half-past

Objectives

To teach telling time to the half hour

To introduce telling time on a digital clock.

Background

I will discuss the differences between the two clocks: digital and a clock with hands.

Next I will explain the  differences between the hour hand and minute hand.

Discuss the fraction 1/2.

Then I will show  where the 4 o'clock on a demonstration clock. I will move the minute hand halfway around the clock to 6 while children count by fives.

Materials:

Digital Clock

Auto Clock

Ask:

How many minutes have passed?

Where does the minute hand point?

Where does the hour hand point?

What time is it?

Then I will write four-thirty , 4:30 and half past 4 on the chalkboard.  I will go on until minute hand around the clock to 12 while children count by fives.

Ask:

How much time has passed?

What time is it now?  

Discuss the two ways to read time at the half hour. (4:30 and half past 4)

TV GUIDE ACTIVITY

This is a great idea. I will have students make a TV guide!. For each program the student must record the day, channel and time, and draw a clock face indicating when the show begins.  For this I would have them only do it for the times on half the hour to reinforce learning half past.
