An interactive applet and associated web page that provide step-by-step instructions on how to divide a line segment into any number of equal parts, using only a compass and straightedge. The applet starts with a given line segment and ends with that segment divided into n parts. In the applet n=5, but the construction works for any n. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. The text on the page has printable step-by-step instructions. 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 task is for students to get to thinking about college and the costs that come with going to college.

This resource was created by Sandy Schneider, 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.

Students will practice counting up to 20 in a very fun and exciting way. The lesson includes a hands-on component where students will be asked to collect leaves and use them as manipulatives. This lesson is great for kindergarten through first grade.

The attached file is our syllabus for the Introductory Statistics course that we are teaching as an OER course. The summary of the syllabus is as follows.This course uses MyOpenMath for testing students' knkowledge via homework and quiz assessments. MyOpenMath is an open platform for students to use without any additional access fees like the one for our other statistics courses which charge an extra fee to use a different online platform.This course uses MS Excel as the statistical tool. We have created templates for students to use to evaluate statistics for a given data. Students have access to all Microsoft products via their college account without any extra charge. Using Excel also eliminates the need for buying a calculator.A big part of the course is the project, which is based on real world data. Students are provided with data in a spreadsheet by the instructor. Data is mined from public domains. Students are to submit their input using MS Word and MS Excel.We are also using MS Teams to record additional video resources on using Excel for statistics.

In this lesson, students will use a square foot gardening planting chart (provided) to calculate the number of crops they can plant within a specific area.

An interactive applet and associated web page that demonstrate the properties of a cube. A 3-D cube is shown in the applet which can be interactively manipulated using the mouse. Research has shown that some younger students have difficulty visualizing the parts of a 3D object that are hidden. To help with this, the student can rotate the cube in any axis simply by dragging it with the mouse. It can also be 'exploded' - where a slider gradually separates the faces to reveal the ones behind. The cube can also be made translucent so you see through it to the other side. Applet can be enlarged to full screen size for use with a classroom projector, and printed to make handouts. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

The purpose of this curriculum guide is to provide OER lesson material and support activities for Pythagorean Theorem instruction. It is geared towards GED® requirements. Both printable and online options are provided.

With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. In his talk, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think. (Filmed at TEDxNYED.)

In this lesson, students analyze data, create line graphs, conduct research, and plan their data art project.

Step 1 - Inquire: Students analyze their own data from the previous lesson.

Step 2 - Investigate: Students create a line graph and conduct research on their topic.

Step 3 - Inspire: Students plan their data art project.

Students will convert vegetable bed measurements from feet to metric units using decimals.

This unit is an EQuIP Exemplar for adult education (http://achieve.org/equip). Students will connect their prior, real-world knowledge to the concept of order in mathematics. They will go through a discovery process with content that will build a deep, conceptual understanding of the properties of operations to explain why we perform operations in a certain order when we see just the naked numbers.

Adult Educators do not have a lot of time to dive into dozens of resources spread all over the internet to try to find the essential items they need to create a high-quality lesson for their students. This guide is designed to walk you through each step of creating a math lesson-plan with recommended OER that you can evaluate.

With each step of the guide, I create a sample lesson on learning the Pythagorean Theorem. By the end, you have an entire lesson plan example for this concept.

Students learn about the mathematical characteristics and reflective property of ellipses by building their own elliptical-shaped pool tables. After a slide presentation introduction to ellipses, student “engineering teams” follow the steps of the engineering design process to develop prototypes, which they research, plan, sketch, build, test, refine, and then demonstrate, compare and share with the class. Using these tables as models to explore the geometric shape of ellipses, they experience how particles rebound off the curved ellipse sides and what happens if particles travel through the foci. They learn that if a particle travels through one focal point, then it will travel through the second focal point regardless of what direction the particle travels.

This video explains and shows definitions and example of the words: volume, area, surface area, and base. It also talks about word problems associated with volume and area. Students need to figure out if the provided story problems are finding the correct thing, volume or area, based on the object. Explanations of the correct answer are provided.

An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line using trigonometry, given the coordinates of the point and the slope/intercept of the line. The applet has a line with sliders that adjust its slope and intercept, and a draggable point. As the line is altered or the point dragged, the distance is recalculated. The grid and coordinates can be turned on and off. The distance 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 the concepts, 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.

Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.
