45-45-90 Triangles
To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.
Rise Over Run! Let’s Have Fun!
Students will collaboratively practice identifying and graphing slope and y-intercept.
Equations in the Real World
Students will create and solve equations with variables on one side before comparing the equation with another to determine at what rate they will be equal.
Working with Literal Equations
The lesson will provide a conceptual basis for illustrating the parallelism between solving multi-step equations and translating literal equations into solutions for specified variables.

Four Representations of Linear Relationships
Given one representation of a linear relationship, students will create a poster displaying the other three representations of linear relationships.
Solving Rational Equations
Students will discuss and formulate an equation to solve an engaging real-world problem. They will use manipulatives to describe how to find the common denominator they need to solve the equation. They will break up into groups and solve for a more complicated problem.

Concert Trip to Red Rocks Amphitheatre in Colorado
Students will evaluate and interpret data from both tabular and graphical forms to create a linear equation in either the form of direct variation (y=kx) or slope-intercept form (y = mx + b). Students will then use their findings to interpret the meaning of both slope and y-intercept using a real-world relationship in word form.
No Interest If Paid in Full: How Much Do I Owe?
Students will write a linear equation from a real-world situation, identify the components of the equation, and interpret their meanings in the problem’s context.

Proving Triangles Congruent Using the Side-Side-Side and Side-Angle-Side Postulates
Students will prove: Two triangles are congruent using the Side-Side-Side (SSS) and Side-Angle-Side (SAS) postulates.

Which One Doesn't Belong? Proportional vs Non-Proportional Relationships
Students will make connections as they examine proportional and non-proportional relationships represented in functions including tables, equations, graphs, and verbal descriptions and think critically to determine which one does not belong in a set and why.

Can We Get There?
Students will calculate the rate of change and y-intercept from a real-world problem represented in a graph, a table, and/or an equation. They will then display and present their findings to the class.
Students working in their group
Balancing Act
Given a prompt, students will solve a multi-step equation using concrete and/or pictorial models.
Teacher Posing the Task
Breakout with Linear Relationships
Through a collaborative breakout station format, students will access prior knowledge to develop a deeper understanding of the relationships of slope through proportional relationships represented by unit rate and linear non-proportional relationships. A variety of representations will be practiced through scenarios, tables, graphs, and equations.
Identifying Key Features of Quadratic Functions
The students will be able to graph quadratic functions using key attributes of quadratic equations.
Square Root Regression
This lesson is a student discovery lesson that culminates in square root regression with technology. Students will use their study of inverses, the relationship between quadratic and square root functions, their previous knowledge of regression, and determine how to find the square root regression of real-world data.
