How many decimals can you memorize?

Finally, do you know what day in the year is Pi day?

It's now your turn, use pictures you create from the Whiteboard app, pictures from the web, the REEL DIRECTOR app, the microphone, and your iPod to create a one (1) minute video about the relationship between the diameter and the circumference of a circle.

Congratulations!!! Graphs Improved!!!

Our class noticed that lines from the y-axis on a news channel's weather forecast were confusing.  Those pictures  moved our class to send observations to the channel.

After your efforts to contact the news channel, the graphs are improved!  The video shows how they have removed the y-axis.  While from a math standpoint, it should still be there, the intervals are not incorrect and less clutter on the graph has produced a clearer representation of the data.

Analyze the pictures with the information and ask your self:

   "What's wrong with both of them?"  "How can they be improved?"

Thank you Fox 11 for sending our class clear pictures of the graph.  A discussion of the response will be conducted in class.
