Habari Mwanafunzi! Welcome to the Safari ya Wakati (A Journey Through Time)!
Have you ever wondered how we know when it's time to wake up for school, when to have our break time, or when your favourite TV show is on? We use time! Time helps us plan our day, just like a map helps a driver on a safari. Today, we are going to become expert time-tellers! Are you ready? Let's go!
What is a Clock? The Face of Time
A clock has a face, just like you! But instead of a nose and mouth, it has numbers and two very important hands.
- The Short Hand is the Hour Hand. It moves slowly and tells us the hour.
- The Long Hand is the Minute Hand. It moves faster and tells us the minutes.
Let's look at a simple clock:
12
11 1
10 2
9 3
8 4
7 5
6
Image Suggestion: A vibrant, colourful cartoon clock with a big friendly smile. The clock hands are shaped like fun arrows. The background is a cheerful Kenyan landscape with an acacia tree and a giraffe peeking from the side.
Telling Time: "Saa Kamili" (O'clock)
This is the easiest time to read! When the long minute hand points straight up to the number 12, we say it is "o'clock" or "saa kamili". We then look at the short hour hand to see which hour it is.
A Day with Akinyi:
At 7 o'clock in the morning, the school bell rings. Akinyi runs to the assembly ground. The long hand is on 12, and the short hand is on 7.
At 1 o'clock in the afternoon, it's lunchtime! Akinyi eats her githeri. The long hand is on 12, and the short hand is on 1.
At 4 o'clock in the evening, school is over! Akinyi goes home to play. The long hand is on 12, and the short hand is on 4.
Here is what 3 o'clock looks like:
12
11 1
10 2
9 ------O---> 3 (Short hour hand points to 3)
8 4
7 5

(Long minute hand points to 12)
Telling Time: "Na Nusu" (Half Past)
What happens when the minute hand travels halfway around the clock? Think of sharing a warm chapati. When you cut it in half, you get two equal parts. When the minute hand goes halfway, it points down to the number 6. We call this "half past".
So, if the short hour hand is halfway between 8 and 9, and the long minute hand is on 6, it is half past 8 (which is the same as 8:30).
Image Suggestion: A lively illustration of a Kenyan primary school playground during break time. Children are running, skipping, and sharing snacks like mandazi. A large clock on the school wall clearly shows the time as half past 10 (10:30).
Units of Time: From Seconds to Hours
Time is measured in different units, some small and some big. Let's learn the most common ones!
- Seconds: These are very short! A clap or a snap of your fingers takes about one second.
- Minutes: These are made of seconds.
- Hours: These are made of minutes.
Here is how they are connected. It's very important to remember this!
60 seconds = 1 minute
60 minutes = 1 hour
Let's Do Some Time Maths!
We can add time! Let's try a real-life problem.
Scenario: Cooking Chapati
Mama Wanjiku starts cooking chapati for dinner at 6:00. The chapati takes 30 minutes to cook. What time will they be ready to eat?
Let's solve it step-by-step:
Step 1: Write down the starting time.
Start Time = 6:00
Step 2: Add the minutes it takes to cook.
Time to add = 30 minutes
Step 3: Add the minutes to the minute part of the time.
00 minutes + 30 minutes = 30 minutes
Step 4: Combine the hour and the new minutes.
The final time is 6:30.
Answer: The chapati will be ready at 6:30!
Morning or Evening? A.M. and P.M.
How do we know if it's 7 o'clock in the morning for school or 7 o'clock in the evening for dinner? We use A.M. and P.M. to help us!
- A.M. (Asubuhi): This is for the time from midnight all the way to noon. It's morning time!
- P.M. (Jioni na Usiku): This is for the time from noon all the way to midnight. It's afternoon and evening time!
What do you do during A.M. and P.M.?
- 8:00 A.M. - You are in class, maybe learning Mathematics!
- 10:30 A.M. - It's break time!
- 1:00 P.M. - You are eating lunch.
- 4:30 P.M. - You are playing football with your friends.
- 8:00 P.M. - You are listening to a story before you sleep.
Image Suggestion: A split image. The left side shows a bright sunny morning in a Kenyan village, with a child in school uniform waving goodbye to their parents. A sun with "A.M." is in the sky. The right side shows the same village in the evening, with a warm orange sunset. The same child is now sitting with their family around a small fire, listening to a grandparent tell a story. A moon with "P.M." is in the sky.
Great Work, Time Explorer!
Wow! You have learned so much about time today. You can tell the time, understand minutes and hours, and even know the difference between A.M. and P.M. Time is all around us, in everything we do. Keep practicing looking at the clock, and soon you will be a master of time!
Habari Mwanafunzi! Welcome to the World of Time!
Have you ever wondered why you wake up when the sun is rising, go to school, and then come home to play when the sun starts to set? Or why your favourite cartoon is on TV at a specific moment? That is all because of TIME! Today, we are going on an exciting journey to become Time Masters. We will learn how to read that friendly round thing on the wall called a clock. Are you ready? Let's go!
Image Suggestion: An illustration of a friendly, smiling cartoon sun and moon over a Kenyan village landscape. A group of happy, diverse Kenyan children are playing below, looking up at a large, colourful clock in the sky.
Meet Our Friend, the Clock! (Kusooma Saa)
A clock has a face, just like you! But instead of eyes and a nose, it has numbers and hands. Let's look at it closely.
---
/ \
/ \
| 12 / 1 |
| 11 | 2 |
| 10--O----3 | <--- The Short, Strong Hand (Hour Hand)
| 9 4 |
| 8 5 |
| \ 6 | <--- The Long, Fast Hand (Minute Hand)
\ /
\ --- /
- The Numbers: The clock has numbers from 1 to 12.
- The Hands: It has two very important hands.
- The short, strong hand is the HOUR hand. It moves slowly, like a tortoise. It tells us the hour.
- The long, fast hand is the MINUTE hand. It moves faster, like a hare. It tells us the minutes.
Telling Time: "O'clock" (Saa Kamili)
When the long minute hand points straight up to the number 12, it is a new hour! We say it is "o'clock". To know which hour it is, we just look at where the short hour hand is pointing.
Example 1: If the short hand points to 7 and the long hand points to 12, the time is 7 o'clock. This is the time many of us get ready for school!
Example 2: If the short hand points to 1 and the long hand points to 12, the time is 1 o'clock. Time for lunch! Maybe some delicious ugali na sukuma wiki.
Image Suggestion: A warm, inviting picture of a Kenyan family sitting around a table for lunch. A clock on the wall clearly shows the time is 1 o'clock. The food on the table includes local dishes like ugali and sukuma wiki.
Telling Time: "Half Past" (Na Nusu)
What happens when the long minute hand travels all the way to the bottom, to the number 6? It has gone halfway around the clock! So, we say it is "half past" the hour.
When this happens, the short hour hand will also have moved. It won't be pointing directly at a number, but will be halfway between two numbers.
Example: If the long hand points to 6 and the short hand is halfway between 4 and 5, the time is half past 4. This is a great time to finish your homework and go outside to play!
A Short Story:Amina loves visiting her shosho (grandmother) at the shamba. She arrives at 2 o'clock. Her shosho tells her, "Amina, we will water the maize at half past 2." Amina watches the clock. She sees the long minute hand move from the 12 all the way down to the 6. The short hour hand moves a little bit, right between the 2 and the 3. "Shosho, it's time!" she shouts happily. And off they go!
How We Measure Time
Just like we measure length in metres, we measure time in different units. The most common ones are seconds, minutes, and hours.
- A second is very short. Clapping your hands once takes about one second.
- A minute is longer. It is made of 60 seconds. It takes a few minutes to wash your hands properly.
- An hour is even longer! It is made of 60 minutes. Your favourite class in school might last for about one hour.
Let's put it all together!
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
Let's Do Some Time Math!
We can add and subtract time. Let's try a simple problem.
Benson gets into a matatu at 3 o'clock to go to the market. The journey takes 1 hour. What time will Benson arrive at the market?
We can solve this by adding the time!
Step 1: What is the starting time?
Start Time = 3 o'clock
Step 2: How long is the journey?
Time Taken = 1 hour
Step 3: Add the time taken to the start time.
3 o'clock + 1 hour = 4 o'clock
Answer: Benson will arrive at the market at 4 o'clock!
Great Work, Time Master!
Wow! You have learned so much today. You can now tell the time for "o'clock" and "half past", you know the units we use to measure time, and you can even do simple time math. You are brilliant!
Your Fun Activity:
Tonight, before you go to bed, draw a picture of a clock. Make the hands show the time you go to sleep. Show it to your family and tell them the time. Keep practicing, and soon you will be able to read any time on the clock!
Image Suggestion: A cheerful Kenyan child proudly showing their drawing of a clock to their smiling parent or guardian in a cozy home setting.
Habari Mwanafunzi! It's Time for Time!
Hello there, brilliant student! Have you ever noticed how your day is full of different activities? You wake up, eat breakfast, rush to school, learn amazing things, play with friends, go home, and then sleep. But how do we know when to do all these things? We use something magical called TIME! Today, we are going to become time experts together. Are you ready? Let's go!
Meet Juma: Every morning, Juma hears the rooster crow. That's his first clock! Then, he hears the school bell ring. That's another way to tell time! Time is all around us, helping us organise our day.
The Clock - Our Friendly Time-Teller!
The most common way we tell time is by looking at a clock. A clock has a face with numbers and two very important hands. Think of them as two runners on a race track!
- The Short Hand is the Hour Hand. It's a bit slow and steady, and it points to the hour.
- The Long Hand is the Minute Hand. It moves faster and shows us the minutes.
Let's look at a simple clock face:
12
11 1
10 2
9 3
8 4
7 5
6
Image Suggestion: [A friendly, colourful cartoon wall clock with a smiling face. The short "Hour Hand" should be thick and blue, and the long "Minute Hand" should be thin and red. Both hands should be clearly labeled.]
Telling Time: "O'clock"
This is the easiest time to tell! When the long minute hand points straight up to the number 12, we say it is "o'clock". To know which hour it is, we just look at where the short hour hand is pointing.
For example:
12
11 1
10 2
9 O----->3 (Short hour hand points to 3)
8 4
7 5
6

When you see this, it is 3 o'clock. This might be the time you finish your last lesson before going home!
A Day at School in O'clock!
- At 8 o'clock, the bell rings for classes to start.
- At 1 o'clock, it's lunchtime! Yum!
- At 4 o'clock, the school day is over and it's time to go home.
Half Past the Hour
What happens when the long minute hand has travelled halfway around the clock? It points straight down to the number 6. When this happens, we say it is "half past" the hour.
The short hour hand will not point directly at a number. It will be halfway between two numbers.
For example:
12
11 1
10 2
9 3
8 .---- 4 (Short hour hand is between 8 and 9)
7 5

This clock is showing Half Past 8. This is often the time for the morning parade at school.
Units of Time: From a Blink to a Birthday!
We can measure time in different amounts, just like we can measure sugar in spoons or sacks! Here are the most important units:
- 60 seconds make 1 minute. (Try counting to 60, that's one minute!)
- 60 minutes make 1 hour. (This is usually how long one lesson lasts.)
- 24 hours make 1 day. (A full day and a full night.)
- 7 days make 1 week. (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday!)
- 12 months make 1 year. (From your last birthday to your next one!)
Time in Our Kenyan Life
We use time for everything in Kenya! It helps our country run smoothly.
Catching the Matatu: Wanjiru's mum has to be at her job in town by 8 o'clock. She knows the matatu passes her stage at half past 6, so she must be ready on time or she will be late!
Market Day: In many villages, market day is on a specific day of the week, like Tuesday. Families know that every 7 days, they will go to the market to sell their crops and buy supplies.
Image Suggestion: [A vibrant, sunny scene of a bustling Kenyan open-air market. A mother and child are looking at fresh mangoes. In the background, a large, simple clock tower shows the time as 11 o'clock.]
Let's Do Some Simple Time Maths!
You can even add time! Let's try a simple problem.
Problem 1: Your favourite cartoon starts at 5 o'clock. It is 1 hour long. What time will it finish?
Start Time: 5 o'clock
Add: + 1 hour
-----------------------
Finish Time: 6 o'clock
Wow, that was easy! The cartoon will finish at 6 o'clock.
Problem 2: You go out to play football at 4 o'clock. Your mum tells you to play for 30 minutes (which is half an hour). What time should you come back inside?
Start Time: 4 o'clock
Add: + 30 minutes
---------------------------
Finish Time: Half Past 4
You should be back inside at Half Past 4. Well done!
You are a Time Master!
