Exact narrative and examples make this lesson on polygons easy to implement. Through it, your class will learn how to use a protractor and ruler to construct triangles and quadrilaterals according to your directions. Your class will be...

Guide your geometers through the process of constructing polygons. They learn how to draw triangles, squares, parallelograms, rectangles, rhombuses, and trapezoids with specified angles using a protractor and a ruler. The lesson plan...

Students view a video to discover how patterns in nature relate to math. They explore the concept of exponential growth by observing and creating fractals. They solve and design word problems.

Students study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

Teach your pupils to calculate the area of different polygons. Learners create formulas to solve their problems. They use the TI navigator to graph their shapes and observe the change in area.

Fifth graders play Battleshapes which is a variation of Battleship with geometry. In this geometry lesson, 5th graders get a graph paper with four quadrants. They call out coordinate points and attempt to sink their opponents shapes. 

In this tessellations activity, students answer questions about the characteristics of tessellations.  They identify polygons that will and will not tessellate.  Students determine the sum of angles in a polygon...

Students explore the mathematical properties of traditional American Indian lodges. They examine the effect of increasing sides of a polygon, calculate the surface area of prisms and cylinders, and construct a classroom size pyramid...

High schoolers engage in a lesson that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the...

Here is an online lesson plan on data representation. In it, learners access websites embedded in the plan which lead them through a variety of activities around data representation and statistics. The activities are quite good, and...

Students use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .

In this square unit instructional activity, students read the word problem about the pens Farmer Mathman wants to build for his animals. Kids then use the table to guide them. Students draw their answers on grid paper and then answer the...

In this tessellating a hexagon worksheet, 10th graders complete 2 activities in creating a tessellation of a hexagon. They start off with the tessellation by the smallest pattern block and obtain other tessellations by replacing each two...

Young scholars explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students...

Using a TI Navigator to drag quadrilaterals around to create different shapes, students learn how to draw midpoints in their quadrilaterals. In this geometry lesson, students solve problems using the properties of quadrilaterals. 

In this tessellation worksheet, students draw tessellations using specified figures. This one page worksheet contains five multi-step problems.

Students identify properties of triangles. In this geometry lesson, students differentiate between similar and congruent triangles. They use the umber of sides to help define the angle of the polygon.

High Schoolers investigate the question of whether or not the area of square can be trisected. In this lesson, they use geometry software to answer the questions and determine what conditions are necessary to the three regions to by equal.

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Middle schoolers use historical aerial photographs and current aerial photographs to compare the change over time to the land. In this land changing lesson plan, students analyze, compare, contrast, and list the land change in their own...

Students identify and use the computer keyboard to complete simple tasks. Students eliminate the use of the computer mouse to do simple jobs. They use keys that are used alone, keys that specify object labels, Keys that result in objects...

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