This video module presents an introduction to cryptography - the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrypt messages. There are no prerequisites for this lesson, and it has intentionally been designed in a way that can be adapted to many audiences. It is fully appropriate in a high school level math or computer science class where the teacher can use it to motivate probability/statistics or programming exercises. nteractive lesson, students will learn to build the cryptography devices and will learn how to send and ''crack'' secret messages.

This is an integrated lesson which is introduced using the book "The Very Hungry Caterpillar" by Eric Carle. Butterfly metamorphosis is explored through art, math, and writing.

8th grade student will apply Newton’s Laws to design, test and evaluate materials to create the most protective helmet for an activity of their choice. Students will use force sensors and Vernier software to analyze the force reduction for their helmets. The culmination of this project is for students to write and present a sales pitch to promote their helmet to their peers at an annual "conference."

CK-12 Third Grade Math Resource FlexLet is intended to be used as a resource to help students get back up to speed. Teachers can assign sections to a class or parents can walk through sections with young learners. Each section is also paired with short videos to walk through examples as well as practice questions to check for mastery.

This Geometry Concept Collection is a rigorous presentation of high school geometry. It is fully correlated with the Common Core State Standards.

This lesson will focus on applying basic math skills to determine current inventory on hand at a business or in the home, and calculate the number of items needed. In addition, learners will determine the costs to replace items and apply the amount to an overall budget.

This site provides lectures and guided lecture notes for students for a second-semester calculus course.

This is a lesson on finding the difference between an implicit and explicit function and finding the derivative of functions implicitly. It also covers finding the equation of a tangent line from a function in implicit form . There are self check throughout the lesson. The text that I use in my calculus class is Larson Calculus 11th edition. This corresponds to chapter 2 section 5 in that text but Implicit Differentiation is a common topic in any Calculus I or AP Calculus course.

Students will use their knowledge of appropriate tools and units and determine when to measure liquid volume or weight.

In this lesson, students calculate their own carbon footprint using Peter Kalmus's methodology in his book Being the Change: Live Well and Spark a Climate Revolution.

Step 1 - Inquire: Students watch a short video on the climate crisis. Students engage in a brief discussion on the prompt "Do my individual actions matter?"

Step 2 - Investigate: Students calculate their own carbon footprints.

Step 3 - Inspire: Students engage in a discussion, reflecting on this activity and the importance of individual actions.

Checklist for students to use to ensure that all aspects of a constructed response math problem are answered and checked over before completion. 

This resource was created by Heidi Meyers, in collaboration with Dawn DeTurk, Hannah Blomstedt, and Julie Albrecht, as part of ESU2's Integrating the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education, practice, and coaching.

An interactive applet and associated web page defining a circle. The applet shows a circle where the user can drag the center and a point on the circle. The radius line supports the definition that all points on the circle are a fixed distance from the center. The web page has the definitions of all the circle-related objects, such as diameter, chord etc, with links for each. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that show the properties of a circumcircle of a polygon. The applet shows a regular polygon where the user can drag the vertices to reshape it and alter the number of sides. As the polygon is being varied, the circumcircle is shown, passing through all vertices. The text describes two ways to calculate the radius of the circumcircle, depending on what you are given to start. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that demonstrate the circumference of a circle. The applet shows a circle with a radius line. The radius endpoints are draggable and the circle is resized accordingly. The formula relating radius to circumference is updated continually as you drag. Introduces the idea of Pi. The formula can be hidden for class discussion and estimation. See also the entries for circumference and diameter. See also entries for radius and diameter. Applet can be enlarged to full screen size for use with a classroom projector.

This lesson introduces solar energy and tasks students with solving an algebraic equation to determine the amount of daily sunlight needed to make a solar panel effective.

Step 1 - Inquire: Students work through a practice problem and discuss what they already know about solar energy.

Step 2 - Investigate: Students briefly learn some background information about solar energy and then use algebra to calculate the amount of peak sun hours needed to make a solar panel effective. Students compare their calculated values to real-world data to determine if this amount of sunlight is possible in their area.

Step 3 - Inspire: Students make predictions and discuss if they think their home could be powered by solar panels using the calculations from class as evidence.

This unit provides Common-Core aligned lessons based for Math 3, English 10, and Biology (NGSS Standards). The subjects are linked by a text on climate change, and they hit the standards of argumentation for English, comparing functions in Math 3, and human effects on environment in Biology.

This College Algebra textbook provides a comprehensive introduction to the fundamental concepts of algebra, with a unique focus on the concept of inverses. The textbook begins with an exploration of the foundational principles of functions, including domain, range, and the vertical line test. It progresses through critical topics such as operations on functions, composition of functions, and the algebra of functions, ensuring students grasp the fundamental building blocks necessary for more complex algebraic thinking.Several times the teaching diverges from how the subject is commonly taught. Examples include absolute value, determining the inverse of a function, and completing the square. The text is as devoid of "gimmicks" or "tricks" as possible, leaning on the fundamentals of good algebra. Also, there is a high reliance on fractions, rather than decimal numbers, to help equip the student with the better way to read a problem and its solution.This book is written for and dedicated to my grandchildren, and the fact that you're taking at least a glimpse of it is just a huge bonus! Thank you.

Students will practice skills in problem solving and verbally communicating the steps to solving using Flipgrid.
