We made these as a parent gift for Valentines Day and they really enjoyed it! We folded one of the printables and glued it on the back to make it a card. I do have to say that it was a tiny bit difficult because of the many different parts and the amount of cutting they had to do (even for Grade 3's!) so that's something to keep in mind if you have a group with low fine-motor skills!
What a cute activity! My students did one of the writing pieces first. Then, they constructed the bubble gum machine and we attached both together and hung them in the hallway. We have received so many compliments.
