Alert, alert, alert! You may want to go and update pic collage on your student iOS devices. If you update now, you get some free holiday backgrounds as well as some sticker packs! This would be espcially fun with Christmas break rapidly approaching.
Some sticker packs require that you create an account. If you really want your students to have those stickers, we can create a teacher account, log each device into it and have the students download the stickers. Once they are downloaded, we can then have the students log out of the account so that you do not have to worry about the students posting collages under your name to the entire world. The stickers are still usable even once logged out of the account.
