=== '''Subtraction without regrouping''' ===
In the tens place from 2 tens 1 tens was already broken into ten units therefore only 1 ten is remaining. Now we will find the difference of the tens place value that is 1-1=0. The facilitator tells so the difference of 26-19 is 7. this was also explained by using standard algorithm of subtraction. Few sums were solved with the interaction of the students. And few sums were given to students for the practice.
