Materials. All students will need their own compass. They will need these everyday for the remainder of the unit. Not having a compass will make them unable to participate or complete assignments.
If your student needs a compass, as of 2:29pm today, Office Depot on Cedar Hills Blvd has 22 in stock. This is the model I recommend.
Students need to take care to not break the metal tip off and not lose the plastic screw. If a metal tip breaks I can glue it back in fairly successfully. If they lose it, it can be replaced with the head of a nail.
