3rd grade addition without regrouping game - In Addition, there are instances that numbers have 'carry' on top of them, we call it Addition with regrouping. However, if they do not have 'carry' on top of them, we call it Addition without regrouping. If we are adding two-digit numbers, we should always place them according to their place values. After we placed them up according to their place values, we can now proceed in adding these numbers. For example, we have the two-digit numbers 13 and 24. First, we line them up according to their place values which are the ones and tens. Make sure that the first addends are on top of the other in order to make a column of numbers. The numbers 3 and 4 are in ones while the numbers 1 and 2 are in tens. After we lined them up, we can now proceed in adding these two-digit numbers. In adding two or more digit numbers, always remember to start from right to left. Let us now add 3 and 4 that is equal to 7 and 1 and 2 that is equal to 3, these numbers are in ones and tens place values respectively. These numbers do not have a 'carry' so it is an addition without regrouping. By adding these two-digit numbers, we obtained the answers: 3 from the tens place value and 7 from the ones place value. Together, the sum of 13 and 24 is 37.
