The quantity of matter present.

A standardized quantity used for a particular kind of measurement.

A three-dimensional object whose sides are all the same length.

A push or pull on a surface. In this module, a force is the weight of an object or a fluid.

A combination of a whole number with a fraction or decimal. Examples of _______ _______ are 3 7/16 and 1 1/4.

Fractions having different numerators and denominators but still having equal values, such as the fractions 1⁄2  and 2⁄4.

A fraction whose numerator is larger than its denominator. For example,  6∕3  is an _______ _______.

To reverse the order or position of numbers. In fractions, It means reversing the positions of the numerator and denominator, so 3⁄4  becomes 4⁄3. When dividing by fractions, one fraction is _______.

The length of a straight line that crosses from one side of a circle, through the center point, to a point on the opposite side. The _______ is the longest straight line that can be drawn inside a circle.

The amount of space contained in a two-dimensional object, such as a rectangle, circle, or square.

A closed curved line drawn at a constant distance around a central point. A _______ measures 360°.

A four-sided shape with four 90° angles. Opposite sides of a _______ are always parallel and the same length. Adjacent sides

A closed shape that has three sides and three angles.

(1) A special type of rectangle with four equal sides and four 90° angles. (2) The product of a number multiplied by itself. For example, 25 is the _______ of 5; 16 is the _______ of 4.

The distance around the outside of a closed shape, such as a rectangle, circle, square, or any irregular shape.

The distance around the curved line that forms the circle.

The distance from a circle’s center point to any point on the curved line, or half the width (diameter) of the circle.

A mathematical constant value approximately equal to 3.14 (or 22⁄7) used to determine the area and circumference of circles. It is sometimes symbolized by the Greek letter π.

The point at which two or more lines or curves come together.
