DigitalLesson.com has been around since 2004. You can visit the website to see my current design and get an idea about the feel of the site.
You can also visit http://www.entrepreneurincomestreams.com to see the Wordpress version of the website that I am in the process of creating.
I will use the logo on a new header for the Wordpress site, as well as on actual digital products to be delivered, eBook covers, etc.
My target audience is middle school math teachers who would like to find valuable math lessons, projects, games, etc. online to download.
The logo should have some sort of picture component and the words DigitalLesson.com. The graphic should include a mathematics component but also focus on the digital delivery of products for teachers. The slogan "Powerful Middle School Math Activities" can be worked in if it fits with your concept. It would be nice to see the logo with and without the slogan.
The math activities travel from the computer to teachers around the country and even the world. Then teachers print them and use them in their classrooms.
