Adorable positive posters. FREEBIE! Could be a starting point for students creating their own.
rainbow writing (did something similar to this with the alphabet when one of my nanny charges were in kindergarten --- except they picked the color traced the letter 3 times, said the letter name and sound(s), repeated with at least 4 other colors), so I love this for learning spelling words. Could make writing them so much more fun and exciting.
