Teaching first graders all about money is a common core skill they have to master. It's really a life skill. I tell my firsties that what they learn about money in first grade they will know until the day they die. Ha! I seem so powerful. I'm not really.
One of my favorite warm up activities for math is to pass out handfuls of coins for my kiddos to sort and count. The kids hated it at first but quickly learn to love it. It was hard to distinguish between all of the different coins. I give them sticky notes to write down how much is in each pile they created. It has been amazing how they are getting very good a counting by 5's, 10's and even 25's. They count all of their coins together by counting on. They love understanding the whole dollar thing. Here are a few pictures of my kids in action with the coins.
Start each day in a happy way:)
