EngageNY 60 min(s)

In this lesson, students begin to model subtraction of decimals. They first model subtraction of decimals using place value chips and charts. For example, students model 7 ones 5 thousandths - 2 ones 3 thousandths. Then they make connections between the concrete representation and the vertical written method. Finally, students model subtraction of decimals written in a mixed format, 9.2 - 6 ones 4 tenths.
