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.

### Wrapping Presents

### Christmas Ornaments

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?

### 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**

### An Unpleasant 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)

### Hello friends

We're happy to join Fun and Maths project. We hope our ideas will be useful for you and your students.
