Factors, Multiples, and Regular Polygons

We will get together in Zoom three times a week for group activities and discussions, and there will be work for learners to do on their own time between sessions. During group activities, learners will work hands-on with GeoGebra and interact with the teacher and each other through slides that are designed to be written on and organize our thinking, not just looked at, in the Explain Everything whiteboard platform. (Learners can either annotate from within Zoom, which will be reset as we move between slides but preserved in the session recording, or request the Explain Everything link, which will let them write directly on the board that will be exported into downloadable class notes. Learners' contributions will be checked for appropriateness, safety, and accuracy before being exported.)

Consistent regular attendance is expected. Learners will not be removed from class for missing group activity sessions, but will be responsible for catching up by watching the session video and doing all work. I will be available to help if they find anything tricky.
This class is based on a unit from Illustrative Mathematics for 4th Grade, so learners should already be familiar with early elementary school arithmetic skills and strategies, like whole number addition and subtraction using a number line. Needing to refresh their memory, typical of returning to school after the summer slide, is OK!
