Writing inequalities to describe real-world situations
Description
Exercise Name: Writing inequalities to describe real-world situations
Math Missions: 6th grade (U.S.) Math Mission, Pre-algebra Math Mission, Mathematics I Math Mission Algebra I Math Mission, Mathematics II Math Mission
Types of Problems: 1

The Writing inequalities to describe real-world situations exercise appears under the 6th grade (U.S.) Math Mission, Pre-algebra Math Mission, Mathematics I Math Mission, Algebra I Math Mission and Mathematics II Math Mission. This exercise uses inequality symbols and variables to model actual situations.

## Types of Problems

There is one type of problem in this exercise:

1. Write an inequality: This problem provides a real-life situation that can be modeled with an inequality. The student is expected to write a inequality with a variable in the available space.

## Strategies

Translating word problems and confidence in the language of mathematics can assist with doing this exercise.

1. The inequalities never involve "equal to." In other words, it will either use < or >, there is no need for the <= or >=.
2. The number is in the problem but the direction of the inequality is determined by the question at the end.
3. There is no need for calculation on this exercise, reading and writing are all that is needed.

## Real-life Application(s)

1. For most people, in order to get their license they have to be at least 16. So, they can write this as an inequality. ${x}$ is the age of a person who wants to drive. In this case ${x}$ has to be greater than or equal to 16.
2. Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
