About the store
Hello! I'm Chrissie...veteran teacher of 24 years. Passion and creativity float my boat. I design time-saving learning materials for upper elementary students that are unique and fun. From lapbooks to scavenger hunts and lockbox challenges, you'll find plenty of tools to keep your students on the edge of their seats. I am a Pennsylvania public school educator. After student teaching in kindergarten, I began my career as a second grade teacher. Shortly thereafter, I became a first to second grade looping teacher. I then moved to third grade for 14 years before becoming a K-5 gifted support teacher. I have enjoyed every age level along the way! Each grade level brings so many different rewards and challenges to make life interesting.
