### Using Gliffy and Bubbleshare

In recent days I have introduced you to bubbleshare on-line embedded presentation tool, and gliffy an on-line embedded mind map tool. Both are great tools you can find at this wiki . As we enter the 3 unit for scribe posts I hope you will take advantage of new tools to show you understanding of the concepts being taught. When you use these tools it provides a better picture of what is being said instead of a paint bmp.

Here is a bubble share that explains the process of creating and embedding a slide presentation.

Welcome students to the third round of Scribe Posts. Your scribes get better all the time and I am looking forward to this next batch of posts.

As we discussed in class on Friday I expect all scribes to create a link in their post showing me where you left a comment outside of our class blogs. I will include an instructional screencast to show you what I expect.

Even if you are not a scribe I encourage you to leave comments at these sites. The more comments the better.

Here are the Classes that I know of that use Scribe posts in Math.

Schools that Scribe
S3 Math from Scotland

GeoBlog from Alabama
PreCal 30s Danial Mac
PreCal 40S Danial Mac
APCalc Danial Mac
Math Challenger

There will also be a link to classes that scribe on your sidebar.

It is important to show student from around the city and around the world that you are an audience for their writing. I know you will use appropriate language and leave creative, positive comments that will inspire those students to continue to blog.
