Grade 4 math worksheet focusing on telling time, with exercises to calculate time intervals between clock pairs and draw clocks for specified times.

Problem Analysis:

The worksheet is divided into two main sections:
1. Telling the Time Interval Between Pairs of Clocks: Here, we need to determine the time difference between two given clock times.
2. Drawing Clocks to Show Specific Times: Here, we need to draw clock faces to represent the given times.

Let's solve each section step by step.

Section 1: Telling the Time Interval Between These Pairs of Clocks

#### Row 1:
- Clock 1: The hour hand is on 6, and the minute hand is on 12. This represents 6:00.
- Clock 2: The hour hand is between 3 and 4, closer to 3, and the minute hand is on 8. This represents 3:40.
- Time Interval Calculation:
- From 6:00 to 3:40 involves crossing midnight.
- Calculate the interval from 6:00 to 12:00: \(6\) hours.
- Add the interval from 12:00 to 3:40: \(3\) hours and \(40\) minutes.
- Total interval: \(6 + 3\) hours and \(40\) minutes = 9 hours and 40 minutes.

#### Row 2:
- Clock 1: The hour hand is between 9 and 10, closer to 9, and the minute hand is on 6. This represents 9:30.
- Clock 2: The hour hand is between 10 and 11, closer to 10, and the minute hand is on 7. This represents 10:35.
- Time Interval Calculation:
- From 9:30 to 10:35 involves a straightforward calculation.
- Calculate the interval: \(1\) hour and \(5\) minutes.
- Total interval: 1 hour and 5 minutes.

#### Row 3:
- Clock 1: The hour hand is between 10 and 11, closer to 10, and the minute hand is on 10. This represents 10:50.
- Clock 2: The hour hand is between 1 and 2, closer to 1, and the minute hand is on 1. This represents 1:05.
- Time Interval Calculation:
- From 10:50 to 1:05 involves crossing midnight.
- Calculate the interval from 10:50 to 12:00: \(1\) hour and \(10\) minutes.
- Add the interval from 12:00 to 1:05: \(1\) hour and \(5\) minutes.
- Total interval: \(1 + 1\) hours and \(10 + 5\) minutes = 2 hours and 15 minutes.

#### Row 4:
- Clock 1: The hour hand is between 7 and 8, closer to 7, and the minute hand is on 4. This represents 7:20.
- Clock 2: The hour hand is between 8 and 9, closer to 8, and the minute hand is on 7. This represents 8:35.
- Time Interval Calculation:
- From 7:20 to 8:35 involves a straightforward calculation.
- Calculate the interval: \(1\) hour and \(15\) minutes.
- Total interval: 1 hour and 15 minutes.

#### Row 5:
- Clock 1: The hour hand is between 1 and 2, closer to 1, and the minute hand is on 10. This represents 1:50.
- Clock 2: The hour hand is between 2 and 3, closer to 2, and the minute hand is on 12. This represents 2:00.
- Time Interval Calculation:
- From 1:50 to 2:00 involves a straightforward calculation.
- Calculate the interval: \(10\) minutes.
- Total interval: 10 minutes.

Section 2: Draw the Clocks and Show the Following Times

#### Part (a): 8:15
- Hour Hand: Between 8 and 9, closer to 8.
- Minute Hand: On 3 (which represents 15 minutes).

#### Part (b): 22:30 (or 10:30 PM)
- Hour Hand: Between 10 and 11, closer to 10.
- Minute Hand: On 6 (which represents 30 minutes).

#### Part (c): 15:15 (or 3:15 PM)
- Hour Hand: Between 3 and 4, closer to 3.
- Minute Hand: On 3 (which represents 15 minutes).

Final Answers:

#### Section 1: Time Intervals
1. 9 hours and 40 minutes
2. 1 hour and 5 minutes
3. 2 hours and 15 minutes
4. 1 hour and 15 minutes
5. 10 minutes

#### Section 2: Draw the Clocks
- (a) 8:15: Hour hand between 8 and 9, closer to 8; Minute hand on 3.
- (b) 22:30: Hour hand between 10 and 11, closer to 10; Minute hand on 6.
- (c) 15:15: Hour hand between 3 and 4, closer to 3; Minute hand on 3.
