The question
Question: 60 is 5 tens and how many ones?
60 = 5 tens □ ones
1 Show it with blocks
A ten is 10 ones stuck together.
60 is 6 tens and 0 ones.
2 Break a ten
3 Count the ones
Now there are 0 ones and 10 more ones.
That is 10 ones.
0 + 10 = 10
4 Write the number
So 60 is 5 tens and 10 ones.
60 = 5 tens 10 ones
Careful!
5 tens and 0 ones is only 50.
We must count the 10 new ones.
Careful: not 60 = 5 tens 0 ones ✗

5 tens is 50.
50 and 10 make 60.
Yes!
It works.
50 + 10 = 60
Let's look back.
First: show it with blocks.
Then: break a ten.
Then: count the ones.
Then: write the number.
Last: check.
