Only two more days to Easter!

Hi guys!

Don't go berserk, in two days you'll have the chance to let off steam in our 11-day holiday!

Meanwhile, you can check the solutions of those exercises here!

Notice that for the first two exercises, there are infinite possibilities ;) I'm sorry there was a mistake in the second one... hehehe... it should've been x=-2 and not x=2.

See you tomorrow!!!!

This song sound like holidays, doesn't it?

Welcome back to reality!! YEAH!

Hi guys!

I very much hope you've had an amazing week! Are you 100% ready for the next month?? :D

I've been skiing 250 km these past few days in Saarselka (North Finland, Lapland) with some friends. 

It has also been great to see the Baltic Sea completely frozen! O_o

You can download here the solutions for the extra bulletin to review the exam you will have in two weeks. 

See you tomorrow!!!

White Week Exercises

How are you doing! Here you are the solutions of the exercises I asked you to do these days ;)

Don't forget that on Tuesday you'll take the Second Evaluation Global Exam (and after some of your performances in the previous exam, it would be great for you to review equations and all that stuff... ¬¬)

Anyway, the weather up here is pretty much terrible and both Elena and I really miss you all. We know you can't live without us, so here's a song for you to moan our absence.

The Problem with the Hourglass

Some students have to take a test in 9 minutes. Due to an electromagnetic pulse, every watch has stopped working and we only have two hourglasses to measure time.

These two hourglasses (the only ones we have in the high-school) last for 7’ the first one and 4’ the second one. 

How can we measure exactly 9 minutes (neither one second longer, nor shorter) using these hourglasses?

Tip: try to start both hourglasses at the same time. What happens after exactly 4 minutes?

Deadline: October the 25th.

And we continue with the 90's...

Ismael's Problem

Ismael visits a one-floor castle with 64 rooms connected as described in the image below. He starts in the bathroom (the black square) and since he feels sooooo relieved he wants to visit the 64 rooms using only 15 straight lines.

Would you be able to help Ismael and draw a path for him starting at the balck square and using only 15 different lines ( without removing the pencil from the sheet) so he manages to visit the 64 rooms?

Watch it: You MUST start your trip from the black spot, but you can finish it wherever you want. Notice there’s one missing connection between two towns at the bottom of the drawing. 

Deadline: October the 11th
