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...

Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Learners use manipulatives to study shapes. They sort shapes and use correct geometric terminology to describe them. Students find real-life examples of 2 and 3 dimensional shapes, and classify figures in their classroom according to...

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...

Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

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...

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

Learners participate in a number of hands-on shape-related activities. They match and sort shapes by attribute, read books about shapes, complete shape art projects and explore and compare parts of shapes.

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Third graders investigate how and why scientists use classification. They discuss classification strategies using animals, and as a class fill in a flowchart with their responses. Next, in small groups they cut out a variety of shapes...

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...

Young scholars access the Library of Congress's collection of Broadsides (printed material with news, entertainment, advertisements, etc.) and explore their impact on events leading up to the Revolutionary War. They create a timeline...

Pupils describe, draw, and classify shapes. They use the internet to research the X-36 aircraft. Students identify the geometric shapes in the aircraft. They calculate the number of sides in an x-36.

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...

Pattern recognition is a skill often used in mathematics. Learners count and sort manipulatives, organize the data into a graph and answer questions about the information displayed. They collect the objects to be used and create patterns...

Students play a bingo game to classify 3 dimensional shapes. In this 3 dimensional shapes lesson plan, students identify, describe, and classify shapes by playing a bingo game.

Young scholars practice skills used in scientific investigation while studying the three main types of galaxies. Students identify Earth as part of Milky Way galaxy, the parts of galaxies, and the types of galaxies, as well as classify...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

Third graders listen to a talk on phase transitions and view three demonstrations. In this phases of matter lesson, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of phase...

First graders identify details that make reading and writing more interesting. They classify events, people, places, and things and attach specific characteristics to each one. Everyone generates describing words on a worksheet that's...

Young learners listen to a read aloud of Gail Gibbons book, Apples and the story A Red House With No Windows and No Doors. They compare characteristics of a number of kinds of apples, graph them and create a apple print picture. Learners...

Students, after exploring and analyzing diagrammatic and taxonomic keys and their association to marine sciences, identify and classify objects and organisms based on visual attributes/characteristics. They research and create their own...
