Young scholars engage in a hands-on experiment to determine how launch angles affect airflow around the wing of an aircraft. They view a series of photographs and read information describing the Wright Brothers' experiences. They...

High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...

Learners 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...

An informative lesson contains a brief explanation of how the sum of the angles of a triangle is a line. The lesson continues with determining the missing angle in a triangle, or solving for a variable. Using the sum of the...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

The interactive lesson featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...

Learners are given one angle measurement and determine either the corresponding supplementary or complementary angle measurement. A reference web site is given for additional activities.

In this angles worksheet, students estimate angles to within 15 degrees, then measure and name each. A reference web site is given for additional activities.

Young scholars use prior knowledge of angle and lines as they conduct an experiment with a rolling marble to determine the shape of a mystery object located under a metal pie tin.

A list of instructions for this exciting Geometry Jeopardy game is included on slide 2. There are a total of 25 clues and 5 categories, including: solids, triangles, lines, angles, and grab bag. Tip: Play this Jeopardy game with your...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

Learners examine a figure made up of different types of triangles and then determine whether each triangle is right, acute, or obtuse. Next, they color each type of triangle a different color. Finally, pupils answer three fill in the...

In this shapes and designs worksheet, 10th graders solve and complete 6 different types of problems. First, they fill in the first two columns of the table show with their shapes. Then, students measure the interior angles of each...

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

First graders explore two-dimensional shapes. Individually, children follow directions to draw shapes. Learners use shaving cream, geoboards, yarn, marshmallows, and toothpicks to create shapes. As a class, 1st graders brainstorm...

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Students analyze characteristics of geometric shapes. They find shapes in their environment, and communicate why it is like the shape of their choice and not like another shape.

In this online classifying angles worksheet, students work out the answers to sixteen math questions and fill in the boxes with their answers. Students check their answers online as they go and the computer calculates the overall score...

In this logical thinking with geometric shapes learning exercise, students write directions for transforming one shape into the next on a web. They write phrases such as "make two sides parallel" or "make all the sides the same length"...

Third graders analyze angles and determine if they are acute, right, or obtuse. In this angles instructional activity, 3rd graders study the definition and characteristics of each angle. Students then do a worksheet to identify the name...

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