Θεματογραφία Μαθηματικών Διαγωνισμών από όλον τον κόσμο.
Περισσότερα από 20000 θέματα.

και για τους Ελληνικούς Μαθηματικούς Διαγωνισμούς από την Ε.Μ.Ε. εδώ και γενικότερα για εξάσκηση στο www.mathematica.gr.
Ειδικότερα, θέματα για όλους – εισαγωγικά εδώ, γενικά ομαδοποιημένα θέματα για διαγωνισμούς και γενικότερα ακόμα ενδιαφέρουσες ασκήσεις για μαθητές και μόνο. Σε όλες αυτές τις κατηγορίες οι μαθητές μπορούν ανάλογα με το επίπεδό τους και το ενδιαφέρον τους να εξασκηθούν σε σημαντικά κομμάτια είτε της ύλης των διαγωνισμών, όπου εμφανίζονται ιδιαιτέρως ενδιαφέροντα προβλήματα, αλλά και θέματα εκτός μαθηματικών διαγωνισμών που εφάπτονται της ύλης του σχολείου και ενισχύουν την κοινωνική οπτική τους.
Η εγγραφή σε ένα φόρουμ σχετικού με μαθηματικά και η ενεργή συμμετοχή στη συζήτηση αποτελεί συμπληρωματική και ουσιαστικότατη ενέργεια στην επίλυση ενός προβλήματος, διότι διαφαίνονται τόσο οι σκέψεις, όσο και οι γενικότεροι προβληματισμοί του λύτη.
