Print the page so that you have enough for each student in your class (if you have 24 students, print the page 12 times). Cut each page in half. Put students in pairs giving each person in the pair half of the sheet. In this drill, students take turns asking each other the time. Each student knows what his/her partner should say.
When the students get to the bottom of the sheet, they should switch papers and do it again. In my classroom, I instruct students to repeat the drill until I tell them to stop.
