Title: Using Number Lines to Model Real-World Problems
Description:

In this activity, students will compute real-world problems with rational numbers while using a digital number line. Students are provided a sample problem to work through to become familiar with the digital number line. Since problems can be solved using multiple methods, students are asked to provide a number sentence to represent their number line model as well as the solution to the problem. Through the online digital tool, students can also share a link to their work with their teacher or classmates. This provides a great opportunity for students to investigate how to solve problems using multiple methods.

Title: How Do Algorithms Predict Criminal Behavior?
URL: https://aptv.pbslearningmedia.org/resource/criminal-justice-kqed/how-do-algorithms-predict-criminal-behavior-above-the-noise/support-materials/
Description:

It’s no big secret that the United States has a prison problem. We lock up people at higher rates than any other nation, and there are huge racial disparities in who we lock up. According to a study from The Sentencing Project, in state prisons, African Americans are incarcerated 5 times more than whites. There are lots of reasons why we may see these racial disparities, including law enforcement practices, crime rates, and punitive sentencing policies. Keeping so many people in prison is really expensive-- it costs about \$80 billion dollars a year-- and it contributes to racial inequalities in America. As a result, there’s a big push among both Democrats and Republicans to reform our prison system. And one popular strategy many people advocate for as part of this reform effort is risk assessment tools. The tools use data to predict whether a person will commit a future crime. This video explores how these tools work and some of the controversy surrounding their use. This video comes with a student viewing guide.

Title: Design Thinking
URL: https://www.remc.org/21Things4Students/21/15-design-thinking/
Description:

Design Thinking is a process for designing something to solve a problem. It shares a lot of similarities to the Engineering Design Process you might learn in a STEM class and the Scientific Method you learn in science. However, it tends to work really well with creating solutions to problems that impact humans, also known as Human-Centered Design

In this activity, you’ll work with a team to identify a problem, come up with ideas to solve it, make a prototype of your best idea, test it out and ultimately share it. Your goal is to make a positive impact on the problem you choose.

Title: Computational Thinking
URL: https://www.remc.org/21Things4Students/21/21-computational-thinking/
Description:

Have you ever had a complex problem that you needed to solve? This could be a math problem, science experiment, an essay you need to write, and coding and game design. It could even be as simple as planning the best route to school or baking your favorite cookies!

Computational thinking can be used to take a complex problem, understand what the problem is and develop possible solutions to solve or explain it.

Students will complete Quests to learn about the four stages of computational thinking:

• Decomposition: Decomposition is to break down a complex problem or system into smaller, more manageable parts.
• Pattern Recognition: Pattern recognition is looking for patterns and sequences.
• Abstraction: Abstraction is focusing on important information only, ignoring irrelevant detail.
• Algorithms: Using algorithms you develop a step-by-step solution to the problem, or the rules to follow to solve the problem.

Title: Minimal Spanning Trees
URL: https://classic.csunplugged.org/minimal-spanning-trees/
Description:

Networks are everywhere in modern society: roads, wires, water and gas pipes all connect one place to another. Computers are built of networks at many levels, from the microscopic connections between transistors in a chip to the cables and satellites that link the internet around the world. People who build networks often need to work out the most efficient way to make connections, which can be a difficult problem.

This puzzle shows students the decisions involved in linking a network between houses in a muddy city. It can lead to a discussion of minimal spanning tree algorithms for optimizing networks.

Title: Computer Science Discoveries Unit 5 Chapter 2 Lesson 9: Problem Solving and Data (18-19)
URL: https://studio.code.org/s/csd5-2018/stage/9/puzzle/1?section_id=1888730
Description:

In this lesson, students use the problem-solving process from earlier in the course to solve a data problem. After reviewing the process, the class is presented with a decision: whether a city should build a library, pet shelter, or fire department. Students work in teams to collect information on the Internet to help them decide what should be built, then use this information to build an argument that will convince the city council of their choice. They map what they have done within the problem-solving process that they have been using throughout the course, comparing the general problem-solving process to its specific application to data problems.

Description:

To conclude this unit, students design a recommendation engine based on data that they collect and analyze from their classmates. After looking at an example of a recommendation app, students follow a project guide to complete this multi-day activity. In the first several steps, students choose what choice they want to help the user to make, what data they need to give the recommendation, create a survey, and collect information about their classmates' choices. They then interpret the data and use what they have learned to create the recommendation algorithm. Last, they use their algorithms to make recommendations to a few classmates. Students perform a peer review and make any necessary updates to their projects before preparing a presentation to the class.

URL: https://studio.code.org/s/csd6-2018/stage/16/puzzle/1?section_id=1888730
Description:

Students, working with a partner or team will brainstorm physical devices they wish to prototype. Students have the option to design a new creation or recreate a device they have found in the "real world". Students will complete a planning guide to determine the resources (physical and digital) they will need to create their prototype. Students will design a user interface (typically an app or circuit board) that may control some output device (like a circuit board). It will be necessary for students to develop pseudocode or algorithms to aid in the coding process. Students will need to complete the problem-solving process during this lesson plan which will include testing a revising the prototype.
