App generated by GXWeb || CAS and numeric tools by Nerdamer and MathJS || HELP?

When entering mathematical expressions in the math boxes above ( $f$ , $g$ and $h$ ), use the space key to step out of fractions, powers, etc. On Android, begin entry by pressing Enter.

Type simple mathematical expressions and equations as you would normally enter these: for example, "x^2[space]-4x+3", and "2/3[space]". For more interesting elements, use Latex notation (prefix commands such as "sqrt" and "nthroot3" with a backslash (\)): for example: "\sqrt(2)[space][space]". More?

Share with QR Code

Back to Top

QR Codes are a great way to share data and information with others, even when no Internet connection is available. Most modern devices either come equipped with QR readers in-built, or freely available.

The default link here is the GXWeb Jigsaws and Quizzes, but you can use it as an alternative to sending your assessment data via email, web or share with others in your class. You can even use it to send your own messages!

Turtle Robot Controls

Back to Top

Imagine designing, building and even remotely controlling your own robot! It is probably easier than you might think!

Alternatively, grab a TI Innovator Robot already made and follow the directions to "hack the hub"!

Watch the YouTube video of our GX Robot.

Follow the tutorial step-by-step directions to build and program your Arduino or TI Innovator robot.

NOTE: If using iPad or iPhone, you will need to grab the free Bluefy app to access webBluetooth since most browsers on this platform do not have this capability.

Then just connect and use your LOGO commands to steer - or use the controls below to connect and drive!

NOTE: Different surfaces and different robots will require different traction values. Try different values for distance and turn angle here until you find those that work best for your situation.
