Lesson Purpose

This lesson is designed to enhance student understanding of the following mathematical skills:

Measurement and Spatial Reasoning: students will make frequent use of a protractor in the construction of appropriately-sized pie charts in the representation of data.
Numeracy: students will understand percent of a whole as a visual model. They will be able to compare a given percent to a benchmark percent value (25%, 33%, 50%, 66%, 75%) in order to have a sense of accuracy and intuitive meaning. Students will develop an ability to connect different representations of the same data, and be able to represent data in multiple forms to better understand percent/proportional reasoning.
Procedural Fluency: students will increase their procedural fluency, which is one of the components of rigor, by repeatedly using the standard algorithm for computing percent of a whole
 

Additionally, this lesson is designed to enhance student understanding of the following mathematical concepts/content areas:

Percent: students will be asked to make computations with percent as an input or output
Precise Representation of Data: students will construct accurate pie-charts that describe raw data
Proportional Reasoning: students will apply percent concepts toward their overall understanding and development of proportional reasoning
The mathematical skills and content in this lesson has significance in the workforce and in high stakes exams such as the GED® exam, COMPASS®, and KYOTE®.

Pre-requisite Knowledge: Ideally, students will already have some experience calculating percent; this should not be the first lesson in a unit on percent for students.

CCR Focus Standards

Number and Ratios - Level D

• 6.RP.3c

  Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.

• 6.RP.3d

  Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
