I created this challenge for the early finishers in my classroom. I put together 12 small collections of coins in Easter eggs, then marked each egg with the letters A-L. Students were to count the coins in each egg that was placed around the room, then try to add up all of the collections to see how much money there was total. Note to teacher--go through and make yourself an answer key first! Also, remind kids to not to drop any of the coins or let them roll away, as that will change the whole answer in the challenge! You could also just put together 12 small collections of coins in plastic bags or envelopes!
