Constants

In mathematics, a constant is a value that does not change. It is a fixed and specific number that remains the same in all contexts. Constants are used in equations, formulas, and expressions to represent known values.

There are different types of constants, such as:

Numeric Constants: These are specific numbers, such as 3, 5, or 10.
Mathematical Constants: These are special numbers with significance in mathematics, such as π (pi) or e (Euler's number).
Physical Constants: These are values that represent physical quantities, such as the speed of light or the gravitational constant.

Constants are often denoted by specific symbols or letters, and their values are defined and fixed. In algebraic expressions, constants are often combined with variables and operators to form mathematical equations.

For example, in the equation y = 2x + 5, the number 5 is a constant because it does not change as the value of x varies. Similarly, in the formula for the area of a circle, A = πr², the value of π is a constant representing the ratio of the circumference to the diameter of a circle.

Understanding constants is important in various areas of mathematics and science, as they provide known and fixed values that are essential for solving problems and making calculations.

Overall, constants play a crucial role in mathematical expressions and equations, serving as unchanging values that contribute to the understanding and application of mathematical concepts.

Identify Quadrilaterals

The resources above cover the following skills:

Geometry (NCTM)

Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships.

Identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes.

Classify two- and three-dimensional shapes according to their properties and develop definitions of classes of shapes such as triangles and pyramids.

Use visualization, spatial reasoning, and geometric modeling to solve problems.

Recognize geometric ideas and relationships and apply them to other disciplines and to problems that arise in the classroom or in everyday life.

Grade 3 Curriculum Focal Points (NCTM)

Geometry: Describing and analyzing properties of two-dimensional shapes

Students describe, analyze, compare, and classify two-dimensional shapes by their sides and angles and connect these attributes to definitions of shapes. Students investigate, describe, and reason about decomposing, combining, and transforming polygons to make other polygons. Through building, drawing, and analyzing two-dimensional shapes, students understand attributes and properties of two-dimensional space and the use of those attributes and properties in solving problems, including applications involving congruence and symmetry.
