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

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Eleventh graders sort different types of functions including rational, periodic, exponential, polynomial, quadratic, logarithmic and linear using "function cards." The functions are displayed in multiple representations including...

Students classify polygons by name and shape. In this geometry lesson plan, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Third graders work in small groups to investigate how to sort a variety of items into groups and subgroups. They work on a class chart based on the activity which show how the items are classified based on commonalities. Upon completion...

Learners use a classification key from a provided worksheet to identify creatures. This task assesses student's abilities to interpret data, make decisions, identify, and classify.

In this flow chart worksheet, students learn to use flow charts for classification of numbers, geometric shapes and animals. Students follow the directions and fill out flow charts to work out 20 answers. This is an online activity that...

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Students investigate the usage of parallel and perpendicular shapes in the real world. In this geometry lesson, students investigate shapes for properties that are related to the real world. They relate all the properties of shape tot he...

Students explore polynomial functions.  In this Algebra II lesson, students explore graphs of polynomial functions as classify the functions as linear, quadratic, cubic, or quartic.  Students determine the regression equation...

First graders look for geometrical shapes in nature to help them appreciate the diversity of the natural environment.

Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

Students examine the shells, observing texture, shape, pattern and structure. They should come up with any system of grouping the shells they like, and classify the shells.

Students study and classify soil. In this soil science lesson, students classify soil by texture and size and study soil horizons. Students label the soil types with their specific soil horizon and learn about permafrost. Students...

Students research and create a slide show in order to classify clouds as transparent, translucent, or opaque.

Students identify and interpret various minerals and discover how to identify and classify them. They identify and discuss how people describe objects and how scientists describe objects. From there, students look at a set of common...

Students examine Hubble Deep Field images. In this galaxy classification lesson, students research galaxy classification. Students view and classify Hubble Deep field images of galaxies.

Fourth graders are divided into small groups and collect 4 objects from the playground. They take 5 to 10 minutes to classify their groups and discuss their findings including the terms "living" and "non-living". As a class they discuss...

Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.

Students classify sediments based on their physical characteristics, such as size, shape and color. They identify and describe rocks and minerals that are common to their region of the state.

Students study the design of snowflakes.  In this snow instructional activity, students discover the different shapes of a snowflake, and their similarities.  Students study snowflakes outside, then create their own with...
