Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Eighth graders become engaged in a lesson plan in geometry to improve mathematical skills. They construct triangles, segments, and points using Geometer's Sketchpad to demonstrate how dilations of triangles and rectangles change...

Seventh graders investigate geometric shapes using tessellations. In this geometry instructional activity, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Young scholars explore the concept of paragraph proofs. In this paragraph proofs lesson, students make flow charts of the process of getting ready for school. Young scholars convert the flow chart to a paragraph proof. Students use...

Young scholars construct two-column proofs. In this geometry lesson, students use deductive reasoning and geometric properties to justify given geometric statements. Young scholars compare and contrast proofs.

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

In this math activity, middle schoolers practice drawing the lines of symmetry for each of the polygons. They also draw mirror images for the figures.

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

Students explore geometry by creating jewelry in class. In this polygons lesson, students identify different shapes and characteristics while creating polygon figures from construction paper. Students utilize a multitude of shapes...

In this area instructional activity, students figure out the area of complex shapes containing 90' angles. Students find the area for 2 shapes.

Students study geometric images and polyhedrons. In this geometry lesson, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed...

Fourth graders use computer drawing tools to create a house of geometric shapes.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Fifth graders review the concept of a line of symmetry by using pieces of paper that have pictures such as, letters of the alphabet, polygons, and designs made from polygons in order to determine if they have symmetry. The fine,...

An outstanding lesson on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed...

A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Students see how to identify regular polygons, how to slide, turn and flip polygons, and why certain polygons tessellate better than others. Groups create a one foot square design to be used to tile the classroom. Great lesson plan!

Transform your lesson plan on transformations. Learners use given congruent triangles and tracing paper to determine the single transformation that carries one to the other. The concept is extended to combinations of transformations...

Turn your class upside down as they explore the reciprocal functions. Scholars use the unit circle to develop the definition of the secant and cosecant functions. They analyze the domain, range, and end behavior of each function.

Continue the study of transformations with an examination of horizontal stretches, shrinks, and reflections. Individuals use the same process used in parts one and two of this series to examine horizontal changes. The resource also...
