Commutative and Associative Properties

Watch the video as many times as you need.  Then,WSQ in your notes.  (W=work,do any problems given throughout the video, S=summary, answer the summary questions below in your notes; Q=question(s), list any questions you have about the content of the video.)


Summary:
1. Define Commutative Property.
2. Define Associative Property.
3. How do you use these properties to do mental math?

Using the Division Algorithm

Watch this video as many times as you need. WSQ in your notebooks.  

W = Work out any problems assigned during the video in your notes.

S = Summarize the video.  Answer the summary questions below.

Q = Question you have or a question someone else might have about the information in the video. This can also be a question that sparks discussion or causes other to think about the topic more deeply.

Summary:

1. Write a mnemonic device (like PEMDAS or Please Excuse My Dear Aunt Sally is used to help remember the Order of Operations) for the steps in the division algorithm.

2. What are the steps of the division algorithm? 

Modeling Division with Area Models

Watch this video as many times as you need to and complete the companion worksheet.

Estimation with Whole Numbers (Rounding)

Watch this video as many times as you need. WSQ in your notebooks.  

W = Work out any problems assigned during the video in your notes.

S = Summarize the video.  Answer the summary questions below.

Q = Question you have or a question someone else might have about the information in the video. This can also be a question that sparks discussion or causes other to think about the topic more deeply.

Summary:

1. Which digit in a given number determines if you round up or down?
2. When do you round up?
3. When do you round down?
4. What do you do with all digits that come after the place column you are rounding to?

Prime Factorization

Watch this video as many times as you need. WSQ in your notebooks.  

W = Work out any problems assigned during the video in your notes.

S = Summarize the video.  Answer the summary questions below.

Q = Question you have or a question someone else might have about the information in the video. This can also be a question that sparks discussion or causes other to think about the topic more deeply.

Summary:
1. What are prime numbers?
2. List the steps for finding the Prime Factorization of a number.
3. How can you simplify the Prime Factorization of a number once you have listed all of the prime factors?

4. How are factoring and evaluating related?

Sieve of Eratosthenes

Watch this video as many times as you need to, then fill in the second side of the sieve.

Don't forget to list at least 3 observations you made throughout the lesson on the bottom of the back side.
