What is a fraction?

Back

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

How do you add fractions with the same denominator?

Back

To add fractions with the same denominator, keep the denominator the same and add the numerators. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

What is the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width. For example, if a rectangle has a length of 5 units and a width of 3 units, its area is 5 x 3 = 15 square units.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 2 1/2 is a mixed number, which means 2 whole parts and 1/2 of another part.

Front

How do you convert an improper fraction to a mixed number?

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder becomes the new numerator over the original denominator. For example, 7/4 = 1 3/4.

Front

What is the perimeter of a shape?

Back

The perimeter is the total distance around a shape. To find the perimeter of a rectangle, add the lengths of all four sides. For example, for a rectangle with lengths 5 and 3, the perimeter is 2(5 + 3) = 16 units.

Front

What is a decimal?

Back

A decimal is a way to represent fractions using a point. For example, 0.5 is the decimal representation of 1/2.

Front

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, 1/2 x 3/4 = (1x3)/(2x4) = 3/8.

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line. Each mark represents a data point.

Front

What is the difference between a line segment and a line?

Back

A line segment has two endpoints and a fixed length, while a line extends infinitely in both directions without endpoints.
