This blog has two main themes: one is mathematics and the other is multimedia. The mathematics part will discuss ideas behind mathematical concepts from elementary to undergraduate topics. For now, I will be concentrating on discussing mathematics concepts from Grade 6 through Grade 12, although, from time to time, I might post topics in lower or higher levels. The multimedia part will discuss the use of different media such as text, graphics, sounds, video and animation in teaching mathematics. I will refer readers to multimedia and Web 2.0 teaching resources that can be used in teaching and learning mathematics, and I will discuss how-to tutorials on the use different software, particularly freewares. Unfortunately, most software that will be discussed in this blog are only limited to Windows platform, although many software nowadays are already cross-platform, so Linux and Mac users are invited to check the tutorials from time to time. Hopefully, I would be able to discuss software with other platforms in the future.

Now you can create your own sign generator! Just find (take your own with a digital camera, maybe a DVD still image grab, search graphics sites, take a pic from TV, etc) an image of a sign or a photo where there is a clearable area to place text. Use GIMP (best freeware photo editor) to clear out the text area (if there is text already in the way) and then import it to this site to manipulate the text with hundreds of fonts, also make sure the image size does not exceed 650 pixels (height or width). You can even use a photograph of yourself (use free hosting so you have a web URL to use) or loved ones and add comic book styled bubbles (sample) where you can change the text characters to suit your needs (captionize your photographs), you can literally turn any image or clipart into a sign generator!
