Week 8- End of Term Project Instructions
4th Grade Mathematics Term Project: Graphing
For your term project, you are required to collect data and create multiple graphs that you will post on your webpage under Math Term III. The data you collect will be based on a topic of your choice (topic must be approved by teacher). You will be responsible for collecting the data and recording it from multiple sources suggested on the timeline below. Once you have collected all your data you will create a rough draft on graph paper of the 3 different types of graphs we have been learning about. Follow the timeline below to ensure you stay on track!
Week 1 (May 11-15): This week you will use to brainstorm your topic/question. You must pick a topic that will allow you to create (at least) 10 categories. You will be given a brainstorming sheet, please keep it in your notebook attached to this sheet. You must check with your teacher that your topic is appropriate to use.
Week 2 (May 18-22): This week you will collect your data. Keep your information in and organized chart, attached to this sheet. Every time you collect more information add it to your data sheet. You may use multiple sources to find information. (I.e. asking peers, family members, friends, the Internet, magazines…). You will have class time to do some research.
Week 3 (May 25-29): This week you will organize the data you have collected into a frequency table or tally chart. Display the data clearly to ensure it will match with the graphs you will create. You will create your table on paper, and attach it to this sheet. You will also make a rough draft all the graphs you will be making online.
Week 4 (June 2-5): This week you will be creating your online graphs and online table. First, go to Word and create a table to display your data. (Click inset table, and choose the number of rows you need. You should have TWO columns; the categories and their value. Save your table and upload it to your webpage.
Second, create the graphs. To create use this website: (The link will be on the fourth grade weebly page) http://nces.ed.gov/nceskids/graphing/classic/
You must save the table with your data, as well as each graph you make. (To save, right click the image. Once saved, upload each graph to your webpage.
After you have saved and uploaded everything, your teacher will see the work you have done in Weeks 1-3. You should have this sheet, your brainstorm, you data collection, your handwritten table and graphs.
Should you need help, there will be an example on the gc fourth grade weebly page.
