Jambo! Let's Go on a Time Adventure!
Have you ever wondered why the sun wakes up in the morning, you go to school, and then the moon comes out to play at night? It’s all because of time! Time helps us know WHEN things happen. It is like a big, invisible river that is always flowing. Today, we are going to become time experts! Are you ready?
Meet Our Friend: The Clock!
The most common way we see time is by looking at a clock. There are two main types of clocks. Let's look at the first one, which has a face and hands, just like you!
The Analog Clock (The Clock with a Face)
This clock has two very important hands:
- The Short Hand is the Hour Hand. It moves very slowly.
- The Long Hand is the Minute Hand. It moves faster than the hour hand.

(Short Hour Hand)
When the long minute hand points straight up to the number 12, we say it is "o'clock". We just need to look at where the short hour hand is pointing!
Example Scenario: It's morning in Nairobi! The sun is shining, and it's time to get ready for school. You look at the clock. The short hand points to 7 and the long hand points to 12. That means it is 7 o'clock! Time to brush your teeth!
Image Suggestion: A brightly illustrated cartoon image of a cheerful, smiling sun rising over the Nairobi skyline. In a classroom, a diverse group of young Kenyan children in school uniforms are excitedly pointing at a large, colorful analog clock on the wall showing 7 o'clock.
Half Past the Hour
What happens when the long minute hand travels all the way down to the number 6? It has gone halfway around the clock! We call this "half past" the hour.

(Long Minute Hand pointing to 6)
Example Scenario: Mwalimu says, "Break time!" You run out to play. The clock's short hand is a little past 10, and the long hand is pointing to 6. It is half past 10. Time for your snack!
The Digital Clock
This clock is very easy to read. It shows you the numbers directly! The number on the left is the hour, and the number on the right is the minutes.

| 10:30 |
+-----------------+
This digital clock shows the same time as "half past 10". So easy!
Bigger Pieces of Time: Days, Weeks, and Months!
Time is not just about hours and minutes. We also measure it in bigger chunks using a calendar.
Days of the Week
There are 7 days in every week. Let's sing them together!
- Sunday (Jumapili)
- Monday (Jumatatu)
- Tuesday (Jumanne)
- Wednesday (Jumatano)
- Thursday (Alhamisi)
- Friday (Ijumaa)
- Saturday (Jumamosi)
Months of the Year
And there are 12 months in a year! Some months are for planting shamba (the farm) when the long rains come, and some months are sunny and dry.
Image Suggestion: A vibrant, illustrated calendar page for the month of April. The illustration shows a lush green Kenyan landscape with children happily planting seedlings in a shamba as gentle rain falls. The art style should be colorful and friendly, like a children's storybook.
Let's Do Some Time Maths!
Time helps us solve problems. Let's try one!
Story Time Problem: Amina takes a matatu from her home in Nakuru to visit her shosho (grandmother) in Naivasha. She leaves at 3 o'clock in the afternoon. The trip takes exactly 1 hour. What time does she arrive?
Let's find out step-by-step!
Step 1: What time did she start?
> 3 o'clock
Step 2: How long was the trip?
> 1 hour
Step 3: We need to add the time. What is 1 hour after 3 o'clock?
> We move the hour hand forward by one number.
> 3 o'clock ---> 4 o'clock
Answer: Amina arrives at her shosho's house at 4 o'clock!
Great Job, Time Explorer!
Wow! You have learned so much about time today. You learned how to read a clock, the days of the week, and even how to solve a time problem. Remember, time is your friend that helps you plan your fun activities, your learning, and your rest. Keep looking at clocks and calendars, and soon you will be a Master of Time!
Habari Mwanafunzi! Welcome to the Wonderful World of Time!
Have you ever wondered why you wake up when the sun is out, go to school, play with your friends, and go to sleep when the moon is shining? It's all because of time! Time helps us know when to do things. Today, we are going to become time experts, and our special tool is the clock!

Our Friend, the Clock Face
Look at a clock. It's like a round face with numbers and two hands. Let's learn about its parts!
- The Numbers: It has numbers from 1 to 12, just like you can count!
- The Short Hand (Hour Hand): This is the slow and strong hand. It tells us the hour. Think of it like a tortoise, moving slowly but importantly.
- The Long Hand (Minute Hand): This is the faster, longer hand. It tells us the minutes. It's like a speedy hare, moving around the clock much faster than the hour hand.

Telling Time: "O'clock" (Saa Kamili)
When the long minute hand points straight up to the number 12, we say it is "o'clock". It's the start of a new hour! To know which hour it is, we just look at where the short hour hand is pointing.
- If the short hand points to 7 and the long hand points to 12, it is 7 o'clock. Time to get ready for school!
- If the short hand points to 1 and the long hand points to 12, it is 1 o'clock. Time for lunch break!
Story Time: Kamau's grandmother in the village always listens to the radio news. The news starts exactly when the short hand is on 8 and the long hand is on 12. What time is the news? That's right! 8 o'clock!
Telling Time: "Half Past" (Na Nusu)
What happens when the long minute hand has travelled halfway around the clock? It points down to the number 6. When this happens, we say it is "half past" the hour.
The short hour hand will also have moved. It won't point directly at a number, but will be halfway between two numbers. For example, at half past 2, the hour hand is halfway between 2 and 3.
// This clock shows Half Past 2 (2:30) \\

Let's Do Some Time Maths!
Time doesn't stand still! We can add hours to find out what the time will be later. It's as easy as counting!
Scenario: Wanjiku goes to the shamba with her father at 9 o'clock in the morning. They work for 2 hours. What time will they finish?
Let's calculate it step-by-step:
Step 1: What is the starting time?
Start Time = 9 o'clock
Step 2: How many hours do we add?
Add = 2 hours
Step 3: Let's count forward from 9.
One hour after 9 o'clock is 10 o'clock.
Two hours after 9 o'clock is 11 o'clock.
9 + 2 = 11
Answer: They will finish at 11 o'clock!
See? You just did time mathematics! Well done!
Days and Months: Bigger Pieces of Time
Time isn't just about hours and minutes. We also measure it in days, weeks, and months!
The 7 Days of the Week
A week is made of seven special days. Five are school days and two are for the weekend!
- Monday (Siku ya kwanza shuleni!)
- Tuesday
- Wednesday
- Thursday
- Friday (Yay, mwisho wa wiki unakaribia!)
- Saturday (Time to play and do chores!)
- Sunday (Time for family and rest.)
The 12 Months of the Year
A whole year is very long! It is made of 12 months. Each month has many days.
- January
- February
- March
- April (Sometimes the long rains begin!)
- May
- June
- July
- August (School holidays!)
- September
- October
- November
- December (Christmas and end-of-year holidays!)
You are a Time Master!
Wow, look at everything you have learned today! You are doing an amazing job.
- You learned about the hour hand and the minute hand.
- You can tell the time at "o'clock" (saa kamili).
- You can tell the time at "half past" (na nusu).
- You even know the days of the week and months of the year!
Keep looking at clocks everywhere you go – in your classroom, at home, or at the duka. The more you practice, the easier it will become. You are on your way to becoming a true Time Master!
Habari Mwanafunzi! Let's Learn About Time!
Hello there, bright student! Have you ever wondered why you wake up when the sun comes up, eat lunch in the middle of the day, and go to sleep when it gets dark? It's all because of TIME! Today, we are going on an exciting journey to become masters of time. Are you ready? Let's go!
Meet Our Friend, the Clock!
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.
- The Short Hand is the Hour Hand. It moves slowly, like a tortoise taking a stroll. It tells us the hour.
- The Long Hand is the Minute Hand. It moves faster, like a speedy cheetah. It tells us the minutes.
Let's look at a simple clock face:
12
|
9 ---+--- 3
|
6
Think of it like this: When you are at school, the short hour hand points to the class you are in (like Grade 2), while the long minute hand tells you what you are doing right now (like listening to the teacher!).
Telling Time: "O'clock"
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!
Image Suggestion: A vibrant and colourful cartoon illustration of a smiling, friendly clock character. The clock's long minute hand is pointing directly at the 12, and its short hour hand is pointing at the 8. Around the clock, a cheerful Kenyan school child in uniform is packing their school bag, with a sunny window showing a rural landscape in the background.
For example:
- If the short hand is on 7 and the long hand is on 12, the time is 7 o'clock. Time to wake up and help with the shamba chores!
- If the short hand is on 1 and the long hand is on 12, the time is 1 o'clock. It's lunchtime! Time for some delicious ugali and sukuma wiki.
Telling Time: "Half Past"
What happens when the long minute hand travels halfway around the clock and points down to the number 6? We call this "half past". It means 30 minutes have passed since the "o'clock" hour.
Imagine a delicious, round chapati. If you cut it exactly in the middle, you have two halves. The minute hand does the same thing on the clock face! When it goes from 12 to 6, it has gone "half way".
For example:
- When the short hour hand is a little bit past 10 and the long hand is on 6, the time is half past 10. This is break time at school! Time to play and have a snack.
- When the short hour hand is a little bit past 4 and the long hand is on 6, the time is half past 4. School is over, and it's time to head home.
The Building Blocks of Time
Time is made of small pieces that build up into bigger ones, just like bricks building a house!
60 Seconds = 1 Minute
60 Minutes = 1 Hour
24 Hours = 1 Day
A second is very short! You can try counting "One mkokoteni, two mkokoteni..." and each one is about a second. A minute is longer, about the time it takes to wash your hands properly. An hour is much longer, like one lesson in your class!
Days of the Week and Months of the Year
Time also helps us organise our lives into days and months.
Days of the Week (Siku za Wiki)
- Jumatatu (Monday): The start of a new school week!
- Jumanne (Tuesday): We continue learning new things.
- Jumatano (Wednesday): Mid-week! Maybe it's games day.
- Alhamisi (Thursday): Getting closer to the weekend.
- Ijumaa (Friday): The last day of the school week!
- Jumamosi (Saturday): Market day for many families!
- Jumapili (Sunday): A day for rest, family, and church.
Image Suggestion: A colourful, illustrated weekly calendar for a Kenyan child. Each day has a small icon: a schoolbook for Monday-Friday, a basket of vegetables for Saturday, and a picture of a family or church for Sunday. The style is playful and easy to read.
Let's Practice with a Story!
Here is a short problem to see how well you understand time.
Amina's family wants to travel by matatu from Mombasa to Nairobi. The matatu leaves at 8 o'clock in the morning. The journey takes 3 hours. What time will they arrive in Nairobi?
Let's solve it together step-by-step!
Problem: A matatu leaves at 8 o'clock. The journey is 3 hours long.
When will it arrive?
Step 1: Write down the starting time.
Start Time = 8 o'clock
Step 2: Count forward 3 hours from the start time.
- 1 hour after 8 o'clock is 9 o'clock.
- 2 hours after 8 o'clock is 10 o'clock.
- 3 hours after 8 o'clock is 11 o'clock.
Answer: Amina's family will arrive in Nairobi at 11 o'clock!
Hongera! You are a Time Expert!
Well done! You have learned so much about time today. You can read a clock, you know about days of the week, and you can even solve time problems. Keep practising by looking at the clock at home and at school. Sasa wewe ni mtaalamu wa wakati! (Now you are a time expert!)
