Another idea is to send candy grams for valentines day, however you must
include a tootsie pop valentine for all those who do not get any and
limit the number sent to 3 to keep it fair and even. Which means having
class lists and marking the number sold for each student.
This can be done before and after school and lunch.
Lastly, you could open a mini school store selling pencils, pens,
notebooks and healthy snacks, also fun erasers etc.
