Professional Learning Communities, or PLCs, provide a collegial network for educators to reflect on and improve their practice. We look at an evaluation of a pre-packaged PLC program that did not improve PLCs in schools, and wonder how we can support educators at the building level instead. Later, we look at how very early math is learned by children. They experience the snowball effect, meaning it is far more important that learners have experiences with math regardless of the specific types of math they may experience. Math is good, m’kay.
