sensory bag! Preschoolers will love this STEM activity!

Here is how to bring STEM into the holiday season for even the youngest kids!

Bring STEM to Life with a Pattern Block Sensory Bag

Scroll down to get the directions to make your Christmas tree pattern blocks, but first, make sure you have everything you need to teach the lesson to preschoolers from the right materials to the right supplements.

Keep scrolling to the bottom of the post to find out how to make your own Christmas pattern block sensory bag and the benefits of STEM activities for preschoolers during the holiday season.

Why Should I Include Pattern Blocks in My Preschool Classroom?

Preschoolers can learn a variety of valuable skills and concepts through play with pattern blocks.

These colorful geometric shapes offer a hands-on and engaging way for young children to develop their cognitive, mathematical, and spatial skills.

Here are some of the key things preschoolers can learn through pattern block play:

Shapes and Geometry

Pattern blocks introduce preschoolers to basic geometric shapes, such as triangles, squares, rhombuses, hexagons, and trapezoids.

Preschoolers can learn to identify, name, and differentiate between these shapes.

Spatial Awareness

Manipulating and arranging pattern blocks helps preschoolers develop spatial awareness and an understanding of how shapes can fit together to create larger designs.

This is a fundamental skill for learning geometry and problem-solving in the future.

Fine Motor Skills

Handling and manipulating the small pattern blocks can enhance fine motor skills for preschool children.

Preschoolers practice hand-eye coordination as they pick up, position, and fit the blocks into patterns.

Mathematical Concepts

Pattern block play introduces mathematical concepts such as symmetry, congruence, and symmetry transformations (e.g., flips, slides, and rotations).

Preschoolers can explore these ideas by creating symmetrical designs and matching shapes.

What Can Preschoolers Learn with Sensory Bags?

Playing with squishy textures, such as this Christmas tree sensory bag, can be a fun and sensory-rich experience for preschoolers.

Sensory bags provide learning and development in various areas, including sensory awareness, fine motor skills, and gross motor skills.

Here’s what preschoolers can learn through play with sensory bags:

Sensory Exploration

Squishing, squeezing, and manipulating squishy textures allow preschoolers to explore their sense of touch and tactile sensations.

Preschoolers learn about different textures, temperatures, and consistencies, which enhances their sensory awareness.

Motor Skills

Squishing and manipulating squishy materials like playdough, slime, or sensory balls helps preschoolers develop their fine motor skills.

Pinching, rolling, and shaping these materials require hand and finger coordination, which is important for tasks like writing and drawing.


Exploring squishy textures often involves solving challenges, such as figuring out how to shape a specific form or how to make textures stick together.

Basic Math

Squishy play can incorporate basic math concepts.

For example, children can compare the sizes of different squishy shapes, count the number of pieces they have, or divide squishy materials into equal parts, introducing early math skills.

Scientific Inquiry

Exploring the properties of squishy materials can introduce basic scientific concepts such as changes in shape, texture, and state of matter.

Children may experiment with how squishy materials behave under different conditions (e.g., temperature changes).

Christmas Pattern Block Sensory Bag Set Up

The easiest way to introduce this Christmas pattern block lesson to preschoolers is to have everything set up in advance.

For this Christmas pattern block sensory bag, the math element is at a basic level for preschoolers.

Kids learn a lot about spatial awareness that helps develop a stronger grasp on geometry, problem solving, and pattern-making skills.

But you can also use the Christmas sensory bag to solve simple math problems, count, write numbers, and tons of other activities!

We also learned that if you don’t want to use hair gel to make your Christmas tree pattern block sensory bag, you can instead use hand sanitizer.

It won’t have quite the same feel, but it’s easier to clean up if the bag happens to get opened.

And if you’re looking for another preschool-friendly Christmas STEM activity, my preschooler loved following these directions on how to make your own snow globe.

What You Need to Make a Christmas Tree Sensory Bag

Here are the supplies you’ll need to make your Christmas sensory bags.

What liquid do you put in a sensory bag?

We like to use hair gel for our Christmas sensory activity, but you can also use hand sanitizer or even clear glue when creating a Christmas pattern block sensory bag.

Hands-On STEM Resources about Trees

Here are some hands-on STEM resources about trees that can be used alongside this Christmas tree STEM activity.

Step by Step Directions to Make the Christmas Tree Sensory Bag STEM Activity

Before you make a preschool or toddler Christmas tree sensory bag, decide what your activity will be. We decided to make a Christmas tree design and then see if the kids could replicate it inside the bag.

But if you want to do another math activity, like addition or subtraction, just add in as many pieces as you need, and the math symbol borrowed from a set of magnetic numbers.

Put the gel in the bag first, then add the pattern blocks.

Make sure you seal the bag tightly, you do NOT want a bunch of hair gel loose in the classroom or in your house.

Push any extra air out of the bag to make it easier to move the pattern blocks around.

Show the kids how they can move things around to decorate a Christmas tree sensory bag, and let them go crazy!

Books about Christmas Trees

These science books about evergreen trees will be a good addition to any Christmas tree STEM project!

Pattern Block Christmas Tree Preschool Lesson Plan

Prep Time: 15 minutes
Active Time: 30 minutes
Total Time: 45 minutes
Difficulty: easy
Estimated Cost: $10

Enrich your preschooler's holiday experience with a touch of mathematics! Use this Christmas tree sensory bag lesson plan to combine learning and fun.


  • Green hair gel (or dye clear gel with food coloring)
  • Plastic pattern blocks
  • Ziploc bags (we used gallon size)
  • Glitter (optional)


Here is a lesson plan to go along with your pattern block Christmas tree sensory bag.

Introduction (5 minutes):

Tell your preschoolers how they will make Christmas trees using special pattern blocks and a squishy sensory bag filled with hair gel.

Activity (10 minutes):

Distribute pattern blocks to each child, making sure they have a variety of shapes and colors to work with.

Encourage students to create their own Christmas tree design using the pattern blocks on a flat surface or table. They can arrange the blocks to form the tree's branches, ornaments, and decorations.

Take a Ziplock bag for each child and add a generous amount of hair gel inside. If you want, you can add a few drops of green food coloring to make it more festive.

Have the preschoolers drop their pattern blocks into their gel bags. Seal the bag tightly and double-check for any leaks. Double seal the bags with clear tape.

Invite students to squish and move the pattern blocks in the bag to recreate their Christmas tree designs.
