create a circle graph

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?

 Feeding Time for Pets Night only 4% Morning Only 6% Morning & Night 42% Anytime 48% Total 100%

 Day of Week Temperature Monday 75° Tuesday 68° Wednesday 65° Thursday 85° Friday 92°

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.

Guided Pracice

Mrs. Jones asked her 5th grade students how many siblings each student in her class has.  The results are below in the table.

 Number of Siblings Number of Students 0 siblings 3 1 sibling 15 2 siblings 9 3 siblings 2 More than 3 siblings 1

1.      Is this data suitable for a circle graph?

2.      Create percentages for the categories above

 Number of Siblings Number of Students Fraction Percent 0 siblings 3 3/30 10% 1 sibling 15 15/30 50% 2 siblings 9 9/30 30% 3 siblings 2 2/30 »7% More than 3 siblings 1 1/30 »3% Total 30 30/30 100%

Studnets use given 100 disc to create a circle graph based on the information from above.
