  • Display the following equation and tell students the quotient is missing a decimal point: 29.8 ÷ 73 = 8. Ask students to brainstorm in parters where they should put the decimal point in the quotient.
  • Gather information on their background knowledge by listening for their understanding of the key terms ("quotient," "decimal point") and their ability to accurately place the decimal.
  • Ask volunteers to share their answers and see if they can explain their reasoning. Some answers may focus on the fact that 298 ÷ 73 = 8, not 29.8 ÷ 73 = 8, and that they need to move the decimal to the left in the quotient to create the correct equivalency (29.8 ÷ 73 = 0.8).
  • Tell students that by the end of the lesson, they should know how to explain their decimal placement by relating the decimal division problem to an equation of solely whole numbers.
