Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

Young scholars create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.

In this math activity, students determine the name for each triangle according to its classification. Then they create a truss construction model.

Fourth graders explore obtuse triangles. In this geometry lesson, 4th graders make obtuse triangles with paper and scissors. They determine how to find the center of their triangle.

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

In this geometry review game worksheet, students use the provided game cards and calling cards to play a Bingo-like game. Students learn geometric terms while playing a group game.

Young scholars use the inequality theorem to solve triangles and their properties. In this geometry lesson plan, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed...

Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Students classify, flip, slide, and turn a quantity of quadrilaterals.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Students construct two dimensional models to illustrate squared numbers. For this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various...

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...

For this triangles practice worksheet, students sharpen their problem solving skills as they solve 6 story problems.

In this secondary mathematics learning exercise, high schoolers expand a six-panel play yard by two-panels  Students determine the width of each panel and the area of the expansion. The one page learning exercise contains one...

Young scholars 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.

Students explore the history of Pythagoras and his contributions to mathematics. In this middle school geometry lesson, students use one inch tiles to investigate the Pythagorean Theorem and to find the length of the sides of a right...

Fifth graders work with polygons.

Students investigate the properties and idea of the Pythagorean Theorem. In this algebra lesson, students identify the different parts of a right triangle and relate it to the Pythagorean Theorem. They do a robotic experiment to...

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

In this mental math worksheet, students use mental math to find the surface area and determine nets of the given shape. They use an information sheet as an aide to find the answer to 30 questions.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Eighth graders engage in a lesson that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as polygons.
