In this lesson, students begin to model multiplication of decimals by single-digit whole numbers. They first multiply numbers written to the tenths place, using a place value chart and representations of place value disks. Students compare the model to the standard algorithm. For example, students solve 3 x 0.3=0.9. Then, students multiply numbers written to the hundredths and thousandths. Students compare the place value chart to the area model. Finally, students use the area model to represent the distributive property.
