In geometry, a point is a fundamental concept that represents a specific location in space. It is often denoted by a dot and has no size, shape, or dimension. A point is considered to be infinitely small, and it is the building block for constructing geometric figures.

**Location:**A point represents a specific location in space.**No Size:**A point has no physical dimensions, such as length, width, or height.**Denotation:**It is usually denoted by a capital letter, such as A, B, C, etc.**Named Points:**Points can be named using letters, numbers, or symbols to distinguish them from one another.

If we have a two-dimensional coordinate system, a point can be represented by an ordered pair (x, y). For example, the point A(3, 5) would be located at 3 units to the right and 5 units upwards from the origin.

Number and Operations (NCTM)

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers.

Compute fluently and make reasonable estimates.

Use visual models, benchmarks, and equivalent forms to add and subtract commonly used fractions and decimals.

Algebra (NCTM)

Use mathematical models to represent and understand quantitative relationships.

Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.

Connections to the Grade 5 Focal Points (NCTM)

Algebra: Students use patterns, models, and relationships as contexts for writing and solving simple equations and inequalities. They create graphs of simple equations. They explore prime and composite numbers and discover concepts related to the addition and subtraction of fractions as they use factors and multiples, including applications of common factors and common multiples. They develop an understanding of the order of operations and use it for all operations.
