Unit 4 Frameworks
The following tasks in Unit 4 are related to this released item:
If the Shoe Fits!(Learning Task)TV / Test Grades (Learning Task)Spaghetti Regression (Learning Task)
Purpose of Tasks
• Problem-Based-Learning--Check out Dan Meyer, Robert Kaplinksy’s websites
• Provide several entry points to the standards.
• Teachers should review all tasks in a given unit to determine which tasks would be appropriate for their students. Tasks can be adapted to fit the needs or your classroom. Most standards are covered by various tasks
Goals of Unit Revisions
• More user-friendly• Provide teachers with task summaries• Give teachers tools necessary to quickly
analyze tasks• Provide tasks from different sources
Updates to Unit Frameworks
TASK TABLE• Outlines the
tasks by type, content and standard.
• Provides suggested times
• Hyperlinks to PDFs and Word Docsv
Updates to Unit Frameworks
Unit 4
• Task primarily address:– Representing data using dot plots, box plots, scatter
plots and frequency graphs– Interpret differences in shape, center, and spread in
the context of data sets accounting for outliers– Understand correlation as the degree of fit between
two variables– Find a linear function (model) for a scatter plot– Use residuals to informally assess the fit of a
function
Represent & Interpret Data
Task• Math Class• Basketball Star• Representing Data 1: Using
Frequency Graphs (FAL)• BMI Calculations (CTE)• Representing Data 2: Using
Box Plots (FAL)• Public Opinion and Leisure
Time
Basic Content Addressed• Represent data using dot
plots, box plots and histograms
• Compare and interpret center, shape and spread of two or more data sets
• Use frequencies and relative frequencies to compare data sets
The Basketball Star Task
• More user friendly• Questions were changed
and rearranged to help students explore and interpret dot plots, box plots and histograms
BMI Calculations (CTE)Career and Technical Education Task
Task Coversheet with Standards Addressed The Task Worksheet
BMI Calculations (CTE)
Possible Solutions Extension Activity
Public Opinion and Leisure Time Task
• Combined Public Opinion and Leisure Time Task together
• Expanded Leisure Time task by adding questions for the students to answer about the frequency table and conditional frequency table
• Deleted Jana’s relative frequency table about basketball
Relationships Between Data & Finding Linear Models
Task• If the Shoe Fits!• Spaghetti Regression• Devising a Measure for
Correlation (FAL)• TV/Test Grades• Equal Salaries for Equal
Work
Basic Content Addressed• Represent and interpret
data on a scatter plot• Understand correlation as
the degree of fit between two variables
• Finding a line of best fit or regression line for the data
• Assess the fit of a function by plotting and analyzing residuals
MARS FAL
• Designed by the shell center• Intended as student-driven, teacher-facilitated
lessons that build conceptual understanding
