What are we learning?

Students will be solving multi-step linear and absolute value equations. 

What to expect in this unit?

This unit will build on what students learned in Math 8 and will extend their understanding of equations as they apply their ability to solve linear equations to absolute value equations. The unit will consist of formative and summative assessments. 

Why does this unit matter?

This unit is foundational to all future units this school year, in particular the first half of the year as we focus on linear functions.

What are we learning?

Students will be solving multi-step linear and absolute value inequalities. 

What to expect in this unit?

The unit will consist of formative and summative assessments including a performance task which will allow them to choose a problem and create a video explaining how to solve the inequality. This year we have IXL as a resource to support student learning. Moving forward, students will be provided with IXL topics that align with what they are learning in each unit. Some topics will be assigned as homework and others are for students to complete if they need extra practice on a particular topic. 

Why does this unit matter?

This unit will continue to build upon students' understanding of inverse operations. They will also be introduced to interval notation which will be used as students explore characteristics of functions through the year.

What are we learning?

Students will be writing equations for linear functions in slope-intercept form, standard form, and point-slope form. Students will also be analyzing lines of best fit and learning how to use a graphing calculator to better analyze data. 

What to expect in this unit?

The unit will consist of formative and summative assessments including a performance task which will allow them to create a picture, and write the equations of the lines in the their picture. This year we have IXL as a resource to support student learning. Moving forward, students will be provided with IXL topics that align with what they are learning in each unit. Some topics will be assigned as homework and others are for students to complete if they need extra practice on a particular topic. 

Why does this unit matter?

This unit will expose students' to the graphing calculator and how they can use technology to analyze data. While this will provide an introduction to the graphing calculator, we will continue building upon their ability to use it in future units. 

What are we learning?

Students will be solving systems of linear equations by graphing, substitution, elimination, and using the graphing calculator. Students will also learn how to graph linear inequalities and solve systems of linear inequalities by graphing. This will be the last unit that focuses on linear functions since after winter break, we will begin exploring various nonlinear functions.

What to expect in this unit?

The unit will consist of formative and summative assessments including a performance task which they will create a scenario that can be solved using a system of equations and a scenario that can be solving using a system of inequalities. Students will be provided with IXL topics that align with what they are learning in each unit. Some topics will be assigned as homework and others are for students to complete if they need extra practice on a particular topic. 

Why does this unit matter?

Systems of equations and inequalities can be used to model real-life situations. For example, they can be used to represent different the pricing for different companies to then determine when each one would be the better deal.

What are we learning?

Students will be focused on simplifying exponential expressions using various properties of exponents. Students will also be writing and graphing exponential functions. They will extend their knowledge of exponential functions to write and use exponential growth and decay and compound interest. functions

What to expect in this unit?

The unit will consist of formative and summative assessments including a performance task which will involve using exponential functions in real-world scenarios. Students will be provided with IXL topics that align with what they are learning in each unit. Some topics will be assigned as homework and others are for students to complete if they need extra practice on a particular topic. 

Why does this unit matter?

Exponential functions can be used to model real-life situations. For example, they can be used to represent the growth of viruses over time.

What are we learning?

Students will be focused on graphing quadratic functions in standard form, vertex form, and intercept form. Students will also be using their graphing calculator to graph quadratic functions and find key features of the graph. We will wrap up the unit by comparing linear, exponential, and quadratic functions.

What to expect in this unit?

The unit will consist of formative and summative assessments including a performance task which will involve students taking a picture of a parabola in real life and creating a quadratic equation to model the object. Students will be provided with IXL topics that align with what they are learning in each unit. Some topics will be assigned as homework and others are for students to complete if they need extra practice on a particular topic. 

Why does this unit matter?

Quadratic functions can be used to model real-life situations.  Students will be working with the vertical motion model.
