Maths

In maths we have been learning about addition.
We have been adding 1 and 2, to numbers up to 12.
To help us, we have been using bead strings. 

We also thought about passengers on a bus...

If there are 7 passengers sitting on a bus, and two more get on, how many are on the bus now? 

How can we write this as a mathematical sentence? 

7+2=9            Easy!
