What is Regrouping in Addition?
Sometimes when we add numbers, we need to make a new group of ten!
When we add a one-digit number to a two-digit number and the ones column adds up to 10 or more, we "regroup" by making a new ten. We write down the extra ones and carry the new ten over to the tens column. It's like when you have 10 pennies and exchange them for 1 dime!
How to Add with Regrouping
1️⃣ Add the ones first. If you get 10 or more, make a new ten!
2️⃣ Write down the extra ones and carry the new ten to the tens column.
3️⃣ Add all the tens together, including any you carried over.

Parent Tips 🌟
- Use physical objects: Have your child use small items like buttons or coins to physically group and regroup when adding. Seeing the process helps understanding.
- Make it a game: Create flashcards with regrouping problems and turn it into a race against the clock or a points game.
- Relate to real life: Use examples like "If you have 28 cents and find 7 more, how much do you have?" to show practical applications.
