Students will already had some teaching on the purpose of circle graphs - also known as pie graphs (for example, that they are for data that is in parts of a whole or percentages) and also on the four types of exercise and how activities fit into those 4 types.

Students create a title for their Numbers spreadsheet.

Here is a good introductory video for Numbers: ]]> 2018-11-17 15:24:22 UTC https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305549050 An Example of a Numbers Spreadsheet ebuhr48 https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305549228 2018-11-17 15:25:58 UTC https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305549228 Using a Formula Feature on Numbers ebuhr48 https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305549523 Students drag the cursor down each column and then click on ‘Insert’ – ‘Formula’ – ‘Sum’ and the total number of minutes of exercise in that column will be calculated.  Students do that with each column (see example above).

-Were you surprised by these results? Why?
-How is the information in a circle graph shown differently than in a spreadsheet?  Than in a bar graph?
-Is a circle graph or a bar graph more reflective of how much exercise a person is getting during a week?  Why?
-When would you use a bar graph?  What information would be better suited for being displayed in a circle graph?
-Did using Numbers to make the graph help you understand graphing more or less than before?  Why or why not?
-Would you want to change how you exercise?

-Incorporate goal setting for physical fitness (B. C. Grade 7 Career Curricular Content).
-A class circle graph could be created of all students' data.
-Make a second pie graph that shows all the physical activities as a percentage of the whole (students would highlight the entire table except for the totals to do this).
-Broaden the health portion of this unit to include the kinds of foods (based on food groups) that students eat in a week.
-Translating percentages displayed in a circle graph into quantities - as fractions or decimals (B.C. Grade 7 Math Curricular Content).

Numbers as a technology tool can allow students to engage in analytical tasks, for example exploring the relationship between different kinds of graphs.  Students can analyze in very visual ways what kind of graph best suits different kinds of data, compare and contrast graphs, and focus on the data in different ways to highlight different conclusions.  Using Numbers to create the graphs was very motivating for me and I think it would be so for students as well, incorporating technology in what might be seen by some as a boring graphing unit.  Additionally, learning Numbers equips students to use this tool for many personal applications, from budgeting to record keeping.]]> 2018-11-17 15:49:36 UTC https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305552028 Two Worksheets to Extend Students Understanding of Circle Graphs ebuhr48 https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305553746 These are two worksheets I created to further students' understanding of circle graphs:]]> 2018-11-17 16:01:39 UTC https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305553746 Infographic of Canadian Children's Exercise Physical Activity ebuhr48 https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305554990 I would show this poster to students as a way to further discussion on promoting physical activity and to look at how information is conveyed through graphs.]]> 2018-11-17 16:10:24 UTC https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305554990 Works Cited ebuhr48 https://padlet.com/ebuhr48/zvhsvj3mqm8e/wish/305555512 “Circle Graphs / Pie Charts”.
