Teacher Peach Happy Birthday Kit Greet birthday students with a colorful certificate. This kit comes with a pack of 25. Just add the student's name and the date with a Sharpie marker. Students can bring home this memorable certificate that features a poster on the reverse side to hang on the fridge. Each poster measures 8.5 inches in height x 11 inches in width. There's even a spot for some reflection, an important CCSS strategy. Students just flip over the certificate to answer, "Why is your birthday a GREAT DAY?" . Each kit also comes with two sheets of 15 1.5-inch stickers. Top it all off with the coordinating postcard from the pack of 25 to jot a short personal note to sum up the day. Each postcard measures 6 inches in width x 4 inches in height. Tuck the postcard into the student's take home folder or drop it into the mail a few days ahead of time. These kits are a great way to create a special birthday for each and every student.
