Prime & Composite Numbers
Prime numbers are positive integers (numbers) that have only two positive integer factors: 1 and themselves. (They can only be divided equally by 1 and themselves)For example, the first six prime numbers are 2, 3, 5, 7, 11, and 13.
Composite numbers are positive integers (numbers) that have more than two positive integer factors. They can be written as the product of two or more prime numbers. For example, 4 is a composite number because it can be written as 2 x 2. 6 is also a composite number because it can be written as 2 x 3.
It's important to note that 1 is not considered a prime number because it has only one positive integer factor: 1 itself.

Task 6: For Fun. Click on the picture below.
Task 7: Partner Work. Collect a sheet from the teacher. Find the Prime Numbers to complete the maze and help the dog reach the bone. You may use a calculator if needed.
Task 8
|
Find the station with these numbers 1-100 in a box. Pull out 10 random numbers. Decide if they are Prime or Composite If they are composite, write down all of the factors (numbers that can be multiplied to make the whole number) For e.g.- If you get the number 12 in your book you would write 1. 12: 1,2,3,4,6,12 (Composite) If you got 7 you would write 2. 7: Prime |

TASK 9
Book Work- Note Taking
1. Write the title, 'Prime and Composite Numbers; Factors and Multiples' at the top of your Math book.
2. Use notes on your laptop or a piece of paper to draft your definitions and examples.
3. Get the template from Mrs. Russell. Cut it out and fold. Write your information on the sheet and glue it into your book.
