In math, mass refers to the amount of matter in an object. It is often measured in units such as grams (g) and kilograms (kg).

To understand mass, it's important to know the following concepts:

**Measurement Units:**Mass is typically measured in grams and kilograms. 1 kilogram (kg) is equal to 1000 grams (g).**Comparing Mass:**When comparing the mass of two objects, you can use terms like "heavier than," "lighter than," or "equal to."**Using Scales:**Mass can be measured using a scale. A balance scale is commonly used to compare the mass of different objects.

To calculate the mass of an object, you can use the following formula:

Mass = Weight / Acceleration due to gravity

For example, if the weight of an object is 50 N (Newtons) and the acceleration due to gravity is 9.8 m/s², then the mass would be:

Mass = 50 N / 9.8 m/s² ≈ 5.1 kg

Here are some key points to remember when studying mass:

- Mass is the amount of matter in an object.
- It is measured in grams (g) and kilograms (kg).
- 1 kilogram (kg) = 1000 grams (g).
- Objects can be compared based on their mass using terms like "heavier than," "lighter than," or "equal to."
- Mass can be calculated using the formula: Mass = Weight / Acceleration due to gravity.

Understanding mass is essential for various math problems and real-life applications, such as measuring ingredients in cooking or determining the weight of objects.

Measurement (NCTM)

Understand measurable attributes of objects and the units, systems, and processes of measurement.

Understand such attributes as length, area, weight, volume, and size of angle and select the appropriate type of unit for measuring each attribute.

Understand the need for measuring with standard units and become familiar with standard units in the customary and metric systems.

Understand that measurements are approximations and how differences in units affect precision.

Apply appropriate techniques, tools, and formulas to determine measurements.

Select and apply appropriate standard units and tools to measure length, area, volume, weight, time, temperature, and the size of angles.

Grade 5 Curriculum Focal Points (NCTM)

Geometry and Measurement and Algebra: Describing three-dimensional shapes and analyzing their properties, including volume and surface area

Students relate two-dimensional shapes to three-dimensional shapes and analyze properties of polyhedral solids, describing them by the number of edges, faces, or vertices as well as the types of faces. Students recognize volume as an attribute of three-dimensional space. They understand that they can quantify volume by finding the total number of same-sized units of volume that they need to fill the space without gaps or overlaps. They understand that a cube that is 1 unit on an edge is the standard unit for measuring volume. They select appropriate units, strategies, and tools for solving problems that involve estimating or measuring volume. They decompose three-dimensional shapes and find surface areas and volumes of prisms. As they work with surface area, they find and justify relationships among the formulas for the areas of different polygons. They measure necessary attributes of shapes to use area formulas to solve problems.
