Below you will find tools (blog, class presentations, videos, websites) to enhance your understanding of Chapter 11 concepts. The SMARTBoard lessons that are presented in class are here in PDF format. Please keep in mind that these files will not be interactive like the class presentations due to the PDF format.

This link takes you to the Educanon site where you will have to sign in to view the videos this week. Videos that are posted for this week are categorized by due date now. A list of the videos posted so far this week are listed below:

*Area of a Trapezoid (about 3 minutes)

*Area of Circles & Circumference

*All about Circles Music Video (less than 2 minutes)

*3D Shapes and their Nets (about 2 minutes)

This file contains 12 composite figures to practice calculating the area. The answer key is provided as the last page in the file so that you can check your progress!

Interactivate is an online tool where you can explore how changing the dimensions of rectangular prisms or triangular prisms changes the surface area and volume. There is also an option to practice calculating the surface area and volume of prisms. This tool is a GREAT visual for 3D prisms!

You will have to print this puzzle in order to play at home. The current display is the answer key! The puzzle reviews calculating the volume of prisms and cylinders.

This file contains 12 posters where you can practice calculating the area of 2D figures, classifying 3D shapes, drawing 3D figures, and calculating the volume of 3D figures. The answer key is included as the last page. Please use to prepare for the unit test.

Please use this review worksheet to help you prepare for the Area and Volume test!

This interactive site reviews circle concepts and also provides real-world examples for additional practice! Make sure to click "Intro", "Investigation", and "Problems".
