Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Young scholars calculate the surface area of different prisms. In this geometry lesson, students identify the shapes of solids based on the properties of that solid. They calculate the surface area using nets and properties of prisms.

Fifth graders draw 2-D and 3-D shapes. They sketch and label geometric figures with correct terminology, then explore parallel and perpendicular lines. Pupils sort and classify shapes drawn.

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Elementary schoolers examine the attributes of triangles. In this triangle instructional activity, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils...

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Middle school geometers determine the area of a shape on a geoboard or dot paper and draw figures that meet given area conditions. Working as a class, they develop and discuss various ways to draw geometric shapes with specified...

Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Exact narrative and examples make this lesson plan 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...

Students practice theories dealing with equals sign used as a balance, inequality symbols and practice utilizing a box or some other geometric shape to represent an unknown number. They assess numeracy problems embedded in language-rick...

Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Eighth graders study and analyze the elements of color by creating an personalized color wheel. Emphasis is placed on constructive criticism of student work by others for assessment. Students create short poems for their color wheel...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

After completing a task involving examining the ratio of areas of triangles and circles in a given figure, scholars examine sample responses to identify other strategies they could use to solve the problem.

Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Fifth graders classify triangles. In this triangle instructional activity, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...
