Summer of STEAM

Wonder Wednesdays are part of our Summer of STEAM Series. I love activities that are super low-prep! That makes it even easier to get things set up quickly!

We are big on routines at our house, so we’ve sorted our activities into different “themed” days to keep the learning going all summer long!

Check out our Summer of STEAM activities for kids filled with Math Mondays, Tinker Tuesdays, Wonder Wednesdays, Techie Thursdays, and Foodie Fridays!

STEAM is the abbreviation for Science, Technology, Engineering, Art, and Math. Like STEM, STEAM is an integrated approach to learning that encourages learners to make connections between the concepts they are learning and how they apply them to real-world problems.

STEAM helps students ask questions, problem solve, think creatively, and produce innovative solutions.

Many schools have adopted STEAM learning activities into their curriculum, but it’s never too early to start building critical thinking skills.

We love low-prep STEAM activities at our house and have a blast doing activities designed for toddlers all the way to tweens!
