Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

Fourth graders investigate congruent shapes. In this congruency activity, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Third graders are introduced to different types of transformations. As a class, they describe how a stuffed animal slides across the floor and use themselves to demonstrate as well. Individually, they flip and turn in different...

Students create entries for the Architects of America contest, including a model of a futuristic structure, blueprints, a list of all plane and solid shapes in the structure, a persuasive argument paper that describes why the structure...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

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!

Create geometric cups by interpreting directions, informational text, and mathematical concepts. Critical thinkers apply geometric theory (congruent shapes, patterns, symmetry) to actual directions to create a cup that holds Kool Aid....

Young scholars listen to The Important Thing About Quilt Design and rewrite an original version using geometric terms.

Second graders identify congruent figures and match shapes using transformation. They work in groups, utilizing a worksheet imbedded in this plan to gain practice identifying congruent shapes.

Students use an online dictionaries to define key geometric terms. They explore several websites to help them differentiate the terms reflections, translations and rotations as they apply to geometry and then complete an assessment...

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Second graders experiment with slides, flips and turns to understand motion geometry.  In this motion geometry lesson, 2nd graders navigate interactive motion geometry sites. Students  illustrate the results of motion using...

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

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This activity gives students a meaningful way to practice these...

Students discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.

Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the activity, they must...

Students listen to the book, Sam Johnson and the Blue Ribbon Quilt and discuss the art of quilting. They examine various symmetrical sewing designs, and identify reflection pieces, slides, and flips.

Learners brainstorm what they know about geometric terms and patterns. They identify symmetry, shapes and congruency. They create a book of symmetry.

Students explore botany by completing an art design activity in class. In this gardening history lesson, students identify the plants and crops utilized in the Colonial era for both food and medicine. Students utilize geometry to create...

Learners use the Internet to learn about transformations and tessellations.  In this geometry lesson, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry. ...

This activity introduces young scholars to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and

Young scholars 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. Young scholars complete worksheets based on...

Third graders engage in an enrichment instructional activity exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements....
