Build a map using a key, a compass rose, and symbols, then read a partner's map to find a marked spot.
You have learned a lot about maps: a key that explains symbols, a compass rose for directions, and how to show land and water. This week you use ALL of it to make a treasure map.
A good treasure map needs a key, a compass rose, at least two symbols, and a clearly marked spot -- an X or a star -- for the treasure. Then you trade maps with someone and try to find each other's spot.
Mastery looks like: They build a map with a working key, compass rose, and symbols, and can read a partner's map to find the marked spot.
Common stumbles: Leaving out the key or compass rose, which makes the map impossible for someone else to actually follow.
