I use this Smartboard activity to count to the 100th day of school. At my morning meeting I display this and ask students how many days we have been in school. Each day we add another penny to another finger. On the 5th day, we add a nickel to the middle of the hand, on the 10th day we add a dime between the two hands and on the 25th day of school we add a quarter to the end of the row. Students visually see the different combinations of coins for each day they have been in school. As a challenge for students, they can add all of the money up for a grand total. I save it each day so the money stays on the hands and it's continuous.
