Lesson 2  Telling Time: Telling
Time: Half Hours
Vocabulary
digital clock
minutes
onehalf
halfpast
Objectives
To teach telling time to the half hour
To introduce telling time on a digital clock.
Background
Discuss the differences between the two clocks:
digital and a clock with hands.
Discuss the differences between the hour hand and minute hand.
Discuss the fraction 1/2.
Show 4 o'clock on a demonstration clock. Move
the minute hand halfway around the clock to 6 while children count
by fives.
Ask:
How many minutes have passed?
Where does the minute hand point?
Where does the hour hand point?
What time is it?
Write fourthirty , 4:30 and half past 4 on the chalkboard.
Continue moving the 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) Where is the minute hand at half
past the hour?
Activities:
1. Play "Time Concentration." Prepare
cards showing several times on the hour and half hour. Also prepare
matching cards with clock faces illustrating these times. Turn
all cards face down individually. Students may play one to one
or form partners to play the game. One student turns over two
cards, trying to match a clock face with the corresponding time
card. If the cards match, the student removes the cards and keeps
them. If the cards do not match, the student replaces the cards
face down, and the next player takes a turn. The game continues
until all the cards are matched. The player with the most matches
wins.
2. Reinforce skills at a learning center for telling time. Prepare
cards showing clock faces on the half hour. The students will
match the clock faces to cards which record the time in standard
notation form or with the words 'half past' the hour.
3. Have students make their own TV
guides. For each program the student must record the day,
channel and time, and draw a clock face indicating when the show
begins.
