Area is a measure of the size of a surface or a two-dimensional shape. It is the amount of space inside a shape, and is measured in square units. The most common units used to measure area are square inches, square feet, square meters, and square centimeters.

The formula for calculating the area of different shapes are as follows:

- For a square or rectangle, the area is calculated using the formula:
**Area = length x width**. - For a triangle, the area is calculated using the formula:
**Area = (base x height) / 2**. - For a circle, the area is calculated using the formula:
**Area = π x (radius x radius)**, where π (pi) is a constant approximately equal to 3.14159.

To practice calculating area, you can use the following study guide:

- Start by understanding the concept of area and the formula for calculating area for different shapes.
- Practice calculating the area of squares, rectangles, triangles, and circles using the respective formulas.
- Use real-life examples to apply the concept of area, such as calculating the area of a room, a piece of land, or a circular swimming pool.
- Work on word problems that involve finding the area of different shapes, as this will help you in applying the concept to real-world scenarios.
- Use online resources and math worksheets to further practice and reinforce your understanding of area.

Grade 6 Curriculum Focal Points (NCTM)

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
