Teaching Moles through Beans

The concept of the mole has always been a challenging topic for myself and my students. The challenge comes in part when we try to imagine 6.02 x 1023 of anything.

Reflections from a Paperless Classroom

Like many schools, this year my school went 1:1. Each of our students was issued an 11 inch Chromebook with a webcam. Our upperclassmen have the the older Samsung models with a front-facing webcam and our underclassmen have the new Lenovo N22/23 models with a flippable webcam.

Now that I am halfway through the year (and still paperless!), I wanted to share what has been working well for me and where the snags have been.
