Length is a measurement of how long an object is. It is one of the fundamental properties of an object and is commonly measured in units such as meters, centimeters, inches, feet, etc.

There are various units of length used for measurement. Some common units include:

- Meter (m)
- Centimeter (cm)
- Inch (in)
- Foot (ft)
- Yard (yd)

It is important to be able to convert between different units of length. Here are some conversion factors:

- 1 meter = 100 centimeters
- 1 foot = 12 inches
- 1 yard = 3 feet

Length can be measured using various tools such as rulers, tape measures, meter sticks, and yardsticks. It is important to use the appropriate unit of measurement for the object being measured.

1. Convert 2.5 meters to centimeters.

**Answer:** 2.5 meters = 250 centimeters

2. How many inches are in 3 feet?

**Answer:** 3 feet = 36 inches

3. If a rope is 5 yards long, how many feet is it?

**Answer:** 5 yards = 15 feet

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.
