In mathematics, "equal to" is a fundamental concept that represents the relationship between two quantities that have the same value. The symbol used to denote equality is the equals sign (=). When two quantities are equal, they have the same value and can be replaced by one another in a mathematical expression or equation.

**Equality:**Two quantities are equal if they have the same value. The equals sign (=) is used to show that two expressions are equal.**Equations:**An equation is a mathematical statement that shows the equality of two expressions. It consists of an equals sign between two expressions, known as the left-hand side (LHS) and the right-hand side (RHS).**Equivalent:**When two expressions or equations have the same value, they are considered equivalent. This means that they can be interchanged without changing the truth of a statement.

Here are some examples to illustrate the concept of "equal to":

- 3 + 5 = 8
- x + 7 = 15
- 2y = 10

When working with the concept of "equal to", it's important to understand the following key points:

- Recognizing the equals sign (=) and understanding its meaning.
- Understanding that the quantities on either side of the equals sign have the same value.
- Practicing solving equations by performing operations to maintain equality.
- Identifying equivalent expressions and equations.

By mastering the concept of "equal to", you will be able to solve equations, manipulate expressions, and understand the fundamental principles of algebra and arithmetic.

Remember to practice solving equations and identifying equivalent expressions to reinforce your understanding of "equal to".

Geometry (NCTM)

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

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 6 Focal Points (NCTM)

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
