Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.

Students study relationships between angles, side lengths, perimeters, areas and volumes of similar objects. For this lesson students also create and critique inductive and deductive arguments concerning congruency, similarity and the...

Students differentiate between similar and congruent polygons. In this geometry lesson, students define the theorems and reasons for polygons similarity and congruence. They are given pictures and patterns to differentiate and identify.

Students simulate crater formation using mud. In this earth science lesson plan, students identify the features of a crater. They explain how the force of impact affect the crater's appearance.

Seventh graders participate in a polygon hunt.  In this polygon lesson, 7th graders examine how polygons are alike and different.  Students create a Venn diagram and label the sorting circles.  Students work in cooperative...

Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, students identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and right...

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.

In this polygon worksheet, 5th graders name 6 polygons, tell if each one is a regular polygon or not and tell if it is a special quadrilateral.

Fourth graders create mandalas. In this mandala lesson, 4th graders look at these polygons in nature and man-made forms. They create their own by using tangrams.

Pupils identify geometrical shapes displayed in photographs of everyday objects in a metropolitan setting.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Young scholars view and discuss the public television program, Wide Angle: Young, Muslim, and French. They research and write a position in favor of or against the headscarf ban in France, and examine the influence of media in shaping...

Second graders Make, name and describe, using their own language and the language of geometry, everyday shapes and objects. They create and talk about geometric patterns which repeat (show translation), or which have rotational or...

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students use Geometers SketchPad to find the area and perimeter of several shapes. For this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Students identify the differences between non-renewable and renewable energy sources. They construct a PVC wind turbine and design a set of blades to extract as much energy as possible from low and high wind conditions.

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Second graders describe a polygon in the form of a riddle.

Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, students use a computer applet to explore four-sided figures and classify them according to their attributes. The...

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

What features mark a building as belonging to a particular culture, time, and place? Class members investigate the architectural movements represented in structures built in Forsyth County, North Carolina from 1880-1980 by examining...

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...
