Sharpen your pencil and grab a ruler, it's time to draw some quadrilaterals! Given the definition of a parallelogram, rectangle, and rhombus, learners draw examples and nonexamples of each figure. The three definitions are...

All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Second graders explore and analyze plane shapes. In this plane shapes lesson, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.

Fifth graders explore geometry by creating shapes with construction paper. For this shape characteristics lesson, 5th graders identify the different attributes that make up specific shapes and create them using construction paper,...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson plan would be an excellent choice...

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Students sort objects by shape, size and color. For this math and literacy sorting lesson, students listen to the book Freddy the Fish and the Squash that Goes Squish by Duke Christoffersen. Students work in small groups to sort...

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Students explore geometry by utilizing computer software. In this shape identification lesson plan, students define several geometric shapes by the characteristics that classify them. Students draw and cut out geometric shapes using...

Students observe a teacher demonstration o classifying matter by its physical properties of shape and size. After discussing the definition of matter, students describe the state of matter. They sing a song to the tune of "Bingo." In...

Students examine seeds from various plants. In this science lesson, students cut open fruits and vegetables in order to see the seeds. Students describe each type of seed and classify the seeds.

Excellent lesson plan! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

Written to examine seeds that grow in Kansas, you can adapt this lesson to anywhere you live. Learners sort a mixture of five different seeds to by any characteristic of their choice. When your budding scientists are exploring the life...

Here is a geology lesson which invites learners to explore a variety of rocks. They find rocks in the schoolyard and classify them according to size, color, and weight, then read the book Everybody Needs a Rock. Good lesson!

Students identify how to classify living things. They classify various concepts including family members, kinds of clothing, numbers, shapes, and vocabulary words. They discuss how to classify various concepts and classify pictures of...

Third graders investigate shapes in our world. In this geometry lesson plan, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and...

Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

First graders examine how to sort concrete objects by their attributes. In this sorting lesson, 1st graders listen to Gray Rabbit's Odd One Out by Alan Baker, and discuss the actions of the main character. They practice sorting objects...

Students collect and analyze pollen from different species of plants. In small groups, they classify pollen according to shape, size and physical characteristics. They draw the basic anatomy of flowering plants and create a dichotomous...

Young scholars use their math skills of sorting and classifying with materials they collect outdoors. In this early childhood math lesson, students participate in a treasure hunt to gather item in nature and categorize their finds.
