Gingerbread House STEAM Activity: Math Connections for Grades 1–8

If you are like me, you are wracking your brain for a holiday-themed STEAM activity for your class. There are several possibilities for non-religious themes. I have looked through many of the ideas: cutting out snowflakes, decorating trees, making paper strip stars, etc., but the one I like the best is constructing a gingerbread house out of graham crackers. Gingerbread houses are part of many holiday traditions and associated with winter, so it is a reasonably safe choice for most classes.

Polya’s Problem-Solving Steps: Finding Unknowns Elementary and Middle School

It is unfortunate that in the United States mathematics has a reputation for being dry and uninteresting. I hear this more from adults than I do from children—in fact, I find that children are naturally curious about how math works and how it relates to the world around them. It is from adults that they get the idea that math is dry, boring, and unrelated to their lives. Despite what children may or may not hear about math, I focus on making instruction exciting and showing my students that math applicable to their lives.

How to Use Teddy Bear Counters in the Elementary Math Classroom

Teddy bear counters have become near and dear to many early elementary math educators. Having come from mostly a middle- and high-school teaching background, I first encountered the use of teddy bear counters in an early childhood development class. At first I thought it was simplistic, but the more I have learned about elementary mathematics, the more I see their benefit to math teachers and students alike.

Connecting Ten Frame Activities to Number Bonds and Number Sentences, K–2

When I visit classrooms, I often see students engaged in wonderful fun activities, but I can’t help noticing that these activities don’t always connect to the math ideas that the teacher is hoping to explain. I have worked hard in my own teaching to help students make the connection between fun and understanding, and I hope this post gives you some insight into how I do this.
