Describe 58 as a sun of tens and ones

10+10+10+10+10+1+1+1+1+1+1+1+1=58

First break it up so that will be 50 and 8.

Next ask yourself how many tens can go into 50. The answer is five so put 5 tens.

Then ask yourself how many ones can go into 8, the answer is 8. So put 8 ones and it will look like this;

10+10+10+10+10+1+1+1+1+1+1+1+1
