# Unit 3: Locating Existing Concept Activities for the Nspire

Back to course outline: Better Understanding of Mathematical Concepts through the Graphing Calculator

## Objective: By the end of Unit 3, you should be able to locate and alter existing graphing calculator concept activities to use in lessons.

In the previous unit, you thought about a unit of study that your students have struggled with. Now you will locate existing activities through the Internet for the Nspire. There are many great activities that TI and other educators have already created. You do not have to create everything from scratch especially when you are first starting to incorporate the Nspire into your lessons. The activities range from 5 minutes to 1 ½ hours, so make sure you check the estimated time to completed when you consider the different activities.

### Example Activity

Here is an example of an activity found on the Internet. It is called "Variables on Both Sides." It is used to help students discover that a linear equation with one variable can have 0, 1, or infinitely many solutions. Students drag points on number lines to discover when both sides of the equation are true. Below are some snap shots of the activity:

The entire activity can be found at the following website. The website includes links to the tns file (this is what files that are created for the Nspire are called) and activity worksheet. [[1]]

### Tips for Selecting Activities

As you search the below links, keep the following in mind:

• Be selective when looking at activities. Only consider activities that target your learning objectives for that lesson or unit.
• Select activities that you think will increase your students’ understanding of the concept based on the research you read in Unit 2. Don’t pick an activity just because it seems fun.
• Remember you can always alter an activity by downloading the worksheet as a Microsoft Word document and downloading the tns.file on to your computer to open and change. This might be helpful if you find a good activity that is too long for your class period or just needs to be changed to better fit your students’ needs.

• Click on the link [[3]]
• Select the publisher of your textbook.
• Navigate the website to find your textbook.
• If your textbook publisher is Holt McDougal, you will see a variety of textbooks. Click on the one that is yours and then scroll through the list of chapters and sections to find the one you want. Once you find the section you want, you can click on the link and find many activities that can be used with that section.
