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
We do (1)Ross arrives at his bus stop for school at 8:35 each morning. He completes his morning routine before he leaves for school. It takes John 5 minutes to walk to his bus stop. He spends 15 minutes eating breakfast. What time did Ross complete his activities?
What do we label on the 1st clock? Next, we must count ahead how many minutes?Where should the 1st set of elapsed time be labeled?
Lastly, count ahead how many minutes?Where should the 2nd set of elapsed time be labeled?What clock shows the elapsed, end time for Ross?
We do (2)Carlos arrives home from school at 4:15 PM. He reads for 20 minutes. Then, Carlos works on his math homework for 25 minutes. He practices his spelling for 5 minutes. Then he practices his math facts for 5 minutes. What time does he complete his homework?
What do we label on the 1st clock? Secondly, we must count ahead how many minutes?Where should the 1st set of elapsed time be labeled?Thirdly, we must count ahead how many minutes?
Where should the 2nd set of elapsed time be labeled?Fourthly, we must count ahead how many minutes?Where should the 3rd set of elapsed time be labeled?Fifthly, we must count ahead how many minutes?Where should the 4th set of elapsed time be labeled?
We do (3)Solve for the problem below by counting the elapsed time backwards.
Monica takes piano lessons at her neighbor’s house on Saturday. She arrives home after her lesson ends at 11:00 AM. It takes her 5 minutes to walk home after her lesson. She does a piano warm up for 10 minutes. What time did Monica begin her activities?
Label the 1st clock to show the time 11:00.Next, count backwards 5 minutes, then label this time on the 2nd clock.Lastly, count backwards 10 minutes, then label this time on the 3rd clock.The 3rd clock shows the elapsed, end time. What is the elapsed, end time?
