My students love these brag tags! Print them on colored card stock, laminate, cut, and use a single hole punch to attach to a necklace.
I use incentive charts and keep them in a booklet with students' names. For each student, a good day is worth one sticker. 20 stickers of a particular color is worth a brag tag. An exceptional day can be worth two stickers, which is why I had to add more tags.
You can buy star stickers with the tag colors online or at teacher stores.
