765 765
A: Ricky got on the bus at 8:00 A.M. and
6 : 30 P.M.
got off the bus at 11: 00 A.M. 2 hours 4 : 30 P.M.
Plan the Process
Q: How will you solve the problem?
A: Count the number of intervals the hour
hand moved. c The plane takes off at 11:00
A.M. It lands at 3:00 P.M.

A: It moved 3 intervals.
765 11 : 00 A.M. 3 : 00 P.M.
So, 3 hours have passed.

Q: Is your answer reasonable ? 122
A: Explain how you solved the problem.
2. Build Understanding
In question 1c, students often make mistakes by turning the hour hand from 3 to 11 12 1 11 12 1
11. Have them understand that the clock hands must always turn clockwise (to 10 2 10 2
the right). 93 93

Students often don’t read A.M. or P.M. to read the times correctly. Explain that
after noon, the time changes from A.M. to P.M. and that after midnight, the time 765 765
changes from P.M. to A.M..
11 : 00 A.M. 3 : 00 P.M.
