Lesson Idea - Math - Linear Graphs using real data.

What better way to learn compiling, arranging and presenting data than with real information. To practise making Linear Graphs, Missy used weather data from  the National Oceanic and Atmospheric Administration Website. She made a graph charting the daily highs for May 2010 of three cities in our area. 

Here are some screenshots to help you navigate. Click on the pictures for a larger and cleared image.

This is the NOAA's website. Enter in your Zipcode in the upper left corner.

Scroll down to the bottom of the page and click on 'Regional Weather Summary'

This is the page that will pop up. In the section for 'Climate' click on 'Local'

This is the page that will open up. From 'Product' click on 'Monthly Preliminary Climate Data', choose your location and then choose the 'Archived Data' option. Now your child can choose which month's data to retrieve. 

 We really enjoyed making the graph on quadrant paper using different colors for different cities. Missy also calculated the median, mean, range and mode.
