You can use a T chart to identify factors. Of a whole number that is a composite number. Remember to stop when there is a repeated number.

Once you have the T chart done start listing the factors all in a row. From least to greatest.

1,2,3,4,6,8,12,24

Is 24 Composite or Prime?

Is 13 Composite or Prime?

C! (Composite)

P! (Prime)

Pick a number that you like from above and explain why it is Prime or Composite.

I think that 24 is composite because all composite numbers have more than 2 factors.

Is 82 divisible by 10?

24 is divisible by 3 because 2+4=6 and 3*2=6. So it is divisible by 3.

36 is divisible by 6 because 36 is divisible by 2 because 18*2=36. And 36 is divisible by 3 because 3+6=9 and 9/3=3.

82 is divisible by 2 because 4*2=8 and 2*1=2. So 82/2=41.
