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!

These guided notes help students understand the concept of geometric dilation and leads them though a look at what happens when negative and fractional scale factors are used to transform a figure on a coordinate plane.

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.

This bundle includes includes guided notes, a worksheet, and a group activity all related to determining if a function is linear, exponential, or quadratic.

These guided notes lead students though creating and graphing translations in geometry. They then practice discerning the rules and using rules to create transformations on a coordinate plane.

These notes cover the basics of graphing transformations on a coordinate plane. Students are refreshed on set up of a four quadrant graph with definition bank and visual example of translation, reflection, rotation and dilation.

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.

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.

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.

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.
