Workshop on using freeware to enhance learning and teaching of Mathematics in secondary schools
Simon Leung
2
Programme Description
1. Introduction of popular freeware on Mathematics (e.g. WinGeom, WinPlot and Winstats).
2. Hands-on practice of using some of the freeware.
3. Experience sharing on using freeware to design teaching and learning materials for Mathematics in secondary schools.

Why use the software?
• Free
• Can Save file
• Student can use it at home
• Easy Installation
• Exploring/ Discovering Learning
4
Software Installation
• Create a new folder “maths” in c:\
• Download the software from
• http://math.exeter.edu/rparris or• http://iclassroom.hkedcity.net/teacher/maths • Send the shortcut to Desktop
5
Launch the program
• Click the WinGeom Icon(yellow triangle icon)
• At the green screen, select Window 2-dim• Maximise to fill your screen
6
The WinGeom
7
Basic Function-Use of ToolBar
• Start afresh with a clean sheet on the screen
• Btns-> Toolbar• Select Segments• Right click to plot point• Left click and drag to create line se
gment• Or Choose LINE SEGMENT to
create segment
8
Create the following diagram
Use of the segment, rays, lines, circles and drag vertices
If the label overlap the point, choose Edit Label Offset
9
Text edit
• Select text edit
• Mouse over the point and right click
• Change the label
• Or Edit Label SWAP
10
Measuring Angles, Lengths and Area
• Draw a traingleMeas • Enter AB for the length
of segment AB.
• Enter <ABC for the size (in degrees) of angle ABC.
• Enter ABC for the area oftriangle ABC.
• Enter [slope](A,B) for the slope of a segment AB
11
By observation, Student draw conclusion for
• Angle sum of triangle
• Properties of Isosceles Triangle
• ……
To extend a line, Choose LINE EXTENSIONS

Using WinPlot to Plot Graph
•Click the WinPlot
Solve y=(x-1)/2
y=(-2x+12)/3
Graphically
14
Set the Grid
• View Grid
• Adding a grid to your graph.
15
To plot the graph
•Equa Explicit
•Input the equation (x-1)/2 in the dialogue box .A line will be plotted
•Use Page up and Page Down to zoom in and zoom out
16
To show the equation
• Choose Equa Inventory
• Changing the width and color of your function.
To move the equation towards the line, choose Btns Text
17
To find the point of intersection
• Two Intersection
18
Viewing window
• To move around the plane. Using the Page Up and Page Down
• To Specifying the corner points in the graph window. Choose View View
• To redraw. Choose View Redraw
19
Copy image from WinPlot to Word
• Importing the function into Word.
• Importing a number line into Word.
