Wow! This classroom is filled with organization and classroom decor ideas. She includes tons of photos and links in her blog post. It's a MUST SEE for all kindergarten, first grade, second grade, third grade, and fourth grade teachers!
Hall Pass - Print on card stock and put into ID badge holders on coil key chains (both from Walmart). Blank pass at end can be written on with a whiteboard marker and then erased (for students who have to go somewhere else in the building). These are waterproof (seal the top opening with packing tape or buy self-seal ID badge holders) and kids wear them high up on their arms so they don't get wet/dirty in the bathroom.
