What Does "Without Regrouping" Mean?
Subtracting without regrouping is like taking away cookies from two jars when you have enough in each jar!
When we subtract two-digit numbers without regrouping, it means we don't need to borrow from the tens place because the top number is bigger in each place value.
How to Subtract Two-Digit Numbers Without Regrouping
1️⃣ Line up the numbers by their place values (tens and ones)
2️⃣ Subtract the ones place first (right column)
3️⃣ Subtract the tens place next (left column)

Parent Tips 🌟
- Use physical objects: Have your child use blocks or buttons to represent the numbers and physically take away the subtracted amount.
- Make it a game: Create subtraction flashcards and time how many they can solve correctly in one minute.
- Relate to real life: Ask subtraction questions like "If you have 45 marbles and give 23 to a friend, how many do you have left?"
