This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.

In this problem, students are given a picture of two triangles that appear to be similar, but whose similarity cannot be proven without further information. Asking students to provide a sequence of similarity transformations that maps one triangle to the other focuses them on the work of standard G-SRT.2, using the definition of similarity in terms of similarity transformations.

This video segment adapted from NOVA features a variety of scientific perspectives on the age old question, "Are we alone in the universe?" Animations make vivid the improbability that we could intercept a radio wave signaling extra terrestrial intelligence.

Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!

Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying algebraic expressions. Use the game screen to test your multiplication and factoring skills!

This activity reinforces the concepts of area and perimeter and their independent relationship. Students analyze and compose shapes made from unit squares that satisfy area and perimeter specifications. Ideas for implementation, extension and support are included along with printable sheets and shape cards.

This activity is intended to assess your 3rd grade students' ability to find area and perimeter of rectangles and squares. Students will be creating a robot using Google Drawing. They will then find the area and perimeter of each piece of the robot. Once they have found the area and perimeter for each shape in their robot, students will calculate the total area and perimeter of the robot. Photo by Eric Krull on Unsplash

This web resource is an interactive way to help students visually understand why the area of a circle is r x r x pi.

This short video and interactive assessment activity is designed to teach third graders an overview of area of squares and rectangles - word problems.

Open Middle provides math problems that have a closed beginning, a closed end, and an open middle. This means that there are multiple ways to approach and ultimately solve the problems. Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding.

This is a lesson intended for 6th-grade mathematics on deriving the formula for the area of a triangle based upon prior knowledge of parallelograms. This lesson aligns with Utah Core Standards 6.G.1 and 6.G.3. This lesson is intended to be taught in a face-to-face setting and will take approximately 35-45 minutes.
