Vocabulary 1
What do you call the top number of a fraction?
numerator
What do you call the bottom number of a fraction?
the denominator
Name 3 multiples of 4.
Any multiples of 4, for example: 4, 8, 12, 16, 20, 24
Name a fraction that is equivalent to 1/2.
Any equivalent fraction such as 2/4, 3/6, 4/8, 5/10, etc.
Explain the difference in size between 1/3 and 1/6.
If the numerators are the same, you can compare the denominators. The larger the denominator, the smaller the pieces, so 1/6 is smaller than 1/3.
These are the numbers you multiply to get a product.
factors
What is the area of a door that is 3 feet wide and 6 feet tall? How did you figure that out?
18 square feet. L X W = A
12/4 is equal to what whole number?
3
Name a fraction that is less than 1/2 and has a denominator of 6.
Either answer s correct: 1/6 or 2/6
Explain how you would compare these two fractions: 2/7 and 3/7.
If the denominators are the same, then all the pieces are the same size. You can then compare the numerators, which is how many there are of each piece. In this case, 3/7 is greater than 2/7.
If the directions say "Write an inequality to compare these numbers," what symbols do you use?
> or <
greater than or less than
What is the perimeter of a square poster that is 3 feet wide?
12 feet
What is the product of 6 and 7?
42
Is this inequality true? How do you know you are right? 3/4 > 4/8
Yes, 3/4 is greater than 4/8. I know because 4/8 is 1/2, and I know 3/4 is more than half. You could also use equivalent fractions to make common denominators: 4/8=2/4, so 3/4 would be greater.
What is a quadrilateral?
A polygon with 4 sides.
What do you call any quadrilateral with opposite sides that are parallel?
Parallelogram
Find the difference between 42 and 7.
35
How many 4ths are in 1 whole? 1/4, 2/4, 3/4, 4/4, or 5/4?
4/4
Is this true? 2/4 = 5/10 Explain how you know.
Yes. Both fractions are exactly 1/2.
What is a rhombus?
A polygon with 4 sides of equal length.
This is what you call two fractions that are equal, such as 2/8 and 1/4.
equivalent fractions
Is 8 the sum or the quotient of 2 and 6?
sum
Name 3 fractions with an 8 in the denominator that are more than 1/2 and less than 1.
5/8, 6/8, and 7/8
Put these fractions in order from least to greatest: 7/8, 1/6, 4/8
1/6, 4/8, 7/8
