  1. The Price is Right A 2nd Grade Math lesson involving the counting of money

  2. Over the weekend, I did some shopping and picked up a few things • How much money did I spend? • How much money did I have left?

  3. I started out with $5.00 • Lemons cost $0.67 • Pitcher cost $ 1.50 • Glasses cost $ 1.99

  4. What shall I do first? • In order for me to find out the total, I need to add the cost of the items I purchased. • $0.67 + $1.50 + $1.99 = ?

  5. Prior Knowledge - Regrouping • Remember, we add going from right to left. • Because these are 3-digit numbers we must think about place value • Ones, tens, hundreds going from right to left • When we add the ones column and find ourselves with a ten we carry it onto the tens column

  6. Let’s see how that works • 2 1 • $0.67 • + $1.50 • $1.99 • ------------ • $4.16 • The total came out to $4.16

  7. How much money did I have left? • In order for us to find out how much money I have left from the $5.00 I started with I need to take the total amount of $4.16 away from $5.00 • $5.00 - $4.16 = ?

  8. Here we go again… Regrouping • $5.00 • - $4.16 • ------------ • $0.84 • My change was $0.84

  9. Let’s try some problems on your own • Here are some receipts I have from different stores • I’ve blacked out the total and change received • I’d like you to find the total and the change received
