Solving Linear Equations with the Yo-Yo Problem
Students explore linear patterns, write a pattern in symbolic form, and
solve linear equations using algebra tiles, symbolic manipulation, and
the graphing calculator.
Chicago Public Schools
This is a structured lesson plan that provides strategies for teaching,
examples, worksheets, and assessments. (Day 33-37, 44, 62, several days
of lessons that cover several bullets)
Purple Math
This is an
online tutorial on how to solve linear equations.
Purple Math- How to solve radical equations
This online
lesson is easily adaptable to a classroom lesson, complete with example
problems. Look under Beginning Algebra topics in the index and
choose Solving Radical Equations.
Solving Literal Equations
A lesson plan including a lesson, practice and teacher resources for
solving literal equations.
Direct Variation
A lesson plan including a lesson, practice and teacher resources.
Direct and Partial Variations
A lesson plan for identifying direct variations and solving direct
variation problems.
Rearranging
Formulas from Geometry for different variables
This is an
online lesson that guides students through solving literal equations.
Discovering the Linear Relationship between Celsius and
Fahrenheit
This
lesson is based on real-world data from the SR-71 Blackbird, a famous
spy plane. It also relates Fahrenheit and Celsius temperature scales.
Students may use the TI-83.
Battery Life on NASA Vehicles
This lesson shows the linear model for battery depletion. It is a piecewise
linear model graphing power usage by a remote controlled airplane. (A
little advanced, but perfectly usable)
Plugging into the Best Price
Students will use a graphing calculator and
the instructional activity sheets to explore the parameters of a linear
function and the significance of the slope and y-intercept. This
knowledge will be used to interpret a linear relationship between the
cost and time of performing a job.
Squares in the Light
This lesson is designed for students to investigate the relationship
between the length of the side of a square and its distance from the
light source. A 2 cm square is cut from a 3" by 5" card and placed on an
overhead projector. The students will then measure the side of the
square projected on the overhead screen and the distance from the screen
to the projector. This data will be tabulated, graphed, and analyzed.
Hit Me If You Can!
This lesson is designed to
help students learn to use the CBL and the motion detector. Using the
CBL, TI-82 and motion detector, students will see that the speed and
direction of their own body over time creates a different slope line.
This can lead to discussions of linear equations, specifically positive,
negative, and zero slopes. After this lesson, students should have a
better idea of slope and y-intercept.
Chicago Public Schools
This is a structured lesson plan that provides strategies for teaching,
examples, worksheets, and assessments. Instruction on the TI-82/83 is
provided, but the use of calculators is not essential. (Day 71-72, 80)
Mystery Liquids
The Mystery Liquids lesson is a data
analysis lab in which students gather mass and
volume data for two mystery liquids, oil and water, and then use the
data to explore
linear functions. Connections to science are an important part of this
algebra lesson,
which deals with density. Active learning and communication are aspects
of the
lesson that are modeled for teachers. Students discuss the physical
meaning of the
slopes and y-intercepts of the various lines they have created from
their scatterplots.
Purple Math
This is an
online tutorial that guides students through graphing the solutions to
linear inequalities. It extends to quadratic inequalities.
SOS Math
This is a lesson on absolute value and solving absolute value equations
and inequalities. It shows how to use interval notation and the number
line to show the solution set of absolute value inequalities.
Pennies, Pressure, Temperature, and Light
The major goal of this lesson is to collect data from a variety of
experiments, and then determine what type of model best fits the data,
and explain why.
Students will explore a variety of relationships using pennies,
pressure, temperature, light, and pendulums to determine the algebraic
equation that best represents the pattern modeled by the variables
involved in each situation.
Stressed to the Breaking Point
Students will explore the relationship between the amount of weight that
can be supported by a spaghetti bridge, the thickness of the bridge, and
the length of the bridge to determine the algebraic
equation that best represents that pattern modeled by the three
variables.
