MATHS HOMEWORK - Due 15.12.17 - Please comment on the blog below.

Can you solve this number problem?

Some cakes have been eaten.

 

Two cakes are left. 

How many cakes could there have been, and how many could have been eaten to be left with 2?

Can you think of three different ways? 

For example...

I could have had 5 cakes and have eaten 3 to be left with 2.

5 - 3 = 2

I could have had 8 cakes and have eaten 6 to be left with 2. 

8 - 6 = 2

I could have had 10 cakes and have eaten 8 to be left with 2. 

10 - 8 = 2

7-5=2

We bought 4 cakes and mummy & daddy have eaten 2 so another 2 been left.
4-2=2

I could have had 3 cakes and my little sister Lara have eaten 1 so 2 been left.
3-1=2
