Measure is the process of determining the size, length, weight, or quantity of something. It involves comparing an unknown quantity to a known standard in order to find the value of the unknown quantity.

There are different units of measurement used for different quantities. Some common units of measurement include:

- Length: meter (m), centimeter (cm), kilometer (km)
- Weight: gram (g), kilogram (kg), ton
- Volume: liter (L), milliliter (mL), cubic meter (m
^{3}) - Time: second (s), minute, hour, day

There are two main types of measurement: direct measurement and indirect measurement.

- Direct Measurement: This involves using a measuring tool, such as a ruler or scale, to directly measure the quantity.
- Indirect Measurement: This involves using mathematical formulas and proportions to calculate the quantity indirectly. For example, using the formula for the area of a rectangle to find the length or width.

Converting units involves changing a quantity from one unit of measurement to another. This is often done using conversion factors or unit conversion formulas.

- Practice using different measuring tools, such as rulers, protractors, and scales, to become familiar with direct measurement.
- Work on solving problems involving unit conversions to strengthen your understanding of converting units.
- Review mathematical formulas related to measurement, such as the formulas for area, volume, and perimeter.
- Use real-life examples to apply measurement concepts, such as measuring ingredients for a recipe or calculating distances on a map.

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.
