Aim: students will be able to understand the algorithm.

Procedure:

The students should guess the number from 1 to 1000 with the help of 10 questions. This time it was Yes/No number guessing game. It was rather logical as the next step of our class was the revision the way numeric data like 0,6; 11.68; 12,356 is said.

First af all we have revised the characterristics of the strong questions. Then students had a chance to guess the number for 10 questions. They succeeded and the questions they have asked surprised me as they were thinking ones like:

Is this number more than 500?

Is this number more than 250?

How many digits are there?

Does it consist of equal digits?

Is this number between 77 and 99?

There were only 2 just guessing questions.

The second round the student who guesses the number thought about another one and the students should guess for 5 questions. The next surprise was when they have managed to do it for 2 questions.

Feedback:

I was glad to hear that the students were excited to hear that we are going to play a guessing game again. I think that all the students have understood the characteristics of strong and weak questions.
