Alisa has a bunch of coins. She has pennies. She has nickels. She has dimes. She has quarters. They lie in one big pile. Alisa wants to organize her coins. So she goes into her cupboard and finds four jars. Each jar has a different shape and size. Alisa puts the pennies into one jar. She puts the nickels into another jar. She puts the dimes into another jar. She puts the quarters into another jar. Then she puts all four jars on the table and steps back. Looking at them, Alisa scratches her head.
