Students draw a chart (included in the lesson plan) to use with their investigation. They review terminology of triangles and receive toothpicks to use in the lesson plan. Beginning with three toothpicks, students form a triangle. They...

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of...

In this angles and parallel lines worksheet, 10th graders solve 27 different variations of angle types and parallel lines. They name a linear pair, a pair of vertical angles, a pair of complementary angles, and a pair of supplementary...

In this measuring angles worksheet, students measure a set of angles, then check the appropriate measure and name of each. A reference web site is given for additional activities.

Here's an algebra II activity that strives to make the concept of a radian less abstract and more conceptual. It takes a hands-on approach to exploring the idea of a radian and allows individuals to develop a definition of a...

Students study geometric shapes and practice naming them properly. In this geometry lesson plan, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

Learners demonstrate and understanding of the three types of angles using triangles and quadrilaterals. In this angles lesson plan, students learn about acute, obtuse and right angles. They use cut-outs to find the areas of triangles and...

In this alkanes and conformation worksheet, students name 10 different alkanes, they write the structural formulas for 4 alkanes, and they write Newman projections for 2-methylbutane. They also write structure of stable conformations for...

Looking for a versatile worksheet on organic chemistry? If so, you might consider this resource. This resource asks learners to identify organic molecules, match terms with their definitions, determine bond angles and hybridization of...

Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

Are your geometry whizzes learning about angles and shapes? This online instructional activity gives 10 multiple choice questions based on images and word problems. Concepts include deducting angle degree, classifying shapes, and...

In this recognizing geometric figures learning exercise, students read descriptions, draw, label, and write the names and symbols for basic geometric figures. Students solve thirteen problems.

This five-page exam was designed for a biochemistry and organic chemistry course. It covers the molecular geometry and properties of organic comounds. Test takers identify compounds, functional groups, and isomers. They draw Lewis...

In this reflection worksheet, students will review the law of reflection and label a diagram with its angle of incidence and angle of reflection. Then students will compare different mirror surfaces as convex or concave. This worksheet...

If you need a straightforward and comprehensive organic chemistry exam, check this one out. Chemistry pupils identify functional groups in molecule diagrams, draw a Lewis structure, fill in a table about molecular shape, predict boiling...

Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

Sixth graders estimate angle measures and angle theroms. In this online interactive geometry activity, 6th graders review types of angles, investigate angle theroms, and explore nonadjacent angles.

In this geometry worksheet, 10th graders determine if the given point is in the exterior, interior, or on the given angle.  The one page worksheet contains eight problems.  Answer key is provided. 

Learners investigate the special properties of an altitude, a median, and an angle bisector and explore how these special segments divide the area of a triangle. The dynamic nature of Cabri Jr. allows pupils to form and verify conjectures.

Rays and angles and Star Wars? It sounds strange, but it's actually a fun game to help fourth graders get good at measuring and identifying angles and rays with a protractor. Each pair of children chooses which Star Wars character they'd...
