Today I've been working on an idea for the interactive whiteboard using PowerPoint which I've called Jigsaw Puzzler. An adaptation of the classic overhead projector 'keyhole' technique of revealing an image one piece at a time, the presentation combines the Four Interlocking Puzzle Pieces from PowerPoint's Autoshapes with the drag and drop macro written by Hans Werner Hofmann and Ute Simon.
Once you've downloaded the jigsaw puzzler presentation, you need to click on the Tools Menu, then Macro/Security, select Medium and click OK. Next paste any set of images or text boxes into the template and send them to the back by right-clicking an image and selecting Order/Send to Back so they cannot be seen when the presentation is launched.
Click Slide Show/View Show or hit the F5 key and you will see a message asking you to enable macros. Click the Enable Macros button and go to the second slide by clicking on the bottom right Action Button. Once there you will be able to click on individual jigsaw pieces and move them to one side to see what is hidden underneath, be it a picture or text. Please note the pieces around the border cannot be moved.
Once pupils have guessed correctly, they can go to the next slide by clicking on the bottom right Action Button or you can press the relevant number for a particular slide on your keyboard and hit Enter to take you there immediately in Slide Show Mode.
This is a work in progress. So please try it out and tell me what you think.
