Guided Practice

- 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.
