Grade Level: 9th Grade Algebra I for 8th graders
Unit Name: Investigate Patterns of Association in Bivariate data
Unit Description: Interpret Categorical and Quantitative Data
Building on their earlier experiences with graphs and tables in Grades 6 and 7, students a routine of
exploring functional relationships algebraically, graphically, numerically in tables, and through verbal
descriptions.8.F.2 They explain correspondences between equations, verbal descriptions, tables, and
graphs (MP.1). Repeated reasoning about entries in tables or points on graphs results in equations for
functional relationships (MP.8). To develop flexibility in interpreting and translating among these various
representations, students compare functions in 2 different ways.

How can you use graphs, charts, and tables to make informed conclusion about data?
How are equations and graphs related?
What does it mean to say that two variables vary directly or inversely?
Primary Standards: (Needed for 8th PARCC Assessment):
8.SP.1 Construct and interpret scatter plots for bivariate measurement data to investigate
patterns of association between two quantities. Describe patterns such as clustering, outlier,
positive or negative association, linear solutions, and non-linear association.
8.SP.2 Know that straight lines are widely used to model relationship between 2 quantitative
variables. For a scatter plot informally fit a straight line as a model.
8.SP.3 Use the equation of a linear model to solve problems in the context of bivariate
measurement data, interpreting slope and intercept.
8.SP.4 Understand that patterns of association can also be seen in bivariate categorical data by
displaying frequencies and relative frequencies in a 2-way table. Construct and interpret a 2way table summarizing data on two categorical variables collected from the same subjects. Use
relative frequencies calculated for rows or columns to describe possible association between
two variables.
Secondary Standards:
7.SP.1 Understand that statistics can be used to gain information about a population by
examining a sample of the population; generalization about a population from a sample are
valid only if the sample is representative of that population.
7.SP.2 Use data from a random sample to draw inferences about a population with an unknown
characteristic of interest. Generate multiple samples (or simulated samples) of the same size to
gauge the variation in estimates or predictions.
7.SP.3 Informally assess the degree of visual overlap of two numerical data distributions with
similar variabilities, measuring the difference between the centers by expressing it as a multiple
of a measure of variability.
7.SP.4 Use measures of center and measures of variability for numerical data.

Depending on which cognitive skill a student is having difficulty, the following may occur:
1. Student may confer with teacher
2. A short diagnostic test is given to the student.
3. The diagnostic test is evaluated by student and teacher.
4. Based on the test results, the student may be assigned a resource, such as Ramp-up
pages, or mathops.com, or CME online practice to reteach and reinforce the difficult
skill.
According to WIDA Standards, English language learners benefit from:
Explicit instruction with regard to parts of expressions, equations and inequalities.
Explicit instruction with regard to the relationship between graphs or tables and the
equations and contexts they represent.

Technology
For Math Anxiety: Five minutes before an assessment, have students to write down all of their
thoughts about taking a math quiz or test. This journaling remains with the student
Use Khan Academy app on Ipads for tutorial
Use Khan Academy website w/ Safari for practice problems
Use Mathops.com for tutorial and practice
Use WileD- Math app on Ipads to practice solving one-step and two-step equations
Use CME online resource for vocabulary, lesson practice, or unit tests.
