hi

1. Start with this game:

 

Juego

2. Now it’s time to solve some problems, in your notebook, obviously:

problems

3. If we have some time, we can start with systems of equations with two unknowns.

 

 

 

 

 

0. Some mental calculations, like past friday:

1. I’ve made this applets to help you with your first attempts, solve 5 in your notebook and check the answers in the app:

2. Practice, practice, practice, with JC:

3. You can use the last ten minutes of this class to improve your short history of the solution of the second degree equation.

A trick to memorize the formula:

1. Now time to be creative: use Canva, Genially, Powerpoint or any other software of your preference to create a short history of the solution of the second degree equation. It can be in comic form, or text with ilustrations. Send it to me at the end of the class.
2. Time to translate (into english and into algebra):
