Elise, Elise.
We have a problem on the board, who will read it?
Who can read the problem on the board?
-Who can read the problem on the board? -Yes, Evelyn Musa.
If a lorry covered 11 kilometers,
130 meters,
26 centimeters,
on the first day,
9 kilometers, 728 meters,
57 centimeters, on the second day,
59 kilometers, 62 meters, 53 centimeters on the third day,
and 17 kilometers, 71 meters,
45 centimeter, on the fourth day...
What was the total distance covered in the four days?
Again.
The last part.
What was the total distance covered in the four days?
In the four days, okay, very good. Clap hands for her.
-I'm erasing it. -Don't forget the information!
No!
Let' see if someone will forget this...
Now, in the four days, a lorry covered such distances.
So, to make it short, let us write kilometers, meter and centimeter.
Written as it is...
a kilometer, meter and centimeters.
We know that we have missed some units.
There are some units missing from the centimeter.
To get to the kilometer, we have skipped a number of units.
-Right?-Yes. -OK.
On the first day, tell us, how many kilometers were covered on the first day?
11 kilometers.
11 Kilometers. It's as if you are ill...
-First day? -11 kilometers.
100 and 30 meters.
-130... -Meters... 26 centimeter.
Okay, now...
If you know the answer,
just raise up your hand.
Don't you all go at once!
This is embarassing.
Yes, on the second day?
Agness Kalusi
9 kilometers.
I am talking to you Agness Kalusi, on the first, the second day...
728 meters.
728, 57 centimeters.
Some of you are scared of the camera.
57? Okay, better - 57.
On the third day?
Yes, Gladys.
59 kilometers.
62 meters.
"62"... 62 meters.
53 centimeters.
And on the 4th day?
Natasha.
-17 kilometers. -17 kilometers.
-71 meters. -71 meters.
-45 centimeters. -What?
-45 centimeter. -Okay.
This is the second day,
third day,
and fourth day.
Total distance covered?
It will be addition. We've already mentioned that we're missing some units.
So, let us add.
-6+7? -13.
-13+3? -16.
-16+5? -21. -We write 1.
-2+2? -4.
-2 that we carried over from 21, right? -Yes!
What is it?
We have kept 2 from 21, right? -Yes.
-So, 2+2? -4
-4+5? -9
-9+5? -14
-14 +... -18 -18.
We have got 181 centimeters.
How many centimeters make 1 meter?
How many centimeters make 1 meter?
Yes, Steven.
1 centimeters...
Come on, don't laugh. Yes, Steven.
1 centimeter makes 1 meter.
Sir, Sir...
Steven, Steven, Steven...
Yes, Eliza Kachele. Sit down.
-100 centimeters. -100 centimeters equals one meter.
Why is it that 100 centimeter equals 1 meter?
Why is it that 100 centimeter equals 1 meter
-Yes, Edith. -We multiply 10 by 10.
-Times ten. -If we multiply by 10 are we going to get 100?
Yes, we will start with millimeter, we will have 1,10,1,10 mm...
Make 1 cm... 1, 10 cm, 1, 10 meter make 1...
10 mm equals 10 cm. 10 mm equals to 1...
We can't understand? No.
Not so? Yes. We multiply 10 by 10.
Why do we multiply 10 by 10?
-It is because we have skipped a unit. What unit have we skipped? -Decimeter
Decimeter, very good. Clap hands for him.
We have skipped decimeter-centimeter, decimeter, then meter.
That is why we are multiplying by 10.
10 times 10 is equal to 100.
100 centimeter equals 1 meter.
That is why we have skipped decimeter.
-Is it clear Edith? -Yes.
"Yes".
OK, now we divide this by 100.
-What are we dividing by? -100.
100, because 100 cm equals 1 meter.
We want to get 1 meter.
These numbers don't add up to 100 cm.
Which means they don't add up to 1 meter.
-Steven, is it clear? -Yes...
...yes.
OK, 181 divide by 100. What is the answer?
Sir, Sir, Sir...
-Give him time. -1
1, so we write 1.
Instead of writing 1 here...
We'll write it over here to make the counting easier.
1 times 100 is what?
-100 -Huh? -100.
181 minus 100?
-Yes. -81.
Now, this 81 is less than a hundred.
Less than 100. We will leave this as centimeters.
So we write down 81 here as 81 centimeters.
But, bear in mind that we carried over the one, which is...
A meter. We will put it with the other meters.
-Right? -Yes.
Yes, and don't just be quiet!
OK.
-So, let's add these meters. 0 plus 8? -8.
-Plus 2? -10.
-Plus 1? -11.
-11+1 we carried over? -12.
Which means that we are now done with 1 because we have added it.
Now, 12 and we have carried 1.
-1+3? -4.
-Plus 2? -6. 6+6? -12.
12+7?
17, 15, 19...
Huh?
19, 19.
9 and we have carried over 1.
1+1? 2
+7? 9
How many meters do we have?
Yes, Tinkhani.
-1000. -Is this 1000?
-No. -So where did the 1000 come from?
Sir, Sir, Sir...
-Where did the 1000 come from? -Sir, Sir, Sir...
Yes, Edith.
-100. - Again is this100? - No, no.
Sir, Sir, Sir...
-Yes, Thokozani? -900
-Huh? -900
-Zachariah? -992
-Not so? Yes.
-Is this 900? -No.
-Is this 100? -No.
This breaks my heart.
How many meters make 1 kilometer?
How many meters make 1 kilometer?
-Yes, Memory. -1,000.
Now, do we have enough to convert this to kilometers?
-No. -We do not have 1,000.
This means we will leave it as it is.
Or we could have converted this
to decameters or hectameters.
In that case, it would have been enough.
But because we went straight from meters to kilometers,
which is a thousand,
the result of our addition does not equal 1000.
So, we just write 992 because we don't have 1000.
-Do we agree? -Yes. -"Yes".
Now, we have to add the kilometers.
-1+9? -10.
-10+9? -19.
-19+7? -26.
We write down 6 and take over 2.
-2+1? -3.
-3+5? -8.
8+1?
