This bookmark set is a wonderful way to personalize your end of the year gifts to your students! I punched a hole in the keys where you would normally add your key to a key-chain and did the same with the bookmarks (its up to you whether or not you want to punch 3 holes in the bookmark to make it look more like folder paper). I then attached the keys to the bookmarks with yarn and wrote a personalized message to each of my students! This product can work with any grade, though you may want to use it mainly for those grades who already have a good grasp on reading. The kids will love having a personal reminder of their time with you and will know that you believe in them as they continue their learning careers!
