TOURISM IN AVILÉS

These are the results of your investigation. You can easily see the two or three countries that dominate the chart.  They are probably the countries that bring Avilés most of its tourism. Do you agree?

Hi, nenos and nenas

Today we are going to improve our spreadsheet skills, but before that…

1. Go to this web and read all the items and answer all the tests. How am I going to correct you? Pay attention. Copy one test and paste it in a word document, and answer the questions in the document. Save it and send it to matesytic@gmail.com. Then do the same with another test, and so on. You have 40 minutes for that task

Hi

Do you know what a spreadsheet is? We call it “hoja de cálculo” in spanish, and one of the most popular is Excel. We are going to repeat some of the exercises we did in class with Excel, so pay attention to your teacher and write down in your notebook all the instructions.

## More 3D shapes, in Gauss project site

Posted by ricardogm on 24th March 2011

Hi

Today we are going to visit the Gauss project site. It has been created by two teachers from Asturias. In fact, one of them is from Avilés and the other one from Pravia. Tasks for today:

1. Pay attention to your teacher. He is going to give you an overview of the site and some intructions. To make it easier, turn off your screen.
2. Visit the pages that start with ” desarrollo de…” Work out two or three questions from each page and write the answers in a word document. Save it with your name and the word Gauss in the title, and send it to my mail.
3. Visit the rest of the pages and play with the shapes. Draw some sketches of them in your notebook.

## Cuboids, androids, and more…

Posted by ricardogm on 10th March 2011

Hi, peopleThis is an applet to work with cuboids (ortoedros, in spanish). Follow the instructions and write the answers in the notebook. I hope you like it.

• and now androids:
• and now more: If the cuboid of the applet were, for example, 3×3x3 cm, find the length of the diagonal of one face using Pythagoras, and then the length of the diagonal from one vertice to the opposite.
• and now a game, only for the brave.
