Hello all! As I start my unit on fractions, I instructed the students that there is a large amount of vocab attached. It is imperative that they learn to speak "fractions", in order to do fractions. One of the only ways I know to learn a new language, is to practice, practice and practice. Starting tomorrow, there will be a math quiz about every 3-5 days reviewing all these new terms. Of course we will be reviewing and speaking fractions everyday, but it is important that you review at home too. Here are this weeks terms and definitions:
1. What is a fraction?
a. a broken number - think of a graham cracker (a whole) being dropped and broken into pieces (fraction)
b. a number divided by another number 1/2
c. a fraction is not a whole number
2. Parts of a fraction:
3 numerator part or pieces of the number top number
10 denominator whole bottom number
3. What is a factor?
Factors are the numbers you multiply by to get another number.
example: Factors of 10
1 x 10=10 2 x 5=10 or 10: 1, 2, 5, 10
10 has 4 factors
4. What is a prime number?
A prime number only has 2 factors
example: Factors of 3
1 x 3=3 or 3: 1,3
3 has 2 factors making it a prime number
5. What is a composite number?
A composite number has 3 or more factors
example: Factors of 8
1 x 8=8 2 x 4=8 or 8: 1, 2, 4, 8
8 has 4 factors
