Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

Pupils explore the midsegment of a triangle in the geometry lesson plan. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

After determining the volume of various drinking glasses , class members evaluate sample responses to the same task to identify errors in reasoning.

Students examine and discuss math vocabulary. They participate in various games involving the math vocabulary. Use this as a supplement.

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Students will explore frieze patterns. A frieze pattern is a mathematical concept to classify designs on two-dimensional surfaces, which are repetitive in one direction, based on the symmetries in the pattern. They will explore examples...

In this geometry worksheet, 10th graders respond to journal prompts related to prisms and classifying solid shapes.  The two page worksheet contains nine questions.  Answers are included. 

Students investigate measurement through the use of literature through this series of lessons.

Young scholars analyze satellite image data of Volcan Villarica. In this earth science lesson, students identify dangerous areas surrounding the volcano. They propose a new safe location for the town.

Second graders use a checklist to construct a Geo-Town map including a compass rose, a map key, and a paragraph about a walk around Geo-Town, using appropriate geometric and directional vocabulary to identify the two-dimensional figures...

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

Fourth graders create three-dimensional paper African masks. They analyze the geographic, political, economic, religious, and social structures of Africa. they discover that masks were worn for various ceremonies.

Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...

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 visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Third graders create a butterfly drawing that includes the elements of art and principles of design. They create artwork that can be made into ceramic tiles to be installed around the classroom doorways in our new addition.

Fifth graders classify triangles. In this triangle instructional activity, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Ninth graders investigate quadrilaterals.  In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas.  Additionally, students create various quadrilaterals given...

Learners relate Pi to a circle. In this circles lesson, students identify the different properties of two dimensional objects. They relate Pi to the circumference, diameter and area of a circle .

Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create quadrilaterals
