This is a blog created to the Etwinning Project Fun and Math. A project directed to mathematics, focused on funny and stimulating activities for children, enabling them to gain some interest and pleasure for this subject, but also explore their logical-mathematical thinking abilities and skills. With this project we intend to share challenges, problems, online games and tasks that allow children to improve their performance in Math.

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.
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».
