Pumpkin STEM Challenge Your Preschoolers Will Love

This pumpkin STEM challenge is perfect for your list of preschool pumpkin activities. It’s an incredibly engaging way to explore math and engineering concepts with your students. An added bonus? The pumpkin math fun is such a hit with the kiddos!

Be sure to set a few candies aside with a promise of letting the kids have a few once they finish the activity. Otherwise, you might find a few of the pumpkins mysteriously disappear.

Preschool Pumpkin STEM Invitation

This pumpkin STEM activity might not look like much, but it is an amazing way to explore so many early learning concepts.

Plus, it’s just plain fun and it keeps the kids engaged from start to finish. In fact, my students even took it a step further (but more on that later).

Pumpkin STEM Goals

Preschoolers will be able to use this invitation to explore science, technology, engineering, and math concepts in age appropriate ways.

Here are some of the concepts it covers:

Counting
Number identification
One-to-one correspondence
Planning and building structures with unusual materials
Using technology in a simple project

Observing and interacting with your students during this pumpkin math project will be very eye-opening!

You’ll be able to observe what each child understands about each of the above topics. You might even be a little surprised by some of your students’ awesome observations.

Materials Needed for the Pumpkin Math and Engineering Activity

You don’t need very much to get this pumpkin STEM activity started (I may get commissions for purchases made through links in this post):

Old, stale pumpkin candy

Play dough

Magnetic numbers

Cell phone or camera

magnetic number 8 and eight candy pumpkins built with play dough

Pumpkin Math and Engineering Directions

Place the STEM challenge materials out on a tray, or just directly out on one of your tables.

Have the children come over individually or in small groups, depending on your preference and the children’s needs.

Explain to your students that you have a pumpkin challenge for them! Can they count and make different structures using pumpkin candies leftover from last Halloween?

My students could hardly wait to delve into the pumpkin STEM fun.

If your pumpkin candies aren’t as stale as ours were, you can try using flat toothpicks. This will add even more of a fine motor workout to the challenge.

Seeing as our pumpkins were super stale, we weren’t successful using toothpicks. So we moved onto using play dough as the “glue” to hold these STEM structures together.

To being, have each of your students choose a magnetic number, Talk with them about the number they chose.

Next, the children can count out the appropriate number of pumpkin candies, based upon their magnetic numbers.

Then let the children create their pumpkin structures!

I have to tell you, my students seriously enjoyed this pumpkin STEM activity! They planned and build, and then planned some more and built some more.

Their structures were random conglomerations and castles and pumpkin patches and “I don’t know what it is right now.”

Integrate the Technology into the Pumpkin STEM activity

Once the pumpkin structures are done, work with the children to take pictures of their STEM creations.

I allowed the children to use my cell phone to take pictures, and I also took a few photos.

You could also consider a school camera. Whatever you’re most comfortable with!

If your students are as interested in this pumpkin STEM challenge as mine were, I highly encourage you to take it a step further. We turned the photos into a pumpkin counting book, and it lived in our class reading center for months.

Have you tried a pumpkin STEM challenge like this one? If so, how did you set it up?

I found it so interesting to see who liked the different aspects of this activity. Some of the children were super into counting, others loooooved building, and a third group just wanted to take photos!
