Mass

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).

Understanding Mass

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.

Calculating Mass

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

Study Guide

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.

Connections to the Grade 5 Focal Points (NCTM)

Algebra: Students use patterns, models, and relationships as contexts for writing and solving simple equations and inequalities. They create graphs of simple equations. They explore prime and composite numbers and discover concepts related to the addition and subtraction of fractions as they use factors and multiples, including applications of common factors and common multiples. They develop an understanding of the order of operations and use it for all operations.
