The A&W Restaurants brand launched a 1/3 pound hamburger to compete against McDonalds' successful 1/4 pound hamburger, but nobody bought it because they thought that 1/3 burgers were smaller than 1/4 burgers!!!
The mistake: considering that as 3 is smaller than 4, the fraction 1/3 is smaller than 1/4.

Initial activity: Think and solve the following classic puzzle (version by Professor Francisco Durán Ceacero).
Two colleagues meet at the end of the years. After initial greetings, they ask each other about their families. One of them says:
I have 3 sons who have... By the way, you were good at maths! Well, listen: the product of their ages is 72 and the sum is exactly the number of the bus that is passing by. Do you see?
Yes, answers the friend; but... I'm missing a fact.
Ah, that's right, the eldest plays tennis.
How old are each of the children?

Project: Sea of zeros
We use our eva rubber to prepare material for class.
You must cut out 20 red and 20 blue squares of 1 cm x 1 cm.
Design a system to transport them (envelope, bag,...).
Instructions to work with our Sea of zeros.
We start working with your sea of zeros and the 20 tiles of the same size and shape of each colour that you have prepared.
Place all the pieces indicated in the centre (island).
Take as many as you can into the sea of zeros, knowing that in the sea of zeros there can only be pairs of tiles made up of one tile of each colour .
Write down which pieces are left in the centre, you have to write the number and the colour.
