ACTIONS
Goals and Objectives- Students will:
Connections – The following Core
Content requirements will be addressed:
·
MA-H-4.3.1 Students will write and solve linear
equations describing real-world situations. By analyzing supply and demand data in table
form, students will plot points, find equations for supply and demand, and use
these to find equilibrium points.
·
MA-H-4.3.2 Students will understand how formulas,
tables, graphs, and equations of functions relate to each other. This lesson will help students understand the
connections between verbal, graphical, tabular, and algebraic representations
of the same set of data. By discussing
factors which affect supply and demand, students will also recognize the
strengths and weaknesses of each form for particular objectives.
·
MA-H-3.3.4 Students will use data and curve of
best fit to make and defend predictions.
Students will apply a linear curve of best fit to a set of data points,
and use the equation of this line to predict outcomes of supply/demand scenarios.
·
MA-H-4.3.5 Students will show how equations and
graphs are models of the relationship between two real-world quantities. Small-group and whole-class discussions will
focus on the many factors which affect supply and demand in the real world. Students will gain an understanding of the
difficulty in finding an exact curve to represent a complex supply and demand
situation, and will recognize that curves of best fit can be used to make
valuable predictions in business.
Context - The focus of this unit is
finding, analyzing, and graphing linear equations. This lesson provides students with an
opportunity to apply these concepts to real-world business situations. This lesson will also help students recognize
that the same set of data can be represented in various ways, and that each of
these ways has its own strengths and weaknesses. After this lesson students will have a deeper
understanding of the relationship between independent and dependent variables
by examining this relationship in the context of real-life situations.
Resources - Students will use a set
of three activity sheets which can be printed from the curriculum
page for this lesson. They will use
a straightedge for connecting data points, and a graphing calculator for
finding curves of best fit. Transparencies
of the activity sheets will be used during in-class discussions.
Procedures - Students will work in
small groups of 3 or 4 during the first period of this lesson to find supply
and demand equations for a given set of data points. Using these graphs, they will then answer a
set of questions which require interpretation of the information. Students’ prior knowledge of how to find a
linear equation using two data points will be instrumental during this group
activity. Class discussions following
this activity will be used to strengthen understanding of the real-world
implications of the material, as well as to gauge individual progress. Students will work in assigned pairs to
complete the second day’s activity.
Student Assessment - Formative assessment
will be made by verbally quizzing students during the group activities, and by
whole-class discussion following the activity.
Summative assessment will be made in three parts. Each student will receive a grade for the
group activity from day 1, the group activity from Day 2, and an individual
grade for the homework assignment due at the beginning of day 2. A rubric will be used to formalize the
performance criteria for these summative assessments. The rubric can be found on the assessment page of this site.
