# The "Probabilities" Series

In the "Probabilities" series of activities you discover, invent, and test your mathematical theories.

*These are a little more advanced, so please check out any suggested prerequisites. E.g., The Art of the Lynx, Create an Interactive Card, Interactive Story Project*

**Activity Cards & Guides**

Students will create a computer simulation to test the probability of an event, in this case of two people in a class having the same birthday. This activity can be modified to demonstrate the probability of other events, such as the chance of rolling the same number on a die or on multiple dice.

Students will code the computer to:

Stamp a shape for each personâ€™s birthday in a randomly determined location.

Create variables using sliders, and text boxes.

Create conditional statements to test conditions and control action.

**Grades: **5 - 8

**Time: **maybe 3 60 minute sessions

Students will code an investigation to see how trial size impacts the probability of an event.

Students will code the computer to:

Randomly choose an event

Set the number of trials for an investigation

Keep track of how many times an event occurs

Create a graph using the data

**Grades: 4 - 8**

**Time: **maybe 3 60 minute sessions

Students will create a Calculator Program.

Students will code the computer to:

Retrieve input from the user via text boxes

Create variables and store values

Create an interactive button

Perform operations on numbers entered by the user

Animate a shape using Repeat

Hide and show text boxes

Advanced options include:

Incorporating additional buttons and operations

Try coding other applications that require the same skills

**Grades: **6 - 8

**Time: **maybe 3 60 minute sessions

Students will create a gravity simulation.

This activity will allow the students to demonstrate how a object is affected by gravity and rolls down an incline plane or hill.

For this simulation and animation the students will use a ball to show what this might look like.

Students will code the computer to:

Locate objects using coordinates

Create backgrounds

Direct actions based on compass headings

Write procedures

Use buttons to trigger actions

Animate an object to simulate movement

Add a slider to create variables

Advanced options include:

Using more complex inclined plane

**Grades: **3 - 8

**Time: **maybe 5 60 minute sessions
