6th Grade MathFocus 2: Rates, including
percentsStandards: 6.RP.2, 6.RP.3b, 6.RP.3c
Resource: Connected Math Program 2Bits and Pieces I, Investigation 4.2
Introduce percents as a part-whole relationship where the whole is not out of 100 but scaled to be “out of 100” (4.1)
Use fraction partitioning and fraction benchmarks to make sense of percents (4.1) Develop strategies, including percents, to use in comparisons where the whole is less than 100 (4.2) Understand that comparing situations with different numbers of trials is difficult unless we use
percents or some other form of equivalent representation (4.2) Work with situations where the whole is sometimes greater than 100 and sometimes less than 100
(4.3) Develop connections between fractions, decimals, and percents (4.3) Develop strategies for expressing data in percent form (4.3) Relate fractions, decimals, and percents (4.4) To move from percents to other representations and from other representations to percents (4.4)
Bits and Pieces 1- Investigation 4: Working with Percents
Mathematical Learning and Problem-Solving Goals
Students will be able to work with percents by understanding and completing the
following:
1. Develop strategies, including percents, to use in comparisons where the whole is less than 100
2. Understand that comparing situations with different numbers of trials is difficult unless we use percents or some other form of equivalent representation
Bits and Pieces 1, Investigation 4.2Mathematical Learning Targets
Getting Ready for Problem 4.2
Draw a Percent Bar for EACH player in Part A in your workbook
Write down the RAW data and percent scale on each Percent Bar
Consider making equivalent fractions to help you scale the raw data to the correct percentThis means you might need to reduce or increase the raw data to
equal a whole of 100
If you can’t make equivalent fractions, what operation could you use to scale it to 100?
Getting Ready for Part A
Problem 4.2, Part A
TEACHER ONLY! Guide to Class Observation
What is in the problem or the numbers that made you decide to find Emily’s percentage one way and Angela’s another way?
Will the approach you used for Angela work for Cristina and Emily too?
Which approaches appear to work for all the cases in Questions A and B and which ones do not?
Why might this be the case?
Problem 4.2, Part AHave you thought about?

Lesson Summary
Students will be able to work with percents by understanding and completing the
following:
1. What strategy did you use to make comparisons when the whole was less than 100?
2. Explain how using percents or other form of equivalent representation makes it easier to compare situations.
