I do (1)Craig began reading a book at 3:15. He read for 45 minutes. What time was it when Craig finished reading?

Label the 1st clock to show the time 3:15. Next, on the 1st clock, count ahead 45 minutes to determine Craig’s reading end time, then label his end time on the 2nd clock. The 2nd clock shows the elapsed, end time for how long Craig read. CLOCK 1 CLOCK 2

I do (2)Elena is a student in Mrs. Gaines’ 3rd grade class. She begins recess at 1:10 PM. She talks to her friends for the first 5 minutes of recess. After she talks to her friends, she plays basketball for 10 minutes. What time did Elena complete her activities?

Label the 1st clock to show the time 1:10. Next, count ahead 5 minutes on the 1st clock to determine when Elena stops talking to her friends, then label this time on the 2nd clock.

Lastly, count ahead 10 minutes on the 2nd clock to determine when Elena stops playing basketball, then label this time on the 3rd clock. The 3rd clock shows the elapsed, end time
