Lesson Plan

 

Standard 

6NSO.C13  Calculate given percentages of quantities and solve problems involving discounts at sales, interest earned and tips

6.DASP.2. Construct circle graphs using ratios, proportions, and percentages. 

Aim/Objective:

Key Points

·         Create circle graphs

·         Circle graphs are appropriate for surveys or other data that doesn’t overlap where the total represents 100%

·         To make a circle graph – change all numbers into percentages by finding the part of the whole each section represents

Assessment:

Students create a circle graph:

 

After lunch, 40 students had a choice of bread pudding, vanilla pudding or chocolate pudding for dessert. 

  • 4 students chose bread pudding
  • 20 students chose vanilla pudding
  • 16 students chose chocolate pudding

 

A What is the percentage of students who chose each type of pudding

 

B  Label the circle graph with titles and percentages

 

 


Lesson

Notes:

·         As we know from yesterday, circle graphs show different parts of a whole (100%). 

·         When creating a circle graph, we should follow these steps:

o   Determine if the data is “suitable” for a circle graph.  Is there a whole for the data?

 

Which of the following data sets are “suitable” for a circle graph?

o   Calculate Percentages – determine what the whole is by adding all of the parts together.  Then figure out the percents by dividing the part for each category by the whole.

o   Draw the Graph – draw a circle and divide the circle into parts.  Use a 100th disc to help you split the parts accurately

 

 

 

o   Title and Label the Graph – give the graph and appropriate title and label each section with the name and percentage.
