We shouldn't abbuse of magistral classes, but sometimes we need them

Gymkhana in Benamahoma

We are five teachers in our bilingual group: one of Natural Sciences, another one for Arts and Crafts, the language assistant, the bilingual coordinator (she is an English Teacher), and I, as a maths teacher. A social sciences teacher is supposed to be with us, but finally, we still don't have any.

However, last year, when we were preparing some materials and activities for this course, we used to work in the integrated curriculum, chosing one unit of social sciences and trying to prepare activities in our subjects related with that social sciences unit.

For the first term in ESO 2nd Course, we prepare an excursion to Benamahoma, related with the unit about Arabic Age in Spain. We prepare a Gymkhana in Benamahoma with several quizes related with maths, natural sciences or Arts and Crafts, and, later, we walked the path from Benamahoma to El Bosque along the river, searching some species between such biodiversity.

Here are some of the files related with this activity.

• Benamahoma map 
• Preparation for teachers
• Quizes 
• Presentation in order to prepare the visit.

Here you can read a blog post about this day in the language assistant blog.

Sexagesimal System

The numeral system applied to the measurement of certain magnitudes in which each unit is divided into sixty units of lower order is the sexagesimal system. This system is used for measuring times and angles.

You can practice with the following activity. You will need the program JClic, and once you got it, you can download this activity:

• Sexagesimal System

Once you have your download (you have to click on the button "Download Original"), you open the programm JClic, and you click on "Archivo", "Open" and you look for the file.

We hope you will enjoy it. See you soon!

Working with decimal numbers

In order to work with decimal numbers, we are going to practice shopping.

We are going to the market with a shopping list. Read this file and answer the questions in a white sheet, where you will write your name:

• Buying At The Groceries 

Later, you will be able to work with a calc sheet in order to test your previous work

• Calc Sheet

 We are sure you will have learned a lot with this activity

Vocabulary about integer numbers

Practice with divisibility vocabulary

Try to solve this crossword. You may win a prize if you are the first one.

Activities related with divisibility

In this class, we will play activities related with divisibility: factors, multiples, etc. In order to make that, we will use our computers, and we will visit the following links:

1. The factor game. We will start playing in pairs: one versus the other. Later, we will play one pair versus other one. And so on until one half of the class is playing versus the other half.
2. The product game. This game is a bit more difficult, but the use of strategy makes it more interesting. Don't get bored and play! You can be a really good mathematician.
