In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...

Learners investigate angles of polygons. In this geometry instructional activity, students identify the relationship between angles and the number of sides in a polygon. They differentiate between sumilarity anf congruence in angles and...

Students investigate special segments in triangles. In this geometry lesson, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.

Students calculate the lines of symmetry using polygons. In this geometry activity, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.

Students build and create using math. In this geometry lesson, students differentiate between congruent and similarity as they observe polygons. They create robots with different functions using properties of geometry.

In this math worksheet, students determine the name for each triangle according to its classification. Then they create a truss construction model.

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

Fifth graders examine patterns and relate to equations to solve math problems.  For this patterns lesson, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.

For this geometry worksheet, 10th graders solve problems that are based on the theorems associated with perpendicular and angle bisectors of a triangle.  An application on the coordinate plane is included.  The one page...

In this scales learning exercise, students find the weight of the shapes on the scale by comparing it to the other side, and make up their own problems. Students complete 5 sets of problems.

Middle schoolers identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Middle schoolers cut shapes out of...

For this online math worksheet, students consider a variety of scenarios which include elements of geometry and probability. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

Students are introduced to the basic trigonometric identities. Using a diagram, they discover why the parts of the unit circle as named as they are and use equations to finalize the Pythagorean trigonometric identities. They also review...

Young scholars decorate the congruent faces and edges of boxes in exactly the same way. They teach the terms "congruent," "faces," and "edges" to their parents.

Students design different shaped plots and determine the perimeter, area and shape of each. They compare the shapes that have the same area but may have different perimeters.

First graders investigate symmetry in patterns by utilizing unifix cubes.  In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at.  Students utilize...

Fifth graders describe patterns as relations and functions. In this patterning lesson plan, 5th graders analyze and continue patterns. Students understand how patterns relate to relations and functions.
