MERRY CHRISTMAS EVERYONE:-)

Christmas tree equation



Λίγο πριν τα Χριστούγεννα οι μαθητές έψαξαν στην αποθήκη του σχολείου να βρουν τα περσινά χριστουγεννιάτικα δέντρα και να στολίσουν τις 17 αίθουσες του σχολείου. Βρήκαν 6 πράσινα, 8 χιονισμένα και μερικά άσπρα. Πόσα ήταν τα άσπρα δεντράκια;
(να λυθεί με εξίσωση)


Few days before Christmas some pupils went down the school’s basement to find last year’s Christmas trees. They wanted to decorate the 17 study rooms of their school. In the basement they found 6 green trees, 8 trees with fake snow on them and some white trees. How many are the white trees?
(you should solve it using an equation)

Merry Christmas everyone and happy new year

Prime numbers


When my teacher was asked about his age, he answered:
 “My age number is a prime number*, but if you reverse the digits the new-formed number can be divided by 5. Moreover, I wish I live up to this age”.
Can you find my teacher’s age?


*prime number is a number that can be divided only by 1 and itself e.g. 11 is divided only by 1 and by 11.



Πρώτοι αριθμοί
Όταν ο δάσκαλός μου ρωτήθηκε για την ηλικία του, απάντησε:
«Η ηλικία μου είναι πρώτος αριθμός αλλά, αν αντιστραφούν τα ψηφία διαιρείται με το 5 και ελπίζω να ζήσω τόσα χρόνια».
Πόσων χρονών είναι ο δάσκαλος;

Greetings from Drama, Greece


Hello dear partners
We are the 6th grade of 13th primary school of Drama, Greece.
We are happy to join you in this project.
I’m sending regards on behalf of the pupils
Dimitra Theodosiadou


Hello from Estonia!


First of all - we are very happy to be involved in such a great project!

Our students have already solved some of the problems. We've had lots of fun!
Now, I'd very much like to post photographs of students' notebooks as answers to this blog but it seems that it isn't possible to post any images as
a comment.
I think pictures from notebooks would make this project even more lively, and it would be very interesting to see how kids from different countries find answers and what the layout looks like.
Can we do anything about it? Of course, several kids work on the same problem, but only the best looking/right solution would be published here. Being published would be
as a prize for kids and I'm sure it'd motivate students to work harder.

Anyway, I'll post our best solution to the fox-bear-fish-problem here.
The author is Silver, Year 1.

All the best!

An Unpleasant Trick !!!


One day, Ebru asks her friends to give her their watches to play a trick
on them.Just not to make Ebru upset Erdoğan,Gizem,Furkan and Berkay without
knowing what they will face give her their watches.Ebru sets the watches that
she had taken from her friends a few minutes backward.
Before Ebru borrows Erdoğan,Gizem,Furkan and
Berkay’s watches,their watches show the correct time as they are written below
:
Erdoğan’s watch is 3 minutes back from the actual
time.
Gizem’s watch is 10 minutes back from the actual
time.
Furkan’s watch is 4 minutes back from the actual
time.
Berkay's watch is 9 minutes back from the actual
time.
When Erdoğan,Gizem,Furkan and Berkay take their
watches from Ebru,they realize that there is something wrong because it has
already been too late and they had realized what was wrong too late.
So, in accordiance to this:
1)When Erdoğan’s watch shows 12.35, what time does
Furkan’s watch show?
2)When Berkay's watch show 15.30, what time does
Gizem's watch show?
3) If these four friends went to meet each other
at an arranged time ,what time difference would there be between the one who
comes the second and the one who comes the fourth? ( Taking their own watches’
time in to consideration)
