I’ll never forget my first year trying STEM in the classroom. I was excited, my students were curious, and…I had no idea what I actually needed. I had a few random supplies tucked in bins, a handful of science books on the shelf, and big dreams of engaging, hands-on activities.

But starting off, I was digging through my art bins for tape and silently hoping we had enough pipe cleaners to go around.

It wasn’t a disaster—but it was a learning moment.

Since then, I’ve fine-tuned a simple system to make sure I have everything I need to launch a successful STEM week, all without the last-minute scramble. Whether you’re a seasoned STEM teacher or just starting to dip your toes into hands-on learning, having a go-to toolkit can make all the difference.

In this post, I’m sharing my favorite materials, books, and a free printable checklist to help you feel prepped and confident for your first week of STEM.

Pete the Cat: Construction Destruction

Pete gets out to the playground and it’s a mess. He works together with his friends to rebuild in a whole new way. Great for perserverance and teamwork.

What Do You Do With a Problem?

This is a great story for growth mindset and to encourage students to face problems head on. Great for those nervous students who are afraid of failing in STEM activities.

Uma Wimple Charts Her House

A cute story about Uma trying to create her house through various different charts. Included are pie charts, graphs, venn diagrams, etc.! Love the visual representation of each chart.

Iggy Peck Architect

A silly start about a boy who builds with whatever materials he can find (including used diapers. This one is a great tale for talking about engineering design. Oh and it rhymes!

If I Built a House

This story leans into the engineering design process. The creativity and out of the box thinking can inspire the youngest of minds!
