## Scale City: Greetings from Sky-Vue Drive-In

Icon:

Greetings from Sky-Vue Drive-In takes students on a tour through the history of drive-in theaters and a visit to one that's still open and thriving in Winchester, Kentucky. Looking at shadows through the drive-in movie projector introduces the relationship of a shadow's size to its distance from the light source.

## Analyzing its Geometry and Energy Efficiency | Treasures of New York: "Hearst Tower"

Icon:

Students solve a real-world mathematical problem involving the area of a triangle and learn about how energy conservation is applied to architectural design using video from Treasures of New York: Hearst Tower. Utilizing text-dependent discussion questions and classroom activities called “teaching tips,” students have an opportunity to take a deep dive into mathematics, STEM content and the arts.

## Scale City | Scaling Up Rectangles in the Real World

Icon:

In this video, students explore Depression-era post office murals and modern outdoor murals to learn how artists use proportional reasoning and measurement to create large-scale paintings. The video ends with the question, "How do artists use math to create large-scale paintings?" In the accompanying classroom activity, students create a group mural by using a predetermined scale factor to increase the size of a rectangular print or drawing.

## Geometry and Classification of 2D Figures: Bianca Busts a Move

Icon:

In this video from Cyberchase, Bianca breaks her friend’s tabletop when she’s practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying classroom activity helps students advance their understanding of perimeter and area by creating their own tabletop designs. This resource is part of the Math at the Core: Middle School Collection.

## Pythagorean Theorem in Kapa Design

Icon:

Listen to a master quilt maker discuss the relationship between art and mathematics as she demonstrates how the Pythagorean theorem is an important part of the pattern design process in this video from the Center for Asian American Media. This resource is part of the Math at the Core: Middle School Collection.

## Shoshone Parfleche | Wyoming's Native Americans

Icon:

Students will gain an understanding of the Shoshone tribe while learning about the Shoshone Parfleche from the WyomingPBS video.

## Thinkport | Folding Sculptures

Icon:

Watch sculptor Mary Ann Mears demonstrate how she uses scale modeling and other mathematics in creating geometric sculptures in this video from MPT. In the accompanying classroom activity, students design a scale model of a sculpture for the school grounds. They calculate the height and width that the full-size sculpture would be. To get the most from this lesson, students should have some exposure to scale models and be comfortable using a protractor to measure and draw angles. For a longer self-paced student tutorial using this media, see "A Focus on Surface Area and Scale Drawings" on Thinkport from Maryland Public Television.

## Geometry and Spatial Relations: It's a Perfect Fit (Part 2)

Icon:

In this resource group, teachers can focus on the topic of geometry and spatial relations by having students identify and describe numerical relationships found among pattern block shapes. Students learn to join pattern block pieces together to cover a region. This resource group is part of the Mathline Elementary School Math Project.

## Between the Lions - Letter Bit: Shapes

Icon:

Watch real kids introduce different shapes from their everyday lives. This video segment from Between the Lions focuses on recognizing and naming some of the shapes that can be found around you in your everyday life.

## Blossom and Snappy Build Scale Models | Count On It!

Icon:

Blossom and Snappy learn about scale models and how they are used in the design and construction of buildings. They visit an architectural firm, a construction site, Clark Atlanta University Art Gallery, and Clark Atlanta University Science Center. They learn how to build their own scale model of a house.

## Thinkport | Proportional Relationships and Slope: Part 2

Icon:

Explore the role that proportions play in the design of cakes composed of several tiers in this video from MPT. In the accompanying classroom activity, students watch the video. Next, they examine photographs of tiered cakes, taking measurements to determine if the tiers are in proportion. They conclude by reflecting on the cake photographs and considering why the cake designer maintains that cakes in proportion are pleasing to the eye. To get the most from the lesson, students should have some familiarity with ratio and related tables of values. For a longer self-paced student tutorial using this media, see "Proportional Relationships and Slope" on Thinkport from Maryland Public Television.

## Thinkport | Mapping Sculptures

Icon:

In this video from MPT, learn how sculptor Mary Ann Mears uses angle measurement and geometric relationships when determining angles in scale models. In the accompanying classroom activity, students apply what they learn in the video as they solve problems in which they are given clues about two of the angles in a triangle and must determine the third. Clues involve measurements of interior and exterior angles in the triangle. To get the most from the lesson, students should be familiar with the concept of scale models. For a longer self-paced student tutorial using this media, see "Mapping Out Sculptures" on Thinkport from Maryland Public Television.
