Topic 1: Numbers

4. Aims
1. Know Numbers upto 1 Million
2. Recognize
Group of 10 hundreds = 1 thousands
= 1000
Group of 10 ten thousands = 100 000
Group of 10 ten millions = 100 millions
= 100 000 000

5. Numbers up to 1 Million
• 1 Block = 1 one
• Group of 10 blocks = 1 ten

6. Ahmad has 26 blocks
• How many tens and ones are in 26?
2 6
26 = 2 tens 6 ones
26 = 20 + 6
In words , we read
and write it as
“twenty six”

7. When we group 10 tens together, we
get 1 hundred

8. How many hundreds, tens and ones
are there in 241?
2 4 1
There are 2 hundreds, 4 tens and 1 ones
In 241.

9. Look at these coins. The numbers on
each coin shows its value.

10. Let’s write 241 according to the
“PLACE VALUE”
of its digits.
241 = 2 hundreds + 4 tens + 1 ones
= 200 + 41 + 1
In words , we read and write it as
“Two Hundred and Forty One”.

11. Try it
• Identify hundreds, tens and ones in the

12. Group of 10 Hundreds = 1 thousands
= 1000

13. There are 3254 students in Ali’s Schools
3 2 5 4
There are 3 thousands 2 hundreds 5 tens and 4 ones in the numbers 3254
Digit 3 is in the thousands Place 3000
Digit 2 is in the hundreds place 200
Digit 5 is in the tens place 50
Digit 4 is in the ones place 4
3254 = 3000 + 200 + 50 + 4
In Word, we read and write it as
“Three thousands two hundreds and fifty four.”
There are three thousands, two hundreds and fifty four
students in Ali’s Schools
