I originally bought the sample sets at Michaels for my 5 year old sons lunch. I thought he’d read em(he loves to read and reads EVERYTHING) and then throw them away but I then I kept finding them in his backpack, with his homework, and in his pockets. HE’S KEEPING THEM! I was so excited and he also gets excited whenever I ask him about them. I just purchased sets 5-8 and can’t wait to get them. Thanks so much for creating these to help me remind my son how important he is!
