Students are required to read dot-plots, histograms, and box and whisker plots to come to conclusions about data based on the given information. They must assess if they can truly know certain facts given the limitations of each form of data display.

These notes are designed to help students connect independent and dependent variables to domain and range though graphs. They will also identify graphs as discrete or continuous.

These notes and activity page are designed to help students look at data and determine if it has a correlation and if that correlation is positive or negative. A great time saving alternative if there is not enough time for students to collect their own height and shoe size data. Can be made more personal after this introduction to help students develop their own possible correlations and gather data to back up their thinking!

This quick guided notes and practice page helps students identify slope by computing the constant ratio of change in y over change in x. They must also visualize their data by plotting the example table on a coordinate plane to see the linear relationship.

Students will be walked though how to use the Ti-83 Graphing Calculator to find the line of best fit between two sets of data. They will then use that equation to make predictions within the data set and use their predictions to calculate residual.

These notes help students to use first and second differences to determine if a given relationship is a linear, exponential, or quadratic function.

These notes transition students from the concept of slope to a proportional constant found in a directly varying relationship. These notes pair well with my linear, proportional, or neither worksheet.

Students must analyze a table to determine if it has a linear relationship (constant rate of change) and if so, if the relationship is also proportional and what the proportional constant is.

These notes specifically guide students though the process of taking two ordered pairs and converting them from point slope, to slope intercept, and finally into standard form. There are two 'I do' teacher examples followed by two examples for students to work on in groups. It took my advanced algebra students approximately 35 minutes to follow along and productively struggle though examples.

This sorting activity requires groups to read four real world situations and match a linear function rule, mathematical, and realistic domain and range for each scenario. They are then asked to defend the reason they picked the function rule they did and compare their answers as a class.

The goal of this short exercise is for students to start to connect that a larger standard deviation means that data is more spread out, even if it has the same mean and median as another set of data.

Student will practice being able to determine if a given linear relationship is proportional or not in graph or table form. They will be asked to find the proportional constant (which we called m instead of k to tie in to slope-intercept form) as well as use given proportional equation to solve for missing quantities.

This worksheet uses function notation to develop rules for real world scenarios. Students can be guided though first part and use the second for independent or group work, or whole sheet can be done for continued reinforcement.

These notes are designed to help students recognize linear, quadratic, and exponential functions based on tables and graphs.

This activity has two different versions. Both require students to show how the line made by a set of ordered pairs has been represented in three different ways: in a point slope equation, slope intercept equation, and standard form equation. In the first option, the four matching cards are in order and students must show their work for how they got form one to the next. The second option the sets of 4 are jumbled and students must cut them out and match them together.

Students must use speed = distance/time formula to solve for whichever part of the rate equation is missing. Their answers will reveal the solution to a riddle at the bottom of the page.

Students have 20 sequences that must be sorted in to linear (proportional and non-proportional), quadratic, and exponential. There are the same number of cards for each category.

This is a very brief exit pass or bell ringer designed to see how well students are progressing making growth/decay factors based on a rate of change, as well as solving word problems.

Students will learn the basics of how to write a function using recursive function notation and practice writing geometric and arithmetic sequences. They will also explore how recursive functions can be used to write the Fibonacci sequence.

This activity is set up for groups but can be done individually. Students are given a scenario involving a business and must make a linear function rule to represent the situation. They are then asked to analyze the impact of real world constraints on domain and range and create a graph to illustrate their analysis.
