I will be able to divide numbers using the standard algorithm.

MANY DIFFERENT WAYS TO DIVIDE

What are possible methods for dividing (discuss with partner).

RECOGNIZING A DIVISION PROBLEM

𝒅𝒊𝒗𝒊𝒅𝒆𝒏𝒅÷𝒅𝒊𝒗𝒊𝒔𝒐𝒓 𝒅𝒊𝒗𝒊𝒔𝒐𝒓 √𝒅𝒊𝒗𝒊𝒅𝒆𝒏𝒅The answer is a quotient.

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).

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. Divide2. Multiply3. Subtract 4. Bring down

WHY USE THE STANDARD ALGORITHM?

The most efficient Works best for decimals

SUMMARIZE
