4th Grade Math Vocabulary Quiz

An expression in mathematics refers to combinations of numbers, symbols, and operators that represent a mathematical relationship or formula. It is used to perform calculations and solve mathematical problems.

An equation is a mathematical statement that asserts the equality of two expressions, often containing variables.

Division is the process of separating a quantity into equal parts. It is the opposite of multiplication and involves sharing or separating a number into smaller, equal groups.

A decimal number is defined as having a decimal point that separates the whole number part from the fractional part. It does not necessarily have to be divisible by 10, can have fractions, and can be any value, not limited to being greater than 100.

The correct answer describes 'remainder' in the context of division, where it represents the amount that is left over after dividing a number into equal groups.

The term 'Tenth' specifically refers to one out of 10 equal parts. It is a fractional value representing 1/10.

A hundredth represents one part out of a total of 100 equal parts, making it a fraction with the denominator of 100.

A mixed number is made up of a whole number and a proper fraction. It is commonly written in the form of a whole number followed by a fraction, such as 2 1/2.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator, indicating a value greater than 1. The other options describe different types of fractions or relationships between the numerator and denominator that do not fit the definition of an improper fraction.

An acute angle is defined as an angle that is smaller than a right angle, or less than 90 degrees.

A right angle specifically refers to an angle that is formed by two lines perpendicular to each other, creating a 90-degree angle.

An obtuse angle is between 90 and 180 degrees, making it greater than a right angle (90 degrees) but less than a straight angle (180 degrees).

Parallel lines are always equidistant from each other and will never cross paths.

Perpendicular lines or segments intersect at right angles, forming a 90-degree angle.

Translation in geometry specifically refers to the movement of a shape without any rotation or flipping involved.

In geometry, a reflection is a transformation that creates a mirror image of the original shape by flipping it over a line. It does not involve rotating, changing the size, or stretching the shape in any way.

Rotation specifically refers to the act of turning a shape around a central point, not simply moving from one place to another, reflecting over a line, or changing the size of a shape.
