Righteous Rounding: Rounding Decimals

Explicit instruction/Teacher modeling

• Display the How to Round Decimals attachment for the class to see.
• Hand out a copy of How to Round Decimals to each student.
• Read aloud the first page of the attachment to the class as they follow along.
• Model how to round the numbers and decimals on the second page of the attachment as the students follow along and write as you model.

Guided practice/Interactive modeling

• Refer the students' attention to the 10 numbers you have previously written on the board.
• Ask for students to volunteer to come to the board and round each number to the place value you give them. Give a variety of place values to round to.
• In an easily accessible area in the room, place several copies of each of the Barber Shop Round Off #1, #3 and #5 worksheets.
• Arrange the students into pairs and have one of the pair pick up 2 different Barber Shop Round Off worksheets for the pair to work on together.
• Remind the pairs to write both of their names on each worksheet so they both get credit.

Independent working time

• For independent work time, instruct the students to pick up the Barber Shop Round Off worksheet they did not complete as a pair to work on independently.

• Enrichment: Have advanced students complete the Barber Shop Round Off #2 and #4 during independent work time.
• Support: Pair students who need support with a student who understands the concept during the guided practice.

• Use the graded independent work time worksheet as an informal assessment.

• As a fun review, have the students play The Rounding Race game. You can have pairs of students help create the game or have the game prepared ahead of time.
