Challenge young mathematicians' ability to compose and decompose shapes with this fun geometry puzzle. The goal is simple, locate all of the rectangles shown in a picture of three overlapping rectangles. Perform this activity as a whole...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

For this secondary mathematics worksheet, students determine the number of times in which the two hands of a clock overlap during a given twelve hour period.  The one page worksheet contains one problem with the solution.

Triskaidecaphobia is an extreme superstition to the number 13—and ironically the answer to the word problem is 13! Presented with a series of descriptive data, individuals analyze the data to determine the population size. They...

In this geometry worksheet, 10th graders determine the area of a shaded region formed from two overlapping squares where one corner of one square is at the center of the other square.  The one page worksheet contains one...

Second graders use oil pastels or chalk in bright colors to create depth in art by overlapping the forms in their art. They practice by drawing a lollipop, and then the teacher keeps adding lollipops to be drawn.

Third graders find the area of rectilinear shapes by partitioning them into two non-overlapping rectangles and adding the areas of the non-overlapping parts together. It allows learners to recognize area as an additive.

Explore non-fiction comprehension strategies with your class. They will visualize daily activities and label a 4 circle Venn diagram with related phrases. They must identify the overlapping sections as "main ideas," then complete a...

Demonstrate for your earth scientists how plant pollen of the past has become part of sedimentary deposits, providing clues about ancient climates. Then give them simulated sediment layer samples to analyze for different types of paper...

By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference. 

Don't be fooled by the size of the resource: these few pages provide the blueprint for a substantial, thoughtful unit on children's rights and the different philosophies and approaches that the United States and other countries have...

A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

Introduce this abstract art to your class; they must chose ordinary classroom objects and shapes to paint with watercolors. The overlapping effect will create a fun, abstract piece of art!

There are many different options for graphing data, which can be overwhelming even for experienced mathematcians. This time, the focus is on histograms and Venn diagrams that highlight the frequency of a range of data and overlap of...

Students create non-objective art based on the design elements of line, color, balance and movement using tape. This simple lesson plan encourages students to create patterns by overlapping and defining lines on a canvas panel. One of...

See how art can communicate the idea of working together with your class. They will view art and describe space, color, shape, and lines in art. Then they will overlap in their art to show a sense of space. In the end, they will be able...

What’s in a name? Letters, of course! Partners place the letters of their names on a Venn diagram. Letters they have in common are named and placed in the overlapping area of the circles, while letters unique to just one of the names are...

Students perform an activity in which they discover what happens when food chains overlap in an ecosystem and discover the three components of a food web.

Let's make colors! Your class will participate in a creative art project that introduces them to the concept of color blending and allows them to discover color combinations through exploration, trail, and error. First, the teacher will...

To reinforce shape recognition and identification, little learners create a shape collage. They name each shape as they go, gluing or pasting them onto bright paper. They discuss collage techniques and are encouraged to use their shapes...

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

A thorough examination of Andrew Jackson's presidency and politics, these slides contain important facts and pictures of the growing United States. Events such as the Trail of Tears and the Tariff Battles of the early 19th century are on...

Some formatting issues will need repair (a few overlapping text boxes and pictures), but overall this is a comprehensive presentation on how light reflects off of spherical mirrors. Both convex and concave mirrors are explained,...
