Maths Unit 3

Unit 3 was all about prime numbers, multiples, factors, composite numbers, sums, and open number sentences.

I learned that all even number cannot be prime except 2. I also learned that all prime numbers only have two factors and all composite numbers have three or more factors.          My favorite thing we did is when we had to finish the hole chart of factors and we have to write all the factors of all the number up to 100 it had.

I think I should practice more about adding a lot of numbers together and subtracting numbers. I was surprised when I came in class after I was sick and I did not know any thing about prime or composite then I only watched one video and I knew everything about prime and composite.
