About the store

Hey there! I’ve subbed in every grade (yes, even kindergarten!) and spent two years in 4th and 5th before diving into special education. Now I’m in year 9 as a high school intervention specialist, supporting math classes from Algebra 1 to Data Science in my years in high school. I like to say we SPED folks know a little about everything—so my resources are made to be flexible, fun, and super classroom-friendly. Thanks for checking out my store!

Teaching style

I’m all about structure with a side of fun. My teaching style mixes clear expectations, creative twists, and just enough humor to keep things real. Whether I’m supporting math students or creating resources, my goal is simple: make learning feel doable, engaging, and a little fun—even when it’s Geometry before 9 a.m. 😉
