What is the same about all 2-Digit
numbers?
Yes! They all have ONE 10
and a unit
Can you 15 by 3?
15 3 = ? 3.. 6.. 9.. Yes it’s 5!
24 4 = ? 4.. 8.. 12..
Yes it’s 6!
If you know your tables ..
You can divide!
How about 16 4?
How many 4s in 16?Count in 4s
Until you reach 164.. 8.. 12.. 1616 4 = 4
How about 21 3 =?How many 3s in 21?
3.. 6.. 9.. 12.. 15.. 18.. 21..= 7
Same as 7 x 3 =21
You have turned into x
Well Done !Now you are ready to divide
a 2-Digit number.Try theseand ……
Good Luck!
Find the answers:• 24 3 =• 18 2 =• 30 5 =• 16 8 =• 50 10 =• 27 9 = Can you check your
answer?• 44 11 = Use the inverse
operation.
