Build-a-Heart Pattern Block STEM Challenge for Preschool

This Valentine’s Day, I decided to create a Valentine’s Day pattern block STEM challenge for my kids. In this version of our Valentines STEM activities, I asked my kids to make as many heart shapes as they could using pattern blocks.

Even though the challenge sounds easy, once you start working with the pieces, you realize it’s harder than it sounds!

My kids spent about an hour trying to make various heart shapes using standard pattern blocks.

If you love Valentine's Day and also math, then you'll have a blast with the pattern block hearts challenge! It's the perfect way to make geometry fun.

The kids tried a lot of different designs. I was surprised at how many ways there are to make hearts!

How to Make a Heart Out of Pattern Blocks

We stuck to 2D designs for this particular challenge, but you could easily use your pattern blocks to make 3D hearts as well.

The more blocks you use while making hearts, the harder it is to keep the heart shape.

The girls had a lot of fun trying to see which blocks could mimic the rounded shape of a heart.

They quickly discovered that some designs you think are going to work, but they don’t.

And shapes you think won’t work, sometimes are the right piece you are looking for!

I was happy to see my kids using the pattern blocks in this way.

This activity helps build spatial awareness, logic, critical thinking, and math skills all in one.
