Pupils use pattern blocks to create a figure that is described to them and establish a pattern based on the description of the geometric figure. In this pattern blocks lesson plan, students fill out shape and fraction worksheets.

Fourth graders identify lines of symmetry using reflections and then construct figures that have one or more lines of symmetry. In this symmetry lesson plan, 4th graders use sets of shapes, pattern blocks, a mirror, and more.

Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.

Learners explore the concept of translations. In this translations lesson, students discuss similarities and differences between images and pre-images. Learners apply translations to coordinates of figures. Students use patty paper to...

In this reflection, rotation and translation activity, students determine which has been done to a set of 6 figures. A reference web site is given for additional activities.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Fifth graders explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practicing the new skills. Students...

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Students explore the concept of fractal patterns. In this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

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 sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

In this rounding money worksheet, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.

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.

Students complete a chart (KWL) as a pre-assessment, study the history of tessellations (tilings), investigate the properties of tessellations, and make and evaluate photographs of "found tessellations" for a PowerPoint/HyperStudio...

Learners work together with a partnet to design a building. Using materials, they create the inside and outside of the structure along with works of art. They present their creation to the class and receive constructive criticism in return.

Students practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.

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.

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

Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Students find number patterns in the generation of several different types of fractals.
