Hi, I'm Elizabeth! I'm a retired educator with a love for playful, purposeful learning. I create literacy, math, and SEL resources for lower elementary levels because I want to support teachers who may feel overwhelmed by planning and want low-prep activities that are easy to use and fun to teach.
💜 In case you're wondering why my store is named PurpleLog - it was the name of my original educational company years ago, when I developed enrichment programs for schools across Singapore. The name itself comes from a fantasy story I created for my children when they were very young, all about a magical forest filled with purple logs. They loved it, and as they grew into wonderfully creative adults, the name became a meaningful reminder of those early stories and the joy of inspiring imagination. Today, I continue that spirit through the resources I create, hoping to spark the same sense of curiosity and creativity in children.
