2. PRE-ALGEBRA Tuesday, August 12

3. TODAY’S LEARNING TARGET I will be able to divide numbers using the standard algorithm.

4. MANY DIFFERENT WAYS TO DIVIDE What are possible methods for dividing (discuss with partner).

5. RECOGNIZING A DIVISION PROBLEM The answer is a quotient.

6. STEPS FOR THE STANDARD DIVISION ALGORITHM  Keep everything lined up in columns (preserve place value)  Be careful with calculations …there are so many ways to make a mistake  Use estimation strategies to test the reasonableness of your answer  Double check your work (if you are taking a test you will need to divide twice, at home check your work with a calculator).

7. PRACTICE WITH 2 DIGIT DIVISORS CARRYING OUT TO THE HUNDREDTHS PLACE  Write out our division problem putting one number in each square on your graph paper (holding place value)  You can multiply 27 times 1 – 9 to help you with the division problem. Work with your partner to complete the multiplication  Follow the steps using “dad, mom, sister, brother” 1. Divide 2. Multiply 3. Subtract 4. Bring down

8. WHY USE THE STANDARD ALGORITHM?  The most efficient  Works best for decimals

9. SUMMARIZE  What are important things to remember when dividing numbers?

10. RATE YOUR UNDERSTANDING I will be able to divide numbers using the standard algorithm
