A few years ago I noticed our school principal using address labels in a creative way. Rather than putting an address on them, she put an encouraging message.
It took me years to do anything with this great idea.
We'll see how these work this year - I have one Happy Birthday set, two sets with the Six Traits of Writing (I can use them on student work and highlight or circle the trait(s) they are doing well), and one with an "I'm proud of you" message. I'm excited about the potential connection with students that can come from these little stickers!
