• Math in focus - Day 2: March 18, 2020

All Math in Focus students may follow the plans below.
Check with your math teacher regarding how she would like you to share your work.

**Pre-algebra students should visit Mrs. Bucher's website**

Overview:  Prime Numbers / Composite Numbers / Factors / Multiples

Estimated Time: Approximately 45 minutes

Explanation:   Today you will review prime and composite numbers, as well as complete activities using your knowledge of factors and multiples.

Things to know:

• The following definitions can be used while completing the tasks for today.
• prime number – a prime number has only two different factors, 1 and itself.
• composite number – a composite number has more than 2 different factors.
• factor – 12 can be divided exactly by 2. So, 2 is a factor of 12.
• multiple – a multiple of a number is the product of the number and any other whole number except zero.
• To review these concepts, you can check out Chapter 1 using Ed Your Friend in Learning
**Files needed for today's activities will be found in your Math Team.
Reach out to your math teacher if you cannot access the documents.

1. Continue recording the daily temperature on the chart you made yesterday.
2. Review Prime/Composite Numbers:
• Shuffle your set of number cards from yesterday.
• Flip over one card at a time. Determine if the number on the card is a prime number of a composite number.
• Shuffle your set of number cards again.
• This time flip over two cards creating a 2-digit number
• (ex: if you flip over a 4, then a 2, your number would be 42)
• Determine if the number on the card is a prime number or a composite number.
• Complete the PRIME/COMPOSITE T-Chart worksheet page.
• You may develop numbers on your own or use your number cards to create numbers to sort into each category.
3. Review Factors:
• Locate 5 numbers in your house. Each number must be a two digit number.  Fill in the Factors Chart for all 5 numbers. The Prime Factorization column is optional.
4. Review Multiples:
• Complete the Multiples worksheet by writing the next multiples of a chosen number.

Share today's work:

Remember, your work today is not graded, but I'd love to see what you've done. You can share your work with me through Teams, email (jsnyder@cbsd.org), Seesaw, or share your composition book with me when we return to school.
