conceptual understanding
A deep understanding of mathematical ideas that goes beyond isolated facts and procedures to recognizing the connections between and usefulness of mathematical ideas in various contexts. For example, having a conceptual understanding of place value helps in understanding the various procedures involved when doing operations such as multiplying multi-digit or decimal numbers.
cone
A three-dimensional object with a circular base and a curved surface that tapers proportionally to an apex. See also three-dimensional object.
constant
A part of an algebraic expression that does not change. For example, in the expression x + y = k, k represents a constant and x and y are the variables. When k is equal to 1, 1 will remain the same, and the values of x and y can vary as long as they have a sum of 1. See also algebraic expression, variable.
constraint
A restriction placed on the parameters upon which a subroutine or program works or in a loop to define the scope of the problem.
coordinate system
A system used to specify location on a grid. The Cartesian plane is an example of a coordinate system. See also Cartesian plane.
correlation
A measure of the strength and the direction of the linear relationship between two variables. The correlation coefficient is the numerical measure of a correlation, and the closer the correlation coefficient is to 1 or −1, the stronger the linear relationship is between the two variables. A negative correlation indicates that as one variable increases in value, the other variable decreases in value.
cylinder
A three-dimensional object with two congruent, parallel faces and one curved surface. All cross-sections parallel to the base are identical. For example, a right circular cylinder (shown below) has two circular faces and a curved surface that is perpendicular to the base. See also three-dimensional object.
