Flashcards - Problems

Flashcards is a great tool to use by pupils and by teachers! At Colégio Monte Flor we are huge fans of this web 2.0 tool created by Miscrosoft. You just need a windows live/hotmail account. If you don't have it's easy to creat one.

This year, our 3rd graders have been using a lot and so we decided to create a Flashcard Deck with some funny problems you can solve during Easter Vacations!

Access this Flashcards Deck by clickin here.

There are 24 students in the 5a form. Outside  -24 degrees below zero. Guess-how many students came to school? Correct answer- zero:-)

So-sorry, but we are taking a short break. My students are at home and we can't post any new tasks. Let's wait for better weather. Have a nice week:-)



Αυτή την περίοδο στην Ελλάδα έχουμε εκπτώσεις. Με δεδομένο το οικονομικό πρόβλημα της χώρας και της αγοράς, μπορεί μερικές φορές να βρούμε ένα προϊόν καλής ποιότητας σε χαμηλή τιμή. Έτσι αποφασίσαμε το πρόβλημα του μήνα να αφορά την περίοδο των χειμερινών εκπτώσεων.

Η Έλενα ήθελε να αγοράσει ένα φόρεμα για το γάμο της ξαδέρφης της. Της άρεσε πολύ ένα που βρήκε άλλα της φάνηκε ακριβό, 250 ευρώ. Ευτυχώς είχε εκπτώσεις και στη βιτρίνα του καταστήματος η ταμπέλα έγραφε 40% κάτω από την αρχική τιμή. Πόσο ήταν το ποσό της έκπτωσης; Πόσο πλήρωσε τελικά η Έλενα για το φόρεμα;

Αν ο μισθός της Έλενας είναι 800 ευρώ το μήνα, θα θεωρούσατε το φόρεμα φθηνό ή όχι;

These days it’s the sales period in Greece. Given the financial problems that the market faces we can find, in some cases, high quality products in low prices. Thus, we decided our math problem to be related with discount.

Elena wanted to buy a new dress because she was invited to her cousin’s wedding. She found a dress she really loved but it was quite expensive, 250 euro. Luckily it was sales period and the shop’s window had a big label “40% off the original prices”. How much was the discount? How much did Elena pay for the dress?
If Elena’s salary for the month was 800 euro, do you consider the dress’s price cheap or not?

Berlindes / Marbles

O Ricardo deu metade dos seus berlindes ao seu amigo Miguel, mas quando chegou a casa, a sua mãe tinha um saco com 25 berlindes para lhe oferecer.

Quantos berlindes tinha o Ricardo no início?
