Math Live – Time: Assessment Task
Grade: 4 Strand: Shape and Space (Measurement) Outcome: 1
SPECIFIC LEARNER OUTCOMES – Space and Shape (Measurement)
SS 1 Read and record time, using digital and analog clocks, including 24-hour clocks.
PROCESSES Communication (C), Connections (CN), Mental Mathematics and Estimation (ME), Problem Solving (PS), Reasoning (R), Technology (T), Visualization (V)
C, CN,V EVIDENCE the student has achieved the outcomes
Each student will
• Explain the meaning of time expressed in 24-hour language (fifteen thirty-three) using words and drawing.
• Explain the similarities and differences of telling time using a 12-hour and 24-hour system.
• Show time on both an analog and digital clock using 12-hour time notation. • Show time on a 24-hour analog clock and write the 24-hour time digitally. • Relate daily activities to time using both a 12-hour and a 24-hour system.
TEACHER NOTE
• In this assessment task, students will be asked to demonstrate their understanding of time in both the 12-hour and 24-hour systems.
• They explain the meaning of a time expressed in 24-hour language (fifteen thirty-three) to tell what time an event at an Air Show begins.
• Students then explain the relationship between the 12-hour and 24-hour time systems.
• They select an activity they do in the morning and show the time this activity occurs on both an analog and a digital clock using the 12-hour system. They then choose an evening activity and show the time this activity occurs on a 24-hour analog clock. The student will also write the time digitally.
• Materials required: students may be provided with clock manipulatives. • The 12-hour time system has two reference points. The amount of time
elapsed from midnight is expressed using the notation a.m. The amount of time elapsed from noon is expressed using the notation p.m.
The 24-hour time system has only one reference point. The amount of time elapsed from midnight.
• Early finishers can explore time zones and calculate the current time in various time zones across Canada.
• There are no exemplars available for question 4 and 5.

Math Live - Time: Student Assessment Task
You are at an air show with your friend. You are both anxious to see the Apache helicopter take off. You overhear the pilot say, “The Apache will take off at fifteen thirty-three.” Your friend asks you what “fifteen thirty-three” means.
1. Use words and drawings to explain to your friend what fifteen thirty-three means.
2. What is important to remember about how you tell time on a 12-hour clock and on a 24-hour clock? How are they the same? How are they different?
3. Think of one activity you like to do in the morning and one activity you
like to do in the evening. Write the name of each activity on the line provided. Show what time each activity occurs both digitally and on the analog clock below.

4. An air flight arrives at 21:05 and departs at 22:18. Use numbers and drawings to write each time another way.
5. A sign used the 24-hour clock to show No Parking from 3:30 p.m. to 6:00 p.m. What times must have been written on the No Parking sign?
