In this Algebra I/Algebra II worksheet, students determine the solution to a system of inequalities by graphing.  The two page worksheet contains explanation, instruction, and four worked problems. 

Students, using 15 years of sunspot data, plot data on a classroom graph. They discuss why the pattern from their individual sheets did not and could not match the class graph.

Try this problem - find the area of the overlapping region of two overlapping circles. You need to find the region of each segment, then add them up. This site gives the problem and a detailed written solution. Good problem for sharp...

A map interactive provides an opportunity for observations through overlapping maps. Students are able to better recognize spatial awareness through this program.

Do you know how to make a bright spot brighter? In this activity, your eyes will send conflicting information to the brain. See how you perceive what is on the paper.

In this applet you can adjust the parameters on two Gaussian curves to determine if there is a possibility of a difference between the two means.

In this lesson students will practice finding the area of rectangular shapes and irregular shapes with right angles and understand why the area formula works for rectangular shapes. CCSS.Math.Content.3.MD.C.5.b A plane figure which can...

Learn why recent discoveries are causing scientists to rewrite the timeline of modern humans and Neanderthals.

This picture shows three overlapping rectangles, one red, one blue and one green.

This exercise helps students understand how volume in figured, even when two or more parts of a prism are not overlapping. There is a teacher view, with a description of the activity and commentary, and a student view, with just the...

Step by step, this video lesson [4:34] will show you how to add up the number of squares that cover an object in order to find the area of a figure. It is 4 of 7 in the series titled "Finding Area with Squares."...

This article describes a new approach to teaching children more than just memorizing a formula to find area and hope they don't confuse it with perimeter. This approach involves a project with real life situations....

With this resource, students will explore how the illusion of depth is created by artists on a flat surface. By examining both a still life and a landscape, students will learn about foreground, middleground, background, and overlapping...

This lesson focuses on tessellations, a tessellation is a geometric pattern that covers a surface without gaps or overlaps. They can be seen everywhere in nature such as a honeycomb or a tortoise shell.

Step by step, this video lesson [2:41] will show you how to add up the number of squares that cover an object in order to find the area of a figure. It is 3 of 7 in the series titled "Finding Area with Squares."...

A lesson plan that introduces overlapping to 2nd graders as they learn how to construct a mural. Focus is given to artist Faith Ringgold and her children's book, Tar Beach.

Students use ratio and rate to answer this performance task: The data transfer rate of an Internet connection is the rate in bytes per second that a file can be transmitted across the connection. Data transfer is typically measured in...

Article describing efforts in the 19th and 20th centuries to determine the Earth's age, particularly using naturally occurring radioactivity. It notes that scientific disciplines frequently overlap in the work they do. Questions are...

An example is provided for the explanation of grouped frequency distributions. Graphs show how to construct histograms and overlapping bell curves, and Excel documents are discussed as being useful here.

Manipulate the primary color circles of light to see how overlapping the circles affect the colors. An explanation is included.

This is a very interesting site about polygons. The site begins by distinguishing between shapes whose sides intersect and polygons whose sides do not overlap. After this short introduction, you will find information regarding area and...
