Lesson Planet

#### Cell Phone Battery Life

How much battery is left? Well, that depends on the time. The resource presents a situation in which the percent of a cell phone battery left is a function of time the phone has been in use. Pupils interpret an expression and an equation...

Lesson Planet

#### Breakfast Drink Preference

Set the table for learning using a great resource. The resource has a group of high school and college pupils select their favorite breakfast drinks. Class members create a two-way frequency table to display the given data.

Lesson Planet

#### Arc Length and Radians

Relate the constant of proportionality to radians. Pupils use the fact that all circles are similar to show that the arc length subtended by an angle is proportional to the radius. The scholars use the shown relationship to verify the...

Lesson Planet

#### Airport Parking

How long will the domain allow for parking? Pupils interpret a graph of a parking fee structure. The scholars find the domain of the function and explain how to determine it.

Lesson Planet

#### 2D Rotations of Triangles

Where does the line of rotation need to be to get a cone? Pupils respond to three questions involving rotating a right triangle about different lines. The scholars describe the solid created along with providing details about its...

Lesson Planet

#### Car Wash

Find the domain of a discrete graph. Learners analyze a graph depicting the earnings and number of cars at a charity car wash. They then determine the domain and describe it.

Lesson Planet

#### Diagonals of a Rectangle

Coordinate the vertices of a rectangle. Pupils use the location of three vertices of a rectangle along the axis to find the coordinates of the fourth vertex. Using the vertices of the rectangle, scholars prove the diagonals are congruent...

Lesson Planet

#### Describe the Domain

Determine numerical representations for cupcakes and time. Given two scenarios, pupils determine a reasonable domain for numbers of cupcakes and time to run a race. The scholars develop a description of the domain including lower and...

Lesson Planet

#### Density

Does accuracy mean you must use all the possible digits? Provided with a density problem, pupils determine the level of accuracy to report the value. The assessment provides three values of varying numbers of digits for the learners to...

Lesson Planet

#### Definition of Parallel Lines

What does it take to be precise in creating a definition? Scholars demonstrate an understanding of parallel lines by drawing them. They develop a definition that contains enough information but does not have any unecessary criteria.

Lesson Planet

#### Define a Translation

Translate from action to a definition. Given a point and a directed line segment, learners conduct a transformation. The scholars record the steps they take while performing the transformation. The individuals develop a definition from...

Lesson Planet

#### Comparing Functions—Linear

Identify transformations of linear functions. Given the graph of the linear parent function, pupils compare the graphs of four other linear functions and determine how the graphs of each linear function relates to the graph of y = x.

Lesson Planet

#### Comparing Distributions

Pupils compare histograms of test scores of two data sets. The scholars describe any similarities and differences of the distributions, paying attention to shape, center, and spread. In the process, the learners determine which set of...

Lesson Planet

#### Compare Linear and Exponential Functions

What is the better pay rate? The resource presents a babysitting situation with two payment plans. Pupils must determine whether to choose the linear or the exponential plan based upon the number hours of babysitting.

Lesson Planet

#### College Costs

Scholars determine the percentage increase of college tuition for a decade based upon the equation given for a year. Pupils rewrite the exponential equation by changing the variable to reflect ten years instead of one.

Lesson Planet

#### Circles and Functions

Scholars analyze the graph of a circle to determine what portion they should remove to make the resulting graph a function. The pupils mark the section on the graph and explain why what is left is a function.
