###
Solving Equations and Inequalities

Students will be divided into four groups and work on their assigned task to become an expert. They will match vocabulary terms with definitions and examples, use the “Pass the Pen” strategy to create and solve equations or inequalities, or write a real-world problem for an equation given. The experts will then teach these concepts to their peers.

###
Finding Clues to Solve Equations and Inequalities

**Students will solve one variable two-step equations and inequalities using a variety of materials while working independently and collaboratively in learning stations.**

###
Express Yourself

Students determine which expression is a truth or a lie by generating equivalent expressions.

###
Keep Your Balance!

**Students are introduced to solving one-variable, one-step equations using addition and subtraction through models and hands-on activities. The students will learn the substitution method of checking answers.**

###
Perfecting Percents

Students will engage in an activity that allows them to explore the different parts of percents: part, whole, and percent, and develop conceptual understanding of percents through the Concrete, Representational, Abstract (CRA) method of instruction.

###
Perfectly Proportional Percents

Students will collaborate to explain verbally how to solve percent proportions and scaling while showing their thinking.

###
Exploring Number Sense

Students will use manipulatives and a number path to identify numbers one less than or more than a given number.

###
Using Theoretical and Experimental Probability to Make Predictions

Given an event to simulate, the student will use theoretical probabilities and experimental results to make predictions and decisions.

###
Strike a Pose

The students will solve two-step equations through modeling, expressing algebraically, and writing out the steps to their solutions.

###
Rational Number Stations

**Students will visit two different stations and work as a group to add, subtract, multiply, and divide rational numbers.**

###
Modeling and Solving Two-Step Equations

Students will use various materials to create models of two-step equations. Then, they will take an equation, create their own model, and solve for the variable from the model.

###
Volume of Triangular Prisms

Students will use hands-on manipulatives to discover the connection between the shape of the base and the height to determine the volume of a prism.

###
Area of Composite Figures

Student groups will work collaboratively using the appropriate formulas to find the area of simple figures and combine the area of each shape to find the area of composite figures in real-world situations.
