Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Students learn about sorting and classifying objects by size while reading Eric Carle's "The Grouchy Ladybug". In this sorting and classifying lesson, students first listen to and interact with the story. They then look at cut-outs of...

Students view a video and discuss different kinds of feet found in the animal kingdom. They make prints using paint, rubber stamps and their own feet and then measure and compare the tracks.

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

Students explore regular geometric shapes. In this shapes lesson, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.

Students identify, compare and classify the various shapes. In this shapes lesson, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher examples of shapes...

Students create leaf print banner for parents' night. They sort, classify, and pattern the leaves as they work.

Second graders collect data on different forms of transportation and create a bar graph or pictograph with the information.

Students explore geometric shapes. In this math lesson, students identify geometric and non-geometric shapes using the computer. Students research geometric shapes in art and architecture.

Let's study 2-D shapes! Young mathematicians compare and classify shapes according to attributes. They evaluate shape riddles and predict the shape being described. Here is the website where you can find the...

Shapes are all around us! Kindergartenrs identify shapes in their world and guess the shape being described. They participate in a shape hunt.

Students explore differents types of triangles and quadriaterals. In this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference between...

Fifth graders draw 2-D and 3-D shapes. They sketch and label geometric figures with correct terminology, then explore parallel and perpendicular lines. Pupils sort and classify shapes drawn.

Young scholars analyze data to make hypotheses and conclusions regarding the predator/prey relationship between moon snail and surf clams.

Students identify animals within a species by using their observation skills to record information, such as behavioral characteristics.

Students explore pyramids. In this math lesson, students discuss where they have seen examples of pyramids. Students classify pyramids as three-dimensional figures and identify their attributes.

Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle instructional activity, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...

Students explore geometry by drawing various shapes in class. In this triangle characteristics instructional activity, students identify the attributes that classify a shape as a triangle and practice using their bodies to create...

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.

Learners work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
