Four Quadrant Coordinate Spelling
Letters of the alphabet are scattered around the coordinate plane. I use this for students to become familiar with the coordinate plane. I pair the students up and have then encode/decode messages from each other. I have also paired with the ELA teacher to give a spelling test. The kids loved it, but it was daunting to grade. Next time, I would offer a couple of bonus words with the coordinate spelling.
