Maths Quiz and Mental Sums.

Class 5-5 did a math quiz today. I thought that it was interesting and novel as problems like these doesn't come everyday in mathematics; not when one is still learning concepts of mathematics. I remembered one question in the maths quiz consists of looking for a pattern which is known as a Fibonacci number.

In mathematics, the Fibonacci numbers are a sequence of numbers named after Leonardo of Pisa, known as Fibonacci (a contraction of filius Bonaccio, "son of Bonaccio"). The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to the sum of the previous two numbers of the sequence itself, yielding the sequence 0, 1, 1, 2, 3, 5, 8, etc.

Now the question is;
Why are we learning all these problem solving when we don't even use them in real life?
The answer to this is not learning to apply. Instead, we are learning to be exposed to different patterns and while constantly looking and solving these patterns, we are using our thinking skills and training our mental ability, so that we are improving on our short-term memory.

Okay... enough of all these theories. Let's have some fun instead.
What I am going to do is I am going to attempt to read your mind. Yes! Reading your mind through your computer screen.

"Look at this picture, choose a card in your mind and remember it."

Mind reading in progress....15%



...45%



...58%


.....84%



....99%

Done!

The card that you have picked in your mind is gone!

To students of 5-5,
How does this work? Am I really reading your mind? Or is there another possible explanation for this?

You might want to post your "solution" on the tagboard.
