Remind your students that there is more than one way to begin solving a division problem. Tell your students to "just begin" and then to adjust as needed. Give your students these problems: 531 ÷ 16; 364 ÷ 22; 1,506 ÷ 24; 3,186 ÷ 45. Ask them to first estimate the quotientsand then to find the actual quotients.
