Terminando con las rectas

Posted by ricardogm on 25th March 2018

Muy buenas

Terminamos el trimestre y también el tema de rectas.

1. Primero haremos una construcción con Geogebra para visualizar los pasos a seguir para hallar la distancia de un punto a una recta. Lo enviáis, por supuesto.

Y ahora un repaso del tema de rectas. Los hacéis en la libreta y corregís en la página:

Si no funciona, aquí está en pdf:

A la vuelta trabajaremos con geogebra, en un primer acercamiento a los lugares geométricos.

Functions I

Posted by ricardogm on 22nd March 2018

Hi

We are starting with functions today:

1. Read this page and send me an email with the most important things you see there. You should find what a function is, what rules it has and what domain means, at least.

2. Open this Geogebra applets with a simple example of a function.

Now, play with them and try to answer these questions:

a) What does f(3) mean? How much is it? How can you calculate that?

b) Are there more than one value of a with the same value of f(a)? Is that possible in a function?

Send me the answers.

3. Now we are going to create something similar. Pay attention and send me the file.

4. Read pages 40 and 41 of this book . They show you how to calculate the domain of a function.

5. With this information, solve these exercises:

domain.pdf

6. More exercises.

You can find the same exercises with solutions in this link.

Parallels, perpendiculars, cockroaches…

Posted by ricardogm on 8th March 2018

 

Hi

1. In order to better fight cockroaches, we are going to prepare a Geogebra file, and I hope that  this way you are going to visualize the slope and the y-intercept of a line really fast. It’s going to be something like that:

2. Now, an easier thing about parallels and perpendicular lines.

Send them to me, and now you can kill them all:

Algebra vs cockroaches.

Show me your level number. The higher you get, the better.

Flatland 2

Posted by ricardogm on 1st March 2018

Tasks to do in the computers room:

1. Create a geogebra thing about lines. Pay attention. Something like that:

2. Create a mini flatland with Geogebra, with animated characters. Pay attention. This is an example:

3. Play this game.
