This is how I prepare for my kiddos' birthdays.
I bought a variety of birthday packs from Walmart,
on clearance for 50 cents per pack of 12.
Each pack comes with 4 bags, 4 party hats, and 4 blowers
(about 12 cents per student).
I added a birthday sticker, a pencil, and a little notebook.
About a quarter per student.
(I think that's a pretty good deal!)
This is the larger, clear container I am using to store the birthday bags. I made more than the number of students; this allows my kiddos to choose the bag they want on their birthday.
Just add a label to the outside of your container and your birthday treats are set! (Not shown)
