|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:
- 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.
Translating word problems and confidence in the language of mathematics can assist with doing this exercise.
- The inequalities never involve "equal to." In other words, it will either use < or >, there is no need for the <= or >=.
- The number is in the problem but the direction of the inequality is determined by the question at the end.
- There is no need for calculation on this exercise, reading and writing are all that is needed.
- For most people, in order to get their license they have to be at least 16. So, they can write this as an inequality. is the age of a person who wants to drive. In this case has to be greater than or equal to 16.
- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
