###
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.

###
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.**

###
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.**

###
Wrap It Up! Lateral Area and Surface Area of Prisms

Students will be given a net to calculate how much material it would take to cover the surface.

###
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.

###
Diagramming Dinosaurs

Students will use a verbal representation to explore a constant rate of change in the size of dinosaurs over a period of time and represent their data by graphing.

###
Compound Probability: Independent vs. Dependent Events

Students will review steps for solving compound probability problems through an activity involving doughnuts. Students will then determine the difference between independent and dependent events through compound probability task cards. To encourage students to work through their struggle, students will rate themselves on a scale measuring effort and achievement at the end of the lesson.

Comparing Box Plots and Dot Plots

This lesson is a 90-minute lesson that can be delivered in one block or split into two 45 minute lessons. The first part of the lesson engages students in a notice/wonder activity that is designed to help students begin to question how data is represented in box plots and dot plots. The second part of the lesson is designed for students to compare data in box plots and dot plots and identify truths and untruths about the representations.
