Muy buenas

Vamos a empezar con un poco de cálculo mental, ayudará a lo que sigue:

1. https://chemarias.com/cm/tabla/index.html. Haced tres intentos y enviad captura de pantalla del mejor resultado. PISTA: se gana velocidad con el teclado numérico.

 

2. Vamos a trabajar con Geogebra varios casos de la ecuación explícita (con y despejada) de la recta, y=mx+n.

a) Rectas horizontales.

b) Rectas verticales.

c) Rectas en la forma y=mx+n, donde m es la pendiente y n la ordenada (la y) en el origen (x=0),

 

3. Ahora ya podemos jugar a esto:

Hoy vamos a aprovechar Geogebra para explicar cómo se construye una recta y el concepto de pendiente, con estas construcciones:

  1. La básica, que se corresponde con la definición y la ecuación vectorial.
  2. Una sobre la pendiente.
  3. Una última sobre la fórmula punto-pendiente.

Y después empezamos repaso para el examen, con estos ejercicios. Hacedlos en la libreta y comprobad luego en el liveworksheet, mandad captura del resultado.

40 Math Memes That Are Funny Even If You S**k At Math

Hi, today we start as usual, but only with this one:

1. https://chemarias.com/cm/tabla/index.html. Three attempts and one screenshot.

 

Today we start a new unit, proporcionality, in which the most important concepts are ratios and proportions. Here you have an article about them:

Ratio and Proportion in Math

But we are going to use this clasroom to learn a bit about that with the help of  Javier Cayetano:

Next one, the rule of three. First an explanation:

Rule of Three is a Mathematical Rule that allows you to solve problems based on proportions

And now, some exercises:

Percentages are an special case of proporcionality, quite common. Some exercises:

Muy buenas

Vamos a empezar el tema de vectores (y rectas) trabajando con Geogebra, que para esto viene estupendo. Las tareas que haremos serán:

  1. Una construcción básica en la que podamos visualizar qué es un vector y alguna de sus características, como el módulo.
  2. Otra sobre suma y resta de vectores.
  3. Una tercera sobre combinaciones lineales de vectores.
  4. La última, en la que intentaremos animar un personaje utilizando deslizadores y combinaciones lineales de vectores.

Para terminar, os cuelgo una lista completa de videos sobre el tema:

Hi, as usual, mental calculations to warm up. Try to improve over the previous sessions:

1. https://chemarias.com/cm/tabla/index.html. Three attempts and one screenshot.

2. https://mathster.com/10secondsmaths/ . Use all the operations. Five minutes and one screenshot.

 

2. Some worksheets to solve, you can do the calculations in your notebook, and answer the question in the worksheet. Take a screenshot of your results:
