Teaching addition is a critical component of early math education. Addition with regrouping, also known as carrying, is a method used to add two or more numbers when the sum of any column is greater than 9.

For example : Add 8 + 6 or 9 + 7, where regrouping is required. Regrouping involves carrying over the extra value to the next column.

Addition with regrouping is related to real-life situations to demonstrate its relevance, such as adding money amounts or calculating the total cost by buying items at a store. This helps kids understand that addition is used in everyday situations.

Before taking on the topic of addition with regrouping, kids should be well versed in the knowledge of place value, focusing on the ones, tens, and hundreds. Kids should also have good hold over addition without regrouping.

When adding two-digit or three-digit numbers, each place value column should be added separately, starting from the rightmost column (ones) and moving to the left (tens, hundreds, etc.).

## Step-by-step process for adding with regrouping :

Addition with regrouping is done when addition is performed by the column method (addends are split according to place value and arranged in columns, and digits in each column are added separately).

Regrouping is used when the sum or total of any column comes to be in 2 digits. ( more than 9 ).

When the sum of the digits of any column comes in 2 digits, then tens digit is carried over to the next column, like if the sum is 14, then 4 is written under that column and 1 is carried forward to the next column on the left.

For example :

Kids can be given more practise through several examples of addition problems with regrouping with simple two-digit numbers, gradually increasing the complexity.

Teaching addition with regrouping by activities :

Learning the addition can be made enjoyable by incorporating interactive games and activities.

This is a fun way to practise addition with regrouping. In this activity, equation makers using rings can be made (as shown in the picture below) and given to kids. This activity can be performed in the following steps :

• Kids can be said to twist the rings and set the equation.
• One by one, each kid is asked the sum of the set equation.
