Students define the five rules of loci. In this geometry lesson, students identify the locus of points that creates a circle. They calculate the distance from a fixed line and point.

Students watch and discuss an M. C. Escher video, use what they have learned to explain and apply their knowledge of tessellations in order to create a slide translation, present their findings in a 12" x 18" poster, and explore...

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students examine tessellations and their geometric properties. The lesson plan and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Fourth graders examine the simple machine known as a plane. They build their own pyramid and identify the role of screws. They participate in a hands-on activity in which they determine the angle in which to make it easier to pull.

Young scholars examine the mathematical relationship in scoring a basket. They observe the arc of the ball as it travels to the basket from different points on the floor.

Parallel lines seem so right for each other. It's too bad they'll never, ever meet. Learners use tracing paper to discover relationships among angles formed by two parallel lines cut by a transversal. They apply this information to find...

Students investigate geometry with the use of a creative project. They review relevant vocabulary that includes turn, flip, side, and angles. Students also practice conducting transformations used as inspiration for the project. Then...

For any study of upper-level geometry, this presentation could be of good use. It defines three important concepts: transformation, reflection, and rotation. Although brief, this presentation could easily be used in tandem with problems...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

Third graders engage in an enrichment lesson 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. They then create a...

In this transformations instructional activity, 10th graders identify and complete 10 different problems that include various types of transformations. First, they label each figure with the correct term listed on the top. Students also...

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

Students visit different departments at a local hospital to see how machines help peoples such as the CAT scan machine. They build a model of such a machine that shows how patients are moved in and out of the machine.

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.

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

Young scholars 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. Young scholars identify different geometric...

Students create a glossary of geometric terms while exploring tangram manipulatives.

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

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...

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

Students 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. ...
