PERIOD 1: Time
PRESENTATION  TEACHER’S ACTIVITY  PUPIL’S ACTIVITY  
STEP 1 MENTAL MATHS  The teacher begins the lesson with some mental calculations How many 1. Minutes in ½ of an hour? 2 Minutes in ¼ of an hour? 3 Minutes in ¾ of an hour? 4 Minutes in 2/4 of an hour? 5 Minutes in an hour?
What are the following minutes in hour? 6 60 minutes 7 30 minute 8 15 minutes 9 120 minutes 10 45 minutes  Pupils respond and participate  
STEP 2 CONCEPT DEVELOPMENT  • In this activity the teacher revises analogue time. An analogue clock should be on hand to show to the class. Tells them it is called an analogue clock and compares it to a digital clock, which will be talked about in the next activity of this lesson. • Talks about the differences between the two kinds of clocks.
• Asks questions such as:  How many minutes are there in an hour? (60).  What do we mean when we say 4 o’clock? (That the time is exactly on the hour – not before or after.)  Show me 4 o’clock on this clock. (Get learners to come to the front of the class to demonstrate where the hands on the analogue clock should be to show the time.)  How many minutes in half an hour? (30)  When we read time, how do we say half an hour from the full hour or the o’clock? (half past)  On this clock show any time that includes half past and read the time to me. (Ask a learner to come to the front and demonstrate how to show e.g. half past three.)  Show me a time that is quarter past and quarter to. (Ask a learner to come to the front and demonstrate.)
CLASS ACTIVITY The teacher • Compiles a table like the one below on the board before the lesson. The digital clock column will be filled during the lesson. • Asks if any learners can read the time on cell phones, microwave ovens, etc. Discusses digital clocks by covering the following points:  Digital clocks can work in 24hour cycles – day and night. So we see any hour only once. On an analogue clock we have 12 hours for a.m. (morning) and 12 hours for p.m. (afternoon) but on the 24hour digital clock these are put together and we have 24 hours.  There are also 12hour digital clocks, where day and night times do not look different: 08:00 could be 8 o’clock in the morning or night. We will write times using a 12hour digital format.  If you had two watches, one analogue and one digital, and you need to show 8 o’clock in the morning, this is how it would look. (First show this on actual clocks, and then draw a clock face showing 8 o’clock for the analogue clock, and write 08:00 to show digital time next to it.)
• Uses analogue and digital clocks to show every hour, and ask learners to have a go at helping you to complete a table on the board from 01:00–12:00.
ACTIVITY II The teacher • Asks learners how we write these times in digital time:  half past three (3:30)  quarter past three (3:15)
• Asks: How do we write these times in analogue time: • 07:45 (quarter to 8) • 12:00? (twelve o’clock)
 Pupils pay attention and participate  
STEP 3 CLASSWORK  NOTE: These activities relate to a digital clock which is a 12 hour clock, so there is not a difference between morning and afternoon. 1 Write these times as digital times: a Half past seven. b Quarter past seven. c Quarter to 4. d Quarter past four. e Half past 5.
2 Write these times as analogue times: a 05:30 b 02:00 c 12:00 d 07:00
3 Show quarter past two on the clock: a Write the time below the clock. b How many minutes is it before 3 o’clock? c Where is the hour hand pointing? d Where is the minute hand pointing?  Pupils attempt their class work  
STEP 4 HOMEWORK  1 Show on the clock faces below: a 10 o’clock b 12 o’clock c 5 o’clock 2 Write the times shown on these clocks:  Pupils attempt their class work  
STEP 5 SUMMARY  The teacher summarizes by reminding the pupils how to tell the time using analogue and digital watches.
She marks their class works, makes corrections where necessary and commends them positively 

PERIOD 2: Measuring time
PRESENTATION  TEACHER’S ACTIVITY  PUPIL’S ACTIVITY 
STEP 1 MENTAL MATHS  The teacher begins the lesson with some mental calculations What is 5 less than a. 30 b. 45 c. 50 d. 60 e. 25 What is 5 more than f. 30 g. 45 h. 50 i. 60 j. 25
 Pupils respond and participate 
STEP 2 CONCEPT DEVELOPMENT  The teacher Uses an example of an analogue clock. Revises reading time from an analogue clock by counting on in 5s: • Asks: How many minutes are there in an hour? (60 minutes.) • Says: Let us count the minutes in one hour. (Start counting the minutes from 12 to 1 and point to the numbers on the clock face as you count – 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60.) • Asks: How many minutes are there in half an hour? (30 minutes.) • Says: Let us count the minutes in half an hour: (Start counting the minutes from 12 to 1 and point to the numbers on the clock face as you count – 5, 10, 15, 20, 25, 30.) • Asks: Can I count 30 minutes starting from another place on the clock? (Yes – discuss possibilities and try them out.) • Asks: How many minutes are there in a quarter of an hour? (15 minutes.) • Says: Let us count 15 minutes: (Start counting from 12 to 1 and point to the numbers on the clock face as you count – 5, 10, 15.) • Asks: Can I count 15 minutes starting from another place on the clock? (Yes – discuss possibilities and try them out.)
ACTIVITY II The teacher * Refers to the clocks below
* Revises the following with the learners.  How to read the time.  The drawings show analogue and digital clock faces.
* Discusses each of the times below with the class, making sure that learners are able to read the time correctly.

What is 15 minutes earlier f. 3.30 g.1.00 h. 4.45 i. 6.15 j. 7.00  Pupils respond and participate 
STEP 2 CONCEPT DEVELOPMENT  The teacher Method 1 demonstration – using a clock to calculate • Writes these questions on the board: At what time does school start each day? (8:00) At what time does school end each day? (1:30) • Asks: How many hours are we at school? • Uses an analogue clock as an aid. Ask them to place the hands of their clocks on 8 o’clock. They then count the: hours from 8 o’clock to 1 o’clock – 8:00, 9, 10, 11, 12, 1 → 5 hours and then the minutes from 1:00 to 1:30 → half an hour.
 The time spent at school is 5 hours + half an hour = 5 ½ hours.
CLASS ACTIVITY The teacher Method 2 demonstration – using a number line to calculate • Writes this question on the board:
Mom puts a cake into the oven at 3:45. It needs to bake for 1¼ hours. At what time must she take the cake out of the oven?
ACTIVITY III The teacher Method 3 demonstration – breaking down to calculate • Write this question on the board: Mercy takes 1½ hours to do her homework. Jenny takes half that amount of time. How long does Jenny take?
 1½ hours = 1 hour + ½ hour  Half of 1½ hours = half of 60 minutes + half of 30 minutes = half of 90 minutes = 45 minutes.  Jenny takes 45 minutes.  Pupils pay attention and participate
