In mathematics, the symbol "=" is used to indicate that two quantities or expressions are the same. When we say that one quantity is equal to another, we are essentially stating that they have the same value.

Understanding the concept of equality is fundamental in mathematics. It is important to grasp the notion that when two things are equal, they are interchangeable and can be used in place of each other.

Here are some examples of the use of the equal to sign:

- 3 + 4 = 7 (3 plus 4 is equal to 7)
- 12 - 5 = 7 (12 minus 5 is equal to 7)
- 2 * 3 = 6 (2 times 3 is equal to 6)
- 10 ÷ 2 = 5 (10 divided by 2 is equal to 5)

To understand the concept of "equal to" better, here are some key points to remember:

**Definition:**The symbol "=" is used to show that two quantities are the same.**Interchangeability:**When two things are equal, they can be used interchangeably.**Examples:**Practice writing and solving equations using the equal to sign.**Properties:**Learn about the properties of equality, such as the reflexive, symmetric, and transitive properties.

By understanding the concept of "equal to" and practicing its application, you will develop a strong foundation in algebra and other areas of mathematics.

Use geometric models to represent and explain numerical and algebraic relationships.

Measurement (NCTM)

Apply appropriate techniques, tools, and formulas to determine measurements.

Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.

Develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes.

Connections to the Grade 7 Focal Points (NCTM)

Measurement and Geometry: Students connect their work on proportionality with their work on area and volume by investigating similar objects. They understand that if a scale factor describes how corresponding lengths in two similar objects are related, then the square of the scale factor describes how corresponding areas are related, and the cube of the scale factor describes how corresponding volumes are related. Students apply their work on proportionality to measurement in different contexts, including converting among different units of measurement to solve problems involving rates such as motion at a constant speed. They also apply proportionality when they work with the circumference, radius, and diameter of a circle; when they find the area of a sector of a circle; and when they make scale drawings.
