Classpad :: eActivities
eActivities are a great way to see how you can use your Classpad to go beyond the basics. eActivities can be downloaded and sent to your handheld using the USB cable and free software that came with your Classpad.
Cascade type eActivities. Nearly all the eActivities below are re-usable templates for carrying out a series of steps to solve a problem. I think of them as 'cascade' type eActivities, as you simply modify some of the initial variables, tap EXE and the whole problem is re-calculated step by step from top to bottom.
How to Download - how do you get the eActivities from this page into your Classpad?
- If you have Classpad manager running on your PC, simply click the link to any Classpad file and choose the 'Open' option. In a few seconds, the Manager will open and you'll find the eActivity or file already loaded (and saved). So easy!
- If not, choose the 'Save' option and then visit casioed.net.au, the official Casio Education Australia home. Go to the Classpad downloads page and grab a copy of the article 'Working With and Managing Content'. Almost as easy!
 2PointLine At the top of this eActivity file, change the coordinates of two points and watch as just about everything you want - equation of line through points, distance between them, midpoint, perpendicular gradient, etc is calculated. As a bonus, all the formulas used are clearly visible and just like those found in most text books - so you can see how everything is calculated! Download 2PointLine now!
 TriArea3Sides Use this eActivity to find the area of a triangle when all 3 side lengths are known. Edit the 3 side lengths and instantly the semi-perimeter and area are calculated and displayed. Both formulas used are clearly visible so you can see how everything is calculated! Download TriArea3Sides now!
 NormalCalcs Use the normCDF function in a NumSolve strip to solve for any of the variables, including the mean and standard deviation. Download NormalCalcs now!
 TrappedArea Modify the two functions f(x) and g(x) at the top of this Main strip and tap EXE. Then use the solutions to f(x)=g(x) to set the limits of integration and the trapped area is calculated. Did that take 20 seconds? Too easy! Download TrappedArea now!
 AvgRateChange A Main strip saved in an eActivity for calculating the average rate of change of a function between x=a and x=b. Simply modify f(x) and the values of a and b and tap EXE. If the Main strip is set to Standard mode, then approx() automatically gives a decimal approximation to the exact value. Download AvgRateChange now!
 DiffFirstPrinc A Main strip saved in an eActivity for finding the derivative of a function from first principles. Simply modify f(x), tap EXE and copy down some working for full marks! Download DiffFirstPrinc now!
 ClosestAppCalc A Main strip saved as an eActivity to determine the time and position of the closest approach of two moving points A and B using a mixture of vector and calculus methods. Simply modify the initial position and velocity vectors for A and B and tap EXE. All the expresions are re-calculated and you have plenty of working to copy onto your test paper! Download ClosestAppCalc now!
 ClosestAppDot Similar to the previous eACtivity, this is a Main strip saved as an eActivity to determine the time and position of the closest approach of two moving points A and B, only in this case using purely vector methods. Simply modify the initial position and velocity vectors for A and B and tap EXE. All the expresions are re-calculated and you have plenty of working to copy onto your test paper! Download ClosestAppDot now!
