Western Bulldogs Number Place Logo

This post was inspired by Simon Job. He has used Geogebra to produce co-ordinates of the outline of a picture. These co-ordinates are then transferred to Excel and then pasted into Word to produce a “Join the Dots” activity to give students practice at locating points on a cartesian plane. His Brisbane Broncos Number Place Logo was posted on 20 Sep, 2009.

I particularly liked Simon’s idea, so I set out making one of my own. Unfortunately I soon became frustrated because I couldn’t work out how to paste a picture into Geogebra. Is this only available in the Apple version? So I started to think about what software I had previously used that could work. My memory still works sometimes and I recalled DigitiseImage.

So I looked at all the AFL clubs and then imported the Western Bulldogs logo into DigitiseImage. I then set the scale and clicked on points all around the logo.

I then clicked the open in Excel button. Having the co-ordinates in Excel is a great advantage. You can easily transform the drawing. For example: moving between quadrants (=A1-10) and changing the scale of the drawing (=A1*4). I also checked what the final diagram would look like with the following:  Insert Chart, XY Scatter.

This is what my bulldog now looked like:

Notice that the Excel scattergraph will not join points back up to the starting point! No worries, now paste into a Word document.
