Bronze:
Add two even numbers together will always make an even number?
True because 2+2=4 18+18=36 4+4=8 8+8=169+9=18. And there all even numbers.
Plantium:
2+3+4=9
3+4+5=12
4+5+6=15
5+6+7=18.
Bronze:
Yes it is true because when whee add two even numbers together it will always make an even number.
For example
8+6=14
10+4=14
Silver:
10+26=36
9+27=36
8+28=36
7+29=36

I noticed that it has a patern and the answer is a 3 timetable.
1-true for example 64+32=96
2-
34+2=36
35+1=36
18+18=36
30+6=36
20+16=36

3-
20p+5p=25p
10p+10p+5p
10p+5p+5p+1p+1p+1p+1p+1p=25p
50p-25p=25p
20p+2p+2p+1p=25p
10p+5p+5p+5p=25p
Platinum
4+5+6=15 this pattern is of odd numbers.
Platinum=This pattern is adding 3 each time

Platinum
4+5+6=15,So 9,12,15 then 18,21,24,27 that means counting in 3 .
Bronze
Correct because in the two times tables it gains up to an even number. So the result can always be divided by two.
4+6 = 10 (even), 10/2 = 5
6+8= 14 (even), 14/2 = 7
8+4 = 12 (even), 12/2 = 6
Silver
1+35=36 11+25=36 21+15 = 36
2+34=36 12+24=36 22+14 = 36
3+33=36 13+23=36 23+13 = 36
4+32=36 14+22=36 24+12 = 36

5p+5p+5p+5p+5p =25p
10x2p + 5x1p=25p
15x1p+ 5x2p = 25p
50p – 10p – 10p – 5p = 25p
10p + 10p + 10p – 5p = 25p
Platinum
4+5+6 =15, then 18 and then 21 because the pattern is counting in 3rs
9,12,15, 18, 21, 24, 27, 30, 33, 36, ….
Bronze
Its true if you add two even number the answer will be even number.

I notice the answers are adding in 3 (15,18,21,24,27,30,33,36)
Gold
20p + 5p = 25p
10p + 10p + 5p = 25p
5p + 5p + 5p + 5p + 5p = 25p
20p + 2p + 2p + 1p = 25p
10p + 10p + 2p + 2p + 1p = 25p
( I helped Faris with this as he really struggled with all the challenges)

2+3+4=9
3+4+5=12
4+5+6=15
5+6+7=18
6+7+8=21
7+8+9=24
I notice the number sentences start with the middle number then the next number after that and if you look at all the numbers together you can see a pattern in the columns.
All the number sentences end in the 3 times table. I used my Time table
card.
1 x 3 = 3
2 x 3 = 6
3 x 3 = 9
4 x 3 = 12
5 x 3 = 15
6 x 3 = 18
7 x 3 = 21
8 x 3 = 24
9 x 3 = 27
10 x 3 = 30
11 x 3 = 33
12 x 3 = 36

The next number number in the sequence would be 15.
The pattern I noticed was the answers going up in 3s.
Rexford
Bronze – yes it’s fact because even numbers can always be split into 2 equal numbers.
E.g
10+10=20, if you split 20 you have two 10’s. 2 +2 = 4
Silver
30+6=36

Sorry Freya attempted this
Bronze.
Any even number can plus any other even number will always equal an even number.
For example 2+2=4 8+8=16 6+6=12 10+10=20 12 +12=24 14+14=28 16+16=32
18+18=36 20+20=40

I noticed that it has a pattern and it goes in our 3 times tables.
Bronze.
Any even number can plus any other even number will always equal an even number.
For example 2+2=4 8+8=16 6+6=12 10+10=20 12 +12=24 14+14=28 16+16=32

Bronze: yes if we add two even numbers together the answer will be always even,so this statement is true e.g.
4+2=6 so 4 is a even no and 2 is a even no too so answer is even aswel which is 6.
Silver:
We can make 36 number by adding up different numbers,
1+35=36
2 +34=36
3+33=36
4+32=36
5+31=36
6+30=36
7+29=36
8+28=36
9+27=36
10+26=36
Platinum:
4+5+6=15
7+5+6=18
It shows we r adding 3 up in every answer so it is a 3 times table.
Bronze.
The answer is true because even is 2,4,6,8,10,12,14,16,18,20,22,24.
Silver.
31+5=36, 32+4=36,37-1=36,10+10+10+6=36
Gold.
10p+10p+5p=25p, 20p+5p=25p,10p+10p+2p+2p+1p=25p
Platinum.
4+5+6=15
I’ve noticed there is a pattern and the pattern is (2,3,4,5) (3,4,5,6) (4,5,6,7)
Bronze:
It is true because:
2 + 2 = 4 and 12 + 12 = 24. So, if we add any even numbers together it will always equal an even number.
Silver:
Some ways to make 36 are:
36 + 0
35 + 1
34 + 2
33 + 3
32 + 4
31 + 5
30 + 6
29 + 7
28 + 8
27 + 9
26 + 10
Gold:
Some ways to make 25p are:
10p + 10p + 5p
50p – 10p – 10p – 10p + 5p
5p + 5p + 5p + 5p + 5p
10p + 10p + 1p + 1p + 1p+ 1p + 1p
10p + 10p + 2p + 2p + 1p
Platinum:
2 + 3 + 4 = 9
3 + 4 + 5 = 12
4 + 5 + 6 = 15
5 + 6 + 7 = 18
6 + 7 + 8 = 21
I notice that it is going in number order like 1 2 3. I also notice adding on 3 every next sum.
Bronze – It is true because even numbers can always be split into 2 equal numbers.
example – 10+10=20, if you split 20 you have two 10’s.
Silver
31+5=36
17+19=36
21+15=36
33+3=36
10+26=36

Platinum
2+3+4=9
3+4+5=12
4+5+6=15
5+6+7=18
The difference between all the answer is 3.
Bronze:
1- It is true. This is because 2+2 equals 4 and 10+10 equals 20.
Silver:
1- 26+10
31+5
21+14
34+2
35+1
33+3
24+12
Gold:
10p+10p+5p
5p+5p+5p+10p
50p-10p-10p-5p
Platinum:
1- 4+5+6 equals 15.
The pattern is that the last two numbers get moved on and added with the next biggest number.
The next sequence would be 5+6+7.
