About the Mathematics in Unit 3

We are beginning a new unit in mathematics called How Many Stickers? How Many Cents? In this second number unit, students focus on place value of 2- and 3-digit numbers. They are introduced to Sticker Station, a store that sells single stickers, strips of 10 stickers, and sheets of 100 stickers. They use this context, as well as money (pennies, dimes, dollar bill) and cubes organized in towers of 10, to think about how numbers are composed. Students also solve a variety of addition and subtraction story problems and play games that involve adding multiples of 5 and 10 up to 100 or $1.00. They read and write numbers to 500 and practice adding and subtracting 10 to 3-digit numbers.
