Teacher Notes (not visible to students)

The website for the geoboards is a free website from mathlearningcenter.com. It is also a free app for the iPads. Although students could label and draw on this app, I like the options Seesaw provides more for labels and drawing. https://apps.mathlearningcenter.org/geoboard/
