Our students in Fourth Grade are studying Native Americans, and I needed an activity to cement in what a wampum belt was. It’s a doing-type of group, so they made virtual wampum belts as I read to them. You can add one bead at a time or click the other radio button to “draw” in any of the purple or white shells. There is also an erase selection.
