Young scholars explore geometry by participating in a pattern identification activity. For this tetrominoes lesson, students define the characteristics of congruent and symmetrical shapes. Young scholars practice translating shapes...

Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.

Learners create a scrapbook. In this geometry instructional activity, students use digital cameras to take pictures of geometrical concepts. Learners use the pictures to create a "Geotown" scrapbook.

In this congruency worksheet, 5th graders complete 4 questions about congruent figures and transformations. Page has links to additional activities.

Students solve triangles using the properties if congruency. In this geometry lesson plan, students apply congruent and similar figures to solve real world and math problems. They show they are able to follow instructions.

Students relate topology to polygons. In this geometry lesson, students make the connection between different shapes and topologically equivalent relationships. They use Mobius strips to create and move shapes around.

Pupils create packages with a maximum capacity. In this geometry lesson plan ,students estimate using whole numbers, decimals and fractions. They calculate length, weight and mass of packaging.

Students solve problems using equations and properties of integers. In this algebra lesson, students solve problems using ratio and proportion and graph their answers on a coordinate plane. They solve word problems using geometry.

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Students explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Learners 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 explore encryption. They discuss the importance of cryptography in our daily lives. Students use games and cryptography to discover transformational geometry and modulo systems. They design their own encryption puzzles and...

Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Students observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

What was the property again? Tired of hearing this from your pupils? Use this table to organize properties studied and as a reference tool for individuals. Learners apply each property in the third column of the table to ensure their...

How can you prove it? Guide classes through an exploration of two possible triangle congruence criteria: AAS and HL. Learners connect this criteria to those previous learned and also explore criteria that does not work. The instructional...

There's more than one way to solve quadratic equations. Scholars learn how to solve quadratic equations using alternate methods. They use completing the square by making the linear coefficient even and the leading coefficient a perfect...

Pupils participate in a game with different types of polygons. They use triangles to create as many polygons as possible. They also review their colors by having different polygons be a different color.

Learners differentiate between ellipse and hyperbola. In this algebra lesson plan, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Learners explore geometric concepts using technology. They manipulate the TI to find important math topics. This activity requires a TI-84 or higher.

Show your learners how to create tessellations using different polygons. This is achieved by having students make observations of polygons to find the ones that will tessellate.

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...

Young geometers use the interactive website Cyberchase to practice calculating both area and perimeter. Real world problems encourage learners to discover that we use math each and every day.
