1. Gather ‘Round the Tables Interpreting Data Tables

2. Most of the Data Tables that your students will see or make in math or science class, or on the TAKS, will be very simple and straightforward.

3. PENNY'S NEW FLOWER GARDEN (available as a printable worksheet at www.teach-nology.com)www.teach-nology.com Flowerpinkwhitepurple Daffodil16300 Iris214326 Day Lily14120 Azalea24930 Roses750 Penny couldn't wait to make a new flower garden in her back yard. She got the soil ready for the new plants. Here is a table of what she planted in the new flower garden. Read the table and answer the questions. You will need a pencil to work some of the problems.

4. Flowerpinkwhitepurple Daffodil16300 Iris214326 Day Lily14120 Azalea24930 Roses750 1. What is the total number of Iris bulbs Penny planted? ______ 2. How many roses did Penny plant all together?___________ 3. What plant did Penny plant the most of?_____________ 4. How many more white Daffodils did she plant than pink?_______ 5. What is the total number of purple flowers Penny planted? ______ 6. What is the total number of roses she placed in the garden?_____ 7. How many more purple Azaleas than pink Azaleas? ________ 8. What is the total number of Day Lily plants? _________ 9. What is the total number of pink flowers?___________ 10. What plant did she use the least in her garden?_________

5. But when you get data sets from real-world applications, it can sometimes be difficult to know what to look for.

7. Luckily, the websites where you get the data often have graphs, maps, or other visual aids to help you interpret the data more easily.

8. Earthquake maps of US and the World Red Red = in the last hourSize of the square is in scale to Blue Blue = in the last daythe magnitude of the quake. Yellow Yellow = in the last week

9. Of course, you can always have the kids do the graphing or mapping themselves, and the next two webinars will be about graphing. Got Data - Need Graph! Choosing and Making Graphs Wed., Dec. 9 th and Sun., Dec. 13th Given a data set, choosing the best type of graph to represent the data, as well as how to determine range, axes, etc. and construct the graph. Grappling with Graphs - Graph Interpretation Wed., Dec. 16th Given graphs, we will get specific data, look for patterns, and interpret what the graph tells us.

10. Some Good Sites for Data Sets Statemaster: – Statistics by state of tons of different interesting things - many graphable and mappable – Gathered from many government sources (census, school districts, state fovs, etc.) – http://www.statemaster.com/ http://www.statemaster.com/

11. USGS: United States Geologic Survey – Statistics on natural disasters (earthquakes, volcanoes, tornadoes, floods, hurricanes, etc.) – Large raw data sets, as well as static and interactive maps – Up-to-date information (sometimes to the hour) – Some volcanoes are monitored with live video cameras – http://www.Usgs.gov http://www.Usgs.gov
