Seventh graders participate in a lesson that is focused upon the concepts of classifying different angles and triangles. They practice classifying triangles according to its kind that includes types of angles, congruence, and vertices....

In this polygons worksheet, learners classify each polygon in as many was possible. Students then write polygon or not a polygon to classify each figure. Learners find the measure of the missing angles and complete two test prep...

In this polygons worksheet, learners classify each polygon in as many ways as possible. Students then write polygon or not a polygon to classify each figure and find the measure of the missing angles. Learners finish with one word problem.

Students investigate variation in bird beaks and the interrelationships of form and function by classifying birds with similar beak shapes, inferring about the possible bird foods based on beak shapes, and locating and identifying...

Students observe leaves. In this plant biology lesson, students examine leaves and classify them according to size, shape, and color. Students learn more about the leaves by visiting suggested websites.

Students manipulate puzzle pieces to make them fit into the correct spot. They also learn the shape and design of several shapes and classify and sort shapes.

Middle schoolers classify snowflake crystals using geometric descriptors. They hypothesize about the temperatures at which the snowflakes were formed using a temperature/shape chart. They collect and examine snowflakes before drawing and...

Add a little color to the universe. Learners recreate images of the galaxies using real data and Photoshop software. They display their images in a Hubble tuning fork diagram by classifying and categorizing their shapes.

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Students classify leaves by shape and margins and use them to create models of plant fossils. By using paper over a leaf, they simulate fossilization of organisms onto sedimentary rocks. Following instructions on worksheets, students...

Students research hurricanes on the Internet. In this hurricane lesson, students use the Internet to find out the basic shape of hurricane winds and classify three characteristics of hurricanes. Students then classify at least three...

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Learners identify, compare, and analyze shapes and numbers. In this analogies and comparison math lesson, students warm up by completing 4 worksheets to familiarize themselves with analogies. In small groups, learners are challenged to...

Learners analyze and classify sets of pictures using a mathematical classification system and create original works of Art Deco tiles using this new knowledge and four types of symmetry.

Students classify various hardware items using the attributes of the objects. In this classification lesson plan, students group objects based on their attributes and explain their classification key.

Learners recognize and demonstrate the patterning of numbers and objects in our environment. They create a pattern using geometric shapes and find a missing number in a sequence.

Students explore factors that control variation in human skin color and the implications of this information for human society. They understand that skin color is no longer considered a credible scientific standard by which to classify...

Students find and classify insects. They collect insects, study them with a hand lens and identify its body parts. Afterwards, they discus various types of insects and thier Orders such as beetles, butterflies and moths, grasshoppers, etc.

First graders examine seeds. In this Science lesson, 1st graders classify and dissect seeds. Students sprout their own seeds in the classroom.

The World of Living Things is the focus of this biology presentation. Students view a presentation which introduces them to cells, parts of cells, microorganisms, and simple vs. complex animals. They see that they are classified as a...

Learners classify mammals as carnivores or herbivores. They look at a set of pictures of animal skulls, observing the shape and size of the teeth, and identify herbivores and carnivores.

Learners identify and analyze land use changes over time with historic aerial photographs, and classify different land use into categories.

Third graders sort objects into those they think will float and those that will sink and test their predictions. They experiment with clay molding it into shapes that float. They place pennies in them until they sink. They test other...

Students use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...
