Students use pair programming to trace, annotate and debug a prewritten Twine story. Students then add modifications to the existing code and extend the story.

In this lesson, students will explore the “Testing Random Numbers” program to learn how to generate random numbers and use if-statements to make comparisons. Then, they will create a “Roll the Dice Game” to learn how to work conditionals and random numbers. At the end, students will create a simple program applying their knowledge of randomization and conditional control structures. This lesson is part of CodeVA's ECS+Python lesson set, providing alternative units for the Exploring Computer Science curriculum covering basic Python coding concepts.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

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!

Variables are used as placeholders for values such as numbers or words. Variables allow for a lot of freedom in programming. Instead of having to type out a phrase many times or remember an obscure number, computer scientists can use variables to reference them. This lesson helps to explain what variables are and how we can use them in many different ways. The idea of variables isn't an easy concept to grasp, so we recommend allowing plenty of time for discussion at the end of the lesson.

In this lesson, students will explore the creation of repetitive designs using variables in the Artist environment. Students will learn how variables can be used to make code easier to write and easier to read, even when the values don't change at runtime.

This lesson will help illustrate how variables can make programs more powerful by allowing values to change while the code is running.

In this lesson, students will explore the creation of repetitive designs using variables in the Artist environment. Students will learn how variables can be used to make code easier to write and easier to read. After guided puzzles, students will end in a freeplay level to show what they have learned and create their own designs.

Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with objects on a balance. Discover the rules for keeping it balanced. Collect stars by playing the game!

In this activity, students use their knowledge of variable substitution and one-step equations to find the missing values in similar puzzles.

In this lesson, students engage in a historical jigsaw activity focused on westward expansion. The lesson ends with a coding project where students create “postcards” by coding with Twine, expressing the perspectives of different groups experiencing the effects of westward expansion.--

Students will analyze data from the "State of the Bay" reports from the Chesapeake Bay Foundation while reviewing and completing the scientific method. The final assessment is a mission for students to create a persuasive speech or advertisement that will call for action to make changes that will positively impact the watershed with reasons why change is important. 

In this lesson sequence, students will work in teams to learn the MakeCode and Micro:Bit Development platform. They’ll develop basic programming skills, implementing input, output, variables, and conditional control structures. At the end of the sequence, students will compete in a “puzzle box” challenge, attempting to create a puzzle using their Micro:Bit, code, and craft supplies and earning points based on how challenging their puzzle is to solve.

NASA eClips Real World:  Food Security -- Monitoring Crops from SpaceVideo Description:  Discover how NASA's Earth-observing satellites gather data to monitor food growth. Dr. Inbal Becker-Reshef describes how mathematics is used to interpret satellite data and describe vegetation and crop yield. Dr. Hannah Kerner shares how algorithms and models use NASA data to describe and predict food supply and food shortages. This work through NASA Harvest provides tools for farmers and governments to describe and predict food security worldwide. Video Length:  5:25.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.
