Subtraction eggs

Oh no Year 1... look what's happened to my eggs! 

I dropped them on the floor. I wonder how many I have left?

How many eggs did I have to begin with?

How many eggs have broken?

How many eggs am I left with?

Now, draw a picture to show what has happened to my eggs.

Then, write a number sentence to show what has happened to my eggs.

Which symbol will you use?
