The application is not intended to be used independently by the student, but as part of an educational class sequence.

************************************************** *************************************

Type: Simulator / Trainer / Issues Bank

concerned Cycles: Cycle 4, second

Base Area: 4

Targeted skills :

Probability: Understand and use elementary probability;

Data processing: Read as raw data of the data table, graph.

Description: Probability is a companion app for teaching probability in college and second. It is composed of three parts: Simulate; practice ; reflect

I. SIMULATION:

This part simulates many experiences, so as to introduce the concept of probability based on statistical frequencies.

content:

- dice Throws: (6 faces: 1,2,3 or 4 dice - faces 8: 1 or 2 Dice - 12 faces: one or two dice, dice Sicherman)

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be accumulated.

The data is displayed in a table

A chart is created in real time.

- Shots parts (1, 2 or 3 parts, faked or not)

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be cumulés.R

The data is displayed in a table.

A chart is created in real time.

- prints in a box (up to 4 colors balls)

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be accumulated.

The data is displayed in a table.

A chart is created in real time.

- lottery wheel (up to 5 colors sectors, number of configurable sectors)

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be accumulated.

The data is displayed in a table.

A chart is created in real time.

- Throws a bug:

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be accumulated.

The data is displayed in a table.

A chart is created in real time.

- Card Draws:

It is possible to simulate 1, 10, 100, 1000, 10,000 or 100,000 successive throws.

The throws can be accumulated.

The data is displayed in a table.

II. PRACTICE :

Exerciser part of the application, this is to train on the notions into classes.

content:

- Experiments to test: (series of 10 random questions, written exercise)

The questions are generated from 10 situations:

* Algorithm with Scratch

* Geometry

* Table double entry

* Frequency Table

* Draw from an urn (probability calculation)

* Print from an urn (calculating the number of balls)

* Lottery Wheel

* Letters Panel

* Draw a card

* Bar chart

- Experience in two events: (4 issues available, no year noted)

* Successive Shots of a part

* The Funfair

* Customer service

* Dress in Black

III. REFLECT :

This part includes a bank of six problems involving probabilities. Each time, the problem is stated, it is possible to play a game, then simulate a large number of party. Then load the students to find the exact value of the desired probability ...

content:

* Paradox of the Grand Duke of Tuscany

* Monty Hall Problem

* Free-tile game

* Monte Carlo method

* Moving a beetle on the edges of a cube

* Signes maps Game
