Bronze: Khadija says this number could be 40 because it has four tens.

Silver: jessica has the largest number because she have two tens and 9 ones (10+10+9=29). This is bigger than 27 ones which khadija has said is 27.

Gold: yes habib is right because we are not changing the ones, just the tens.

Platium: 10+10+10+10+10+10+10=70 which is 7 lots of 10. Khadija added 32 to 70 and ended up with 102p. Since there are 100 pennies in a pound, isla is right. she has more than a pound.

Bronze:
It could be 40, 44, 47 or 49 because they all have 4 tens.

It can’t be 30, 50, 10 because they are all tens but not 4 tens.

Silver:
Jessica had the most because she has 29 ones and faith only had 27 ones.

Gold:
Yes habib is right because the ones only change when you add ones but if you only add tens it stays the same.

Platinum:
Yes she is correct because she has 102p now and that is £1.02.

Four ones means 10+10+10+10=40
20+20=40
30+10=40
35+7=42
20+30=50

Jessica has two tens and 9ones that means its 29 and its bigger than 27.

When we add ten to any number the ones always stay the same like,32+10=42
50+10=60

Platium

7lots of 10p =70p

Bronze  
These numbers have four tens 40, 41, 42,43 ,44,45,46,47,48,49
Any number below 40 and any number above 49 can’t have four tens like 32 or 65
Silver
Jessica has the largest number because Faith has 27 ones and Jessica has 29 ones which is two ones more than Faith has.
Gold  
Yes Habib right, the number will go up by 10 keeping ones the same number 
52+10 = 62
2 at the one position stay the same 
64+ 10=74 
4 at the one position stay the same 
Platinum  Isla is right, she has total of £1.02 32p + 10+10+10+10+10+10+10 = 70p – total 102p 
So Isla has more than £1

jessica has a larger number because she has 2 tens which is twenty and 9 ones which is larger than 2 tens and 7 ones.
gold
when you add ten to a number the ones will stay the same because the tens are changing not the ones which means habib is correct.
platimum
isla is correct because 70 add 32 is 102
which means £1.02

Bronze
10+10+10+10=40
20+20=40
35+5=40

40+7=47
20+4=24
44+10=54

27+29=56
Because there are 2 tens in each number we add those first to make 40.We then add 9+7=16 and then we add the two numbers to make 56.

When you add tens to any number the ones always stay the same:
26+10=36
110+10=120
39+10=49
when these numbers are added to ten then the ones column stays the same.

(Bronze)

It could be 43, 46, 48.
It can’t be 32, 55, 62.

(Silver)
Jassica has the largest number because she has two tens and nine ones so the whole number will become 29, whereas Faith had 27 which is two less then 29.
Therefore 29 is bigger then 27.

(Gold)

Habib is correct because if you keep adding the number to 13 the ones stays the same. Examples:
8+10=18
5+ 10=15

Bronze:

The number could be 40 because that has 4 10’s: 10+10+10+10 = 40

Or it could be: 44 because that has 4 10’s plus 2 1’s: 10 +10+10+10 + 1 + 1 +1+1 = 44

Or it could be 46 because that has 4 10’s and 7 ones 10+10+10+10+1+1+1+1+1+1+1= 47

The number can’t be 50 because that has 5 10’s = 10+10+10+10+10

Or it can’t be 56 because that 5 10’s and 6 1’s = 10+10+10+10+10+1+1+1 +1+1+1= 56

Or it can’t be 61 because that has 8 10’s and a two 1’s 10+10+10+10+10+10+10+10+10+1+1 = 82

Silver:

Jessica has the highest number because the total of her number is 29 because she has two 10’s and 9 1’s – 10+10+1+1+1+1+1+1+1+1+1 = 29

Faith only has 27 because she has 27 1’s.

Gold:

Yes Habib is right. For example

29+10 = 39 in this example 9 is in the one column which stays the same

15+10 = 25 in this example 5 is in the one column which stays the same.

Silver-
Jessica has the largest number because 2 tens and 9 ones total 29 which is bigger than 27
Gold-
Yes, example 22+10=32 and 92+10=102
Platinum
Yes – 7 lots of 10p is 70p – add this to the 37p she already has equals 107p. As 100p equal £1, 107p is more than £1

Gold:
Habib is right because if you 13 and you add 10, then the 1 changes to 2 but the 3 stays the same. The 3 is the “1s”.

Bronze:
4 tens make 40

Silver:

Jassica has the most because 2 tens and 9 ones are bigger than 2 tens and 7 ones.

Gold:

Habib is not right because if you have for example 10+ 2 = 12 the ones is change from 0 to 2.

Platinum:

Isla has 32p and gets 10p 7 times that means she has 32p + 70p = 102p
1pound is 100p
Isla is correct because she has more than 100p .
