Introduction

Two spanish students have decided to introduce their school and welcome every body involved in the project.

Algebraic Identities with origami

In Spain, we carried out an activity to explain the demonstration of two important algebraic identities:

(a+b)²=a²+2ab+b²

(a-b)²=a²-2ab+b²

For such purpose we built two different figures using origami: a boat and a rooster

Christmas Origami Cards

The Romanian students received from their peers from Turkey Christmas cards.

It was a wonderful surprise.

Thank you very much, dear colleagues!
