L.O. To present data in the form of a pie chart.


To complete a pie chart, you will need a protractor. If you do not have a protractor at home, you could use estimate, using an online one or present your data as a bar graph instead.


Today, you will be starting with a large bag of skittles, beads or anything that has an assortment of 5-6 colours. You could use lego, for example. You will need to count out either 36 or 72 coloured pieces, and then tally how many of each colour there are.


Next, you will calculate how many degrees of the circle each colour is worth. If a circle is 360 degrees and you have 36 skittles, each skittle would be worth 10 degrees. If you had 72, what would each one be worth? So, if I had 36 skittles and 8 of them were orange, then 80 degrees of my circle would need to be orange.


You will now make the pie chart. It would be helpful if you had a compass, as you can see a clear centre point, however you can use a circle template if you don't. Using your protractor, measure each colour. You can look at the guide attached to help you. Once you have completed every colour the circle should look finished with no overlap or leftover space. 


Extra Challenge: Write three word problems for a family member to complete, based on your pie chart results. You can talk through the answers afterwards. Example: Based on this pie chart, if I had 180 skittles, how many would be red?
