An interactive applet and associated web page that demonstrate the concept of similar triangles. Applets show that triangles are similar if the are the same shape and possibly rotated, or reflected. In each case the user can drag one triangle and see how another triangle changes to remain similar to it. The web page describes all this and has links to other related pages. 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.

This is an activity for students to work on in pairs practicing simple interest. It involves real online research and presents an open-ended question. This would be most effective after students have had instruction and some practice.

This resource can serve as a teaching module, student self-study material, or evaluation of understanding. It explains and evaluates the concepts and calculations regarding simple and compound interest. It was developed by Martha Donnelly of Lone Star College.

Build coin expressions, then exchange them for variable expressions. Simplify and evaluate expressions until you are ready to test your understanding of equivalent expressions in the game!

In this seminar you will learn how to simplify square roots whose radicands contain factors that are perfect squares. You will learn how to perform these operations on both integers and variables. You will be able to do this by learning how to identify factors that are perfect squares.  These will be necessary skills as you continue to perform operations that contain radical expressions.   StandardsCC.2.2.8.B.1Apply concepts of radicals and integer exponents to generate equivalent expressions.

Math lessons with an emphasis on relevance and mathematical reasoning.

This video gives students an audio and visual way to learn to skip count by 3's.

An interactive applet and associated web page that demonstrate the slope (m) of a line. The applet has two points that define a line. As the user drags either point it continuously recalculates the slope. The rise and run are drawn to show the two elements used in the calculation. The grid, axis pointers and coordinates can be turned on and off. The slope calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of slope, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

This lesson features a comparison of different travel options from New York City to six other cities. Students compare walking, biking, driving, taking the bus, riding the train, and flying. Students conduct research and calculate the CO2e for each travel option.

Step 1 - Inquire: Students watch a short video on the climate crisis. In groups, students explore and discuss emissions from the transportation sector.

Step 2 - Investigate: Students are assigned one route between New York City and another city in the Northeast. Students calculate miles, cost, time, and CO2e for each travel option for their route.

Step 3 - Inspire: Students participate in a group discussion about the results and explore different ways to decarbonize our transportation system.

Students will measure the dimensions of containers in the garden to determine the volume of soil and work out computations based off the volume.

In this project students will research and then build a basic solar cooker shell made out of cardboard. Then they will run a variety of materials through experiments. Data from the experiments will be used to determine which materials should be added to the solar cooker shell to improve its ability to heat up food.

This project was created as a collaboration between a science and an engineering/woodshop class. The engineering class researched and build the basic solar cooker cardboard shells. The science class tested additional materials to add to the shells to improve the solar cookers. Then the engineering class, following the directions from reports created by the science class, added the materials to the solar cooker shells to create the final products.

This seminar will explore how to solve systems of equations using elimination. You will discover the most efficient methods of preparing a system to be solved using elimination and how to identify the best variable to eliminate.StandardsCC.2.2.HS.D.10Represent, solve, and interpret equations/inequalities and systems of equations/inequalities algebraically and graphically.
