Length is a measurement that refers to how long an object is from one end to the other. It is one of the fundamental measurements in mathematics and is usually measured in units such as meters, centimeters, inches, feet, etc.

Here are some commonly used units of length:

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

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

1 meter = 100 centimeters

1 meter = 39.37 inches

1 foot = 12 inches

Length can be measured using instruments such as rulers, tape measures, or meter sticks. When measuring length, it is important to ensure that the starting point of the measurement is accurate and that the measurement is taken in a straight line.

1. Convert 2 meters to centimeters.

Answer: 2 meters = 200 centimeters

2. Convert 36 inches to feet.

Answer: 36 inches = 3 feet

3. Measure the length of the following objects using a ruler and record your measurements in both inches and centimeters:

- A pen
- A book
- Your desk

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.
