Dividing fractions

With the following video you can remember how to divide fractions:

Just remember: KEEP, CHANGE AND FLIP!

Order of operations

Multiplying and dividing integers

Remember: "Quotient product signs, same rule apply"

ADDING AND SUBTRACTING INTEGERS

I'm sure this video will help you to remember how to add integers, and I hope you like it...

¡EMPIEZA UN NUEVO CURSO!

Por si todavía no os habeis dado cuenta, os aviso de que ya ha comenzado el curso 2017/2018. Efectivamente, siento deciros que las vacaciones han terminado, lo que quiere decir que ha llegado el momento de volver a estudiar y trabajar. Y cuanto antes empeceis, mucho mejor para vosotros.

Así que, después de hacer la prueba de evaluación inicial, empezamos la primera unidad del curso, "Integers". Ya están disponibles las fichas de trabajo de la unidad en este blog (sí, aquí a la derecha, donde pone "worksheets").

Tan sólo desearos un buen curso y, sobre todo...

The Pythagorean theorem

This morning we did a revision of the Pythagorean theorem watching this video from Khan Academy:

Create your own tesellation

As a final task of our integrated unit "Geometry in the Alhambra" you have to create your own tesellation using the application Geogebra. Remember you can start your construction with a square, as I explained in class, or with a equilateral triangle, as you can see in this video:

Visiting the Alhambra

Last week we were working on a new integrated unit about the Alhambra.

First we watched this video in class:

 Remember the tasks and activities we did:

TASK 1: Investiga un poco sobre la relación entre las matemáticas y la Alhambra, y busca la respuesta a esta pregunta:

1) ¿Por qué los árabes usaban tanto la geometría para las decoraciones de sus palacios?

2) ¿Cuál es el número áureo o de oro? ¿Por qué es tan importante?

3) ¿Qué es un rectángulo áureo? ¿En qué lugar de la Alhambra podemos encontrar rectángulos áureos?

Task 2: What is a tessellation?

Activity 1: Cover the space on the following rectangle by drawing polygons. Do it your own way. The only rule is to not leave gaps between the polygons.

Activity 2: Is it possible to cover a surface with other regular polygons?

Activity 3: Geometric transformations: Translation, Rotation and Reflection.

Task 3: What tessellations can we find in the Alhambra?
