Build The Tallest Shelf For The Elf Stem Challenge

"Oh no! The adorable Elf on the Shelf has … well … lost its shelf! Can you build him a new one? But wait! He has a special request. He would like his new shelf to be nice and tall. He needs to see everything you are doing, after all. Are you up for the challenge?My kids love this challenge because there love the elf on the shelf! They can’t wait for ours to come out right after Thanksgiving. But since we can’t touch the “official” elf, we are using a paper elf instead for this challenge."
