• ## Engaging Students in Technology and Engineering Projects

Learn how MOUSE is engaging middle and high school students in technology and engineering in this video from American Graduate Day 2013. Beginning in the middle school years, students can join the MOUSE Squad, which trains them to become technology experts in their schools. As 11th and 12th graders, students can start to design new technologies in the MOUSE Crops. After selecting a service-orientated theme, the MOUSE Corps members design, test, and refine technologies that benefit other people. Use the handout in the teacher's resources to help prepare for a technology or engineering partnership at your school.

• ## Games of the North: Data & Graphing

Learn about some of the events held at the Arctic Winter Games, an annual celebration of athletics and culture in the far northern latitudes, in this video from Center for Asian American Media. In the accompanying classroom activity, students use statistical tools, including histograms and box plots, to determine how event results have changed over time. This resource is part of the Math at the Core: Middle School Collection.

• ## Locating Points on the Cartesian Graph

In this interactive, students use clues and logic to plot the location of aquatic animals on a Cartesian graph that represents the four cardinal directions. The three riddles in the interactive, including one that requires students to understand rate, have randomized values so that students can practice placing points at different locations on the graph. The accompanying classroom activity provides students with a review of locating points on a Cartesian graph. A response sheet helps students work with the interactive. This resource is part of the Math at the Core: Middle School Collection.

• ## Number Line Party: Rounding to Whole Numbers

Only whole numbers can get in to the number line party, what's a decimal to do? This interactive exercise focuses on using what you know about number lines and rounding from the tenths place to make decimals whole numbers and then asks you to explain your reasoning to show comprehension.

• ## Real-Life Math | Baseball

Watch and listen as the assistant general manager of a major league baseball team explains how he uses math in this video from KAET, Arizona PBS.

• ## Rotation and Dilation

In this video from KCPT, watch an animated demonstration of rotating and dilating a triangle on the coordinate plane. In the accompanying classroom activity, students watch the video; draw rotations and dilations of a triangle; and identify center of rotation, angle of rotation, and scale factors in classmates drawings. To get the most from the lesson, students should be comfortable graphing points on the coordinate plane and reproducing a drawing of a geometric shape at a different scale. Prior exposure to rotation and dilation is helpful.

• ## Scientific Notation

This animated Math Shorts video from UEN explains the term scientific notation and provides several examples in converting extreme numbers to and from scientific notation. It also demonstrates how to multiply numbers using scientific notation. In the accompanying classroom activity, students practice writing numbers in scientific notation and develop real-world problems for each other to solve. This resource is part of the Math at the Core: Middle School Collection.

• ## Setting Up A Proportion

In this interactive from APT, learn about ratios and proportional relationships by figuring out the time it takes to charge the battery of an MP3 player and the length of play time. Then, figure out the length of shooting time on a camera. In the accompanying classroom activity, students practice calculating proportions and use language to describe the ratio relationships.

• ## Stop the Machine!

In this interactive from WNET, shut down a series of creature-controlling machines by determining the solution to a function. When changing one quantity determines the value of another, they are connected by a rule you may not see. Find the rule and you can predict any outcome. In the accompanying classroom activity, students use a deck of playing cards to see if they can use what they learned in the interactive about rules, functions, and numbers in another game called "Mystery Envelope." This resource is part of the Math at the Core: Middle School Collection.

• ## The Lowdown | Defining and Calculating Percents

Learn how to calculate and compare discounts in this video from KQED. In the accompanying classroom activity, students develop different strategies for calculating and comparing discounts, including percent off a price, percent of a price, and dollars off a price. They compare their strategies with those demonstrated in the video. Then, they write and solve story problems involving comparing percent off and dollars off a price. To get the most out of the lesson, students should be familiar with percent as a rate per 100 and comfortable calculating percent of a dollar amount (e.g., 80% of \$80, 1% of \$130).

• ## Thinkport | Mapping Sculptures

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.

• ## Hosting a STEM Day

Learn how Google partnered with cultural institutions to create a “Geek Fair” celebrating STEM education in this video from MetroFocus. The focus of the fair was providing hands-on activities for children. Activities included operating a robot, building circuits, solving math puzzles, and studying fossils. By getting children interested in science and technology, the organizers hope to inspire more people to study these fields in the future.

See the "STEM Day Activities" handout in the Support Materials section for more engaging STEM ideas.

• ## Math in Fashion

Following a profile of fashion designer and Project Runway winner Chloe Dao, students are prompted to alter garment designs, using their sense of style combined with their math skills to hit target price points. Algebra concepts explored include: linear relationships; rates (percents), ratios, and proportions; using multiple representations; algebraic and numeric expressions, equations, and inequalities.

• ## Math in Restaurants

Students are introduced to Sue Torres, an accomplished chef and restaurant owner and learn how she uses math in her work. Sue presents teams with a mathematical restaurant challenge: find the best price point to charge for guacamole, a popular item in the restaurant by identifying what she should pay for avocados, the main ingredient. In this lesson, students focus on understanding the Big Ideas of Algebra: patterns, relationships, equivalence, and linearity; learn to use a variety of representations, including modeling with variables; build connections between numeric and algebraic expressions; and use what they have learned about number and operations, measurement, statistics, as applications of algebra.

Learn how Rocking the Boat engages and supports students as they design, build, and launch boats in this clip from American Graduate Day 2014. Rocking the Boat is a nonprofit organization that gives students in the Bronx in New York City hands-on engineering experience. Students use the boats they build to monitor water quality in the Bronx River. The organization provides additional support through social workers and college readiness programs.

Use the activity "Rocking the (Recycled) Boat:An Eco-friendly Rain Gutter Regatta" in the Support Materials to teach engineering skills to your students.

• ## Greenhouse Labs in Schools

Learn how New York Sun Works is bringing greenhouse labs to schools in this video from PBS Newshour Weekend. Because the green houses use hydroponics, a method of farming using water and nutrients instead of soil, the greenhouses are lighter and can be built on urban school roofs. New York Sunworks helps coordinate the funding, designing, and construction of the greenhouses. The greenhouses serve as labs, enabling students to learn about environmental science concepts as they grow plants. The curriculum teaches science standards as students learn about urban farming.
