Classification Teacher Resources

Sixth graders explore, analyze and study the history of classification systems and the scientific processes that influenced modern classification methods. They evaluate why classification and binomial nomenclature are necessary to the...

Students examine how many kinds of living things (e.g. plants and animals) can be sorted into groups in many ways using various features to decide which things belong to which group and that classification schemes vary with purpose.

High schoolers work with a set of objects to set up both quantitative and qualitative classification systems. As a group, students follow an example to design and complete two classification systems using a set of objects provided. ...

Students analyze the complexity of organism classifications based on certain criteria.  In this classifying organisms lesson students study taxonomy and gather information and leaves to do their own experiment on classification. 

In this classification worksheet, students pick the words that do not belong, make up the title for groups of words, and choose the title for the group of words. Students complete 3 activities.

Learners explore animal groups. For this animal science lesson, students use pictures from magazines and classify the animals into five categories. Learners share why they categorized the animals the way they did.

Tenth graders explain how organisms are classified according to similarities. In this biology lesson, 10th graders research on five different organisms of their choice. They prepare a report and presentation about them which they share...

Explorers of the environment construct a dichotomous key for a variety of organisms and design a key to classify Galapagos animals based on descriptions and images. The lesson includes a link to an animal gallery and the worksheet for...

Students create classification system for Arctic-dwelling animals, the Arctic hare in particular.

Students create a dichotomous key. In this categorizing lesson, students create a dichotomous key for different types of cereal. Students classify the cereal into groups such as flakes and cereal with holes. Students discuss their...

For this animal classification worksheet, students read for information and comprehension. In this fill in the blank and multiple choice worksheet, students answer five questions.

Third graders practice using classification techniques to identify local trees.  In this plant life instructional activity, 3rd graders discuss how trees differ from other plants and what characteristics are unique to trees alone....

Scientists use morphological, physiological, and molecular information to continually revise organism classification. Scholars observe and learn about 20 shells. Then, they work to sort and classify the shells, building a taxonomy based...

Did you know scientists identify more than 13 billion species of organisms, and they discover more almost every day? An interesting presentation demonstrates how scientists keep track of so many species. It also shows how they...

Make a game of angle classification. Using the direction of the pool ball, scholars determine the measure of the created angles. They work to create and classify different types of angles throughout an engaging interactive.

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Classify this resource into the "Use" pile. Scholars use an interactive coordinate plane to plot polygons given coordinates for the vertices. They use properties to classify each polygon and answer a few challenge questions regarding the...

In this classification of triangles learning exercise, 10th graders identify and complete 8 different problems that include determining the measurement and perimeter of various types of triangles. First, they color all right, acute, and...

Seventh graders work together to develop a leaf classification system. In groups, they are given a set of leaves and sort them based on their characteristics. They share their new classification system with the class and answer any...

After completing a unit on animal classification and attending a field trip students e-mail a trusted adult with some information about animal classification. They detail what they have learned about classifications of animals, insects...

Eighth graders create a classification system of the planets and give a written rational for their choice of categories.  In this investigative lesson plan students participate in an activity that helps them to explore classification.

In this classification worksheet, students describe the difference between Homo erectus and Homo sapiens. Then they define taxonomy and explain what was wrong with Aristotle's method of classification. Students also describe their...

In this classification worksheet, students will look at how biological classification began and how scientific names are used in biology. Students will use a table showing the classification of four organisms to answer 10 short answer...

Young scholars place organisms into the correct classification and justify their reasoning. They must include all objects and have a reason for their decisions.
