Measurement and Data

Center and Spread

Students will recognize that the mean and standard deviation (SD) and the median and interquartile range (IQR) are two ways to measure center and spread.

Tootsie Pops & Hand Span

Students will collect data, find the linear regression model of the data, and address aspects of the data that affect regression.

Conditional Probability

Students will investigate the difference between the probability of an outcome and the conditional probability of an outcome.

Contingency Tables and Chi Square

Students will investigate chi-square as an indication of whether two variables in a population are independent or associated.

Statistics: Tossing Coins

Students will use a simulation to find the experimental probability of independent events, tossing two coins. Then they will compare it to the theoretical probability.

Birthday Problem

Students will compute the probability that two people in a group will share a common birthday.

Probability of Repeated Independent Events

Students will investigate probability by simulating tossing a coin three times.

Airport Impact Study

Students will perform a simulation to measure the sound intensity at different distances from the source of the noise, and then use the data to develop an inverse variation model.

Students will recognize that the sum of two central angles that combine to make a circle is 360°.

Circles: Angles and Arcs

Students will explore the relationships between angles and the arcs formed when they intersect circles different ways.

Creating a Midpoint Quadrilateral

Students will focus on the idea that the midpoints of any quadrilateral form a parallelogram. Area relationships will also be investigated.

Similar Figures

Students will observe ratios of pairs of sides in geometric shape to discover when they are similar.

Corresponding Parts of Congruent Triangles

Students will identify corresponding parts of congruent triangles and use appropriate notation to describe two congruent triangles.

Nested Similar Triangles

Students will identify conditions for similar triangles that are nested and share a common angle.

Exploring Perpendicular and Angle Bisectors

Students will define and investigate the properties of both a perpendicular bisector and an angle bisector.

Side-Side-Angle: The Ambiguous Case

Students will identify the conditions necessary to determine a unique triangle when given two sides and a non-included angle.

Transformations with Lists

Students will use lists to investigate transformations of geometric figures.

Transformations: Rotations

Students will explore rotations and geometric figures.

Exploring Transformations

Students will investigate transformations of geometric figures.

Points, Lines and Planes

In this lesson, students will identify, recognize and discuss many properties of lines and planes.

Expressions, Equations and Functions

Extraneous Solutions

Students will discover solutions of radical equations and investigate extraneous solutions. Students will find a solution algebraically and use technology to graphically find them.

Linear-Quadratic Inequalities

Students will use sliders to control the intersection of a quadratic and a linear inequality.

Zeros of a Quadratic Function

Students will use sliders to change the linear factors of a quadratic function. Students will connect the zeros of the quadratic function to the zeroes of the linear factors.

Vertex and Factored Forms of the Quadratic Function

Students will be able to identify and justify the effect of changing the parameters of a quadratic function in vertex form and factored form.

Quadratic Functions and Stopping Distance

Students will analyze and compare data for stopping distances for 3 conditions: normal conditions, talking on a cell phone, and a wet road.

Finite Differences

Students will investigate into the set of differences for linear, quadratic, and cubic functions.

Linear Inequalities in two Variables

Students will discover the basics of graphing a linear inequality.

Applications of Linear Systems

Students will use a system of linear inequalities to solve a problem a real world problem about parking cars and buses.

Solving Systems by Graphing

Students will compare a linear and an exponential relationship using both a spreadsheet and scatter plots.

Comparing Linear and Exponential Functions

Students will compare a linear and an exponential relationship using both a spreadsheet and scatter plots.

Trains in Motion

Students will visualize a solution to a system of equations and will explore a system that intersects in one point and identify the ordered pair that represents the solution.

How Many Solutions to the System?

Students will translate and rotate a line to visualize that a system of equations can have a unique solution, infinitely many solutions, or no solution.

Multiple Representations

Students will explore information represented in tables, graphs, and symbols to interpret the meaning of slope and intercepts in the context of a real world situation.

This lesson involves identifying a set of x-values in both symbols and words, identifying the set of x-values used in generating the function as the domain of the function, and identifying the set of y-values used in generating the function as the range of the function.
