Adding on within 20

 Yesterday in maths, the children were learning to add on within 20. 

To do this, they were using a 20 frame telling a First, Then and Now story. 

For example: 

First, there were 10 children on the bus. 

Then, 6 more children got on the bus. 

Now, there are 16 children on the bus. 

The children were counting on from 10 to get their answer.
