3️⃣ Checking Work: Always verify your answers
Let's Practice Together!
Problem Puzzle #1
Emma has 347 stickers. She gives 129 stickers to her friend. How many stickers does Emma have left?
Let's solve it step by step:
347 - 129 = ?
First, subtract the ones: 7 - 9 (we need to borrow!) → 17 - 9 = 8
Then subtract the tens: 3 - 2 = 1 (after borrowing)
Finally subtract the hundreds: 2 - 1 = 1
Answer: 218 stickers left!
Real-World Challenge
A school library has 1,258 books. 489 books are checked out. Then, the library gets 325 new books. How many books are in the library now?
This is a two-step problem:
Step 1: 1,258 - 489 = 769 books (after checkouts)
Step 2: 769 + 325 = 1,094 books total now
Answer: 1,094 books in the library!
