The Regrouping Algorithm

The regrouping algorithm is an essential technique that children learn when mastering addition with two or more digits. It enables them to add numbers efficiently by recognizing when a column’s sum exceeds nine and carrying the extra value to the next column. Here’s how kids can learn addition through the regrouping algorithm:

1. Understanding place value – it is crucial that children understand the concept of place value before introducing regrouping.
2. Identifying when regrouping is needed – this occurs when the sum of digits in a particular column is ten or greater.
3. Visual representation – use visual aids such as base-ten blocks to demonstrate regrouping.
4. Step-by-step process – introduce the regrouping algorithm to students using a poster such as this.
5. Practice – provide ample opportunities for students to practice.
6. Application and word problems – encourage students to apply the regrouping algorithm to solve word problems and real-life situations.
