This is a Clilstore unit. You can .
In this unit, we will learn to solve first degree equations. We are going to do it in three steps, increasing the dificulty in each step.
For this aim you must see these three videos . As you will see, the dificulty increases in each one.
First of all, we are going to see how to solve very simple equations, with only additions and subtractions.
In the second video I show you simple equations with multiplications and divisions.
Finally, in the next video we will combine the four basics operations, and we will have to remember the hierarchy of basic operations.
After all, you have to practice hard to better support this concepts.
In the next links you will find several exercises for this purpose.
