Lesson 2 – Half Past

Objectives:

At the end of the lesson, students should be able to identify times that are half-past any given hour.

Most clock faces have numbers from 1 to 12. Also there are usually small or tiny strokes between the numbers. Each stroke is equal to one minute.

Therefore, there are five strokes = 5 minutes between any 2 numbers on the clock face.

For instance, from 12-1, there are 5 minutes. From 6-7=5 minutes.

To find half-past of any particular hour, there is the need to count in fives from 12 until we arrive at 30.

Example:

To show half past 10 on the clock,

From the example above, the time on the clock’s face is half past 10 or 10 : 30.

Using the counting method, from

12 – 1 = 5 minutes

1 – 2 = 5 minutes

2 – 3 = 5 minutes

3 – 4 = 5 minutes

4 – 5 = 5 minutes

5 – 6 = 5 minutes.

5 + 5 + 5 + 5 + 5 + 5 = 30 minutes.

Note that, it is half past a number only if the short hand (hour hand) is pointing half-way between the 1^st and 2^nd number while the long hand (minute hand) is pointing to 6.

Example 2

What time is shown on the clock face?

The time is Half-past 2 or 2 : 30. Note that, the hour hand is between 2 and 3.
