Hannah started putting counters
into 10 frames to help her add. Eight plus seven plus two. What is the total?
We can see that Hannah has already
put eight counters into a 10 frame. There are two empty spaces in this
10 frame. So we could add the two green
counters. Now, we just need to add the seven
blue counters to the other 10 frame.
Now, all we need to do is count how
many counters Hannah has altogether in her 10 frames. The first 10 frame is full, which
means it has 10 counters. And the second 10 frame has seven
So we need to add together 10 plus
seven. So the answer is 17.
