Thales

Thales was the mathematician who measured the Pyramids with similarity, and today we are going to create a Geogebra thing with his theorem.
First, some mental calculations:

And a video:
Now pay attention to the Geogebra instructions.
Similarity

- Hi, start with some calculations training (10 minutes and screenshot):

2. Time to play with Geogebra, pay attention and don’t forget to send me screenshots.

Linear functions

Hi
We are going to use Geogebra but, first, some game practice:
(we need a little bit of help to play. The game uses linear functions, -rectas- in the form y=mx+n.)
a) Horizontal lines, in the form y=a number
b) Vertical lines, in the form x=a number
c) Full lines in the form y=mx+n, where m=slope –pendiente o inclinación– and m is y-intercept –la ordenada (la y) en el origen (x=0)-,
1. Now we can play this game:
2. Some geogebra work, pay attention. (linear functions and quadratic). Send screenshots
3. A worksheet

Animating with functions 2

Hi
We are going to use Geogebra to animate things but, first, some game practice:
(we need a little bit of help to play. The game uses linear functions, -rectas- in the form y=mx+n.)
a) Horizontal lines, in the form y=a number
b) Vertical lines, in the form x=a number
c) Full lines in the form y=mx+n, where m=slope –pendiente o inclinación– and m is y-intercept –la ordenada (la y) en el origen (x=0)-,
1. Now we can play this game:
2. Another game:

2. Animation time. Choose a character (best with transparent background), I’m going with my faithful Homer:

a) First we are creating an scene with some tricks to change the functions and show/hide things.
b) Then we are going to insert the image to move aorund, and learn how to do properly.
c) Then we are going to be creative.
