Então disse à mãe:
- Mãe na nossa árvore temos o mesmo número de bolas que a minha idade, o mesmo número de asas de anjos que a tua e o mesmo número de pontas de estrela que a idade da avó.
a) Que idade poderão ter a mãe e a avó do Carlos?
b) Quantas bolas, anjos e estrelas poderá ter a árvore do Carlos?
Carlos is eight years old and decided to count the Christmas ornaments on his tree and noticed that he had balls, angels and stars in a total of 33 ornaments like these:
Then he said to his mother:
- Mummy, on our tree we have the same number of balls than my age, the same number of angels' wings than your age and the same number of star edges than the age of grandmother.
a) How old could be the mother and the grandmother of Carlos?
b) How many balls, angels and stars may have Carlos' tree?
Knowing that there are 2 billion children on the planet, estimate how many presents have Santa Claus and the elves to make a day in a 365 days year?

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)

Move three matches to get four triangles.
Someone has stolen Santa's wish list. He doesn't know how many presents he still has to prepare. Help him and guess what is the number ?
3 3 1
2 1 2 1
1 1 1 1 1
There are 9 snowmen in the box. They have got 9 baby-snowmen. How many legs are there in the box ? :-) Be wise ;-)
