3. Introducing our new T.A.

Maggie Wright is our new T.A. She will share some of our classes and will help us (me too!) improve our English.

If she's going to be with us for the rest of this school year, we'd better know something about her.

Please, ask Maggie questions about her past, present and future; about her likes and dislikes; about anything you might think interesting to know ...and note down the main information because this task consists of writing a composition (150-200 words) about Maggie.

Don't hesitate to include any means available to you (pictures, recorded audio,...)!
If you need help with your English, don't hesitate to ask Maggie or me
Remember to work together with your team mates and be careful: no intimate questions are allowed!!!

Deadline for uploading your essays to your team blogs: 23rd October.

2. Performing mathematical operations

Last year's 101 Media Production students took an initial test in mathematics. 
You have also reviewed some basic maths during these first weeks of class activities. Please, take a look at the aforementioned test; you'll surely find it quite easy!!!

Well, now it's time for you to explain the steps that lead you to the correct answers to (at least) three of the problems set in the exam. And this has to be done in English, of course!!!

Please, use a PowerPoint/Prezi/Slideshare presentation to explain each step you take for solving the problems --and don't forget to specify the role each member of the team took to fulfill the task.

Deadline for delivering the blog post: 17th October
