If we look at the picture, there are many ways to figure this out, but our goal is to understand the situation of addition. So, when you look at the picture, you know that we need to use ‘addition’ to get the answer.

Teacher 2

Firstly, the students have to be able to tell that there are different numbers of children playing at these two spots. Then, they have to see how many children at the sand tray and how many at the slider. Finally, if we want to know how many children there are in the playground, what can we do? Can you tell me?

Teacher 1

Yes. And the students will say put the numbers of the children at both spots together or count the total number. Is that right? But, we have to tell them that they may not count.

Teacher 2

They have to understand from the picture that it is about addition or multiplication. How can you put this into a symbolic sentence? How can you tell me how many children there are. They will use the method that they have learned before, such as counting by 2 at a time, 5 at a time, 10 at a time, or counting to 10 first.
