This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

In this properties of 3-D shapes worksheet, students identify shape, faces, edges, vertices, and right angles. In this fill in the blank worksheet, students answer thirty-six problems.

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...

Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to make a...

Students examine the properties of solids, liquids, and gasses. In this states of matter lesson, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state to...

A really useful resource contains 116 slides covering basic geometric concepts related to 2-D or plane shapes. Shape properties, translations, reflections, congruence, symmetry, and grid work are all laid out in a comprehensive and...

A collection of two lessons, kindergartners will identify two-dimensional shapes in solid shapes. They will develop basic knowledge of the components that make up a sphere, rectangular prism, pyramid, cylinder, cone, and cube. Young...

For this properties of quadrilaterals worksheet, learners use the properties of quadrilaterals to find the perimeter, angle measurement or length of a missing side of a given polygon. Examples and explanations of the properties are...

Here is a guide for your middle schoolers to use while you are providing a lecture on the basics of art. They use this activity to aid them as they take notes on the purpose of art, art elements, properties of art, and art principles....

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Students identify and categorize different polygons. In this polygons lesson plan, students research and identify properties of polygons,  identify different polygon shapes, and categorize different triangles and quadrilaterals.

Pupils 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...

Fifth graders explore shapes. They recognize and name two-dimensional and three-dimensional shapes. Pupils discuss the properties and criteria for each shape they find in real life and construct a Kid Pix project using pictures of the...

In this properties of 3-D shapes worksheet, students fill in a chart that describes 5 shapes such as a cube, a rectangular prism, and a cylinder. They tell if the shape is a prism, and how many faces, edges, and vertices it has.

For this faces of 3-D shapes worksheet, students determine the number of faces on 8 different 3-D shapes. . Students write twenty-eight answers telling the number of triangular, rectangular, hexagonal, and octagonal faces on the space...

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Do your learners know that letters of the alphabet have lines of symmetry? Well, some of them do. Scholars examine nine symmetrical letters and draw in the line of symmetry for each (one of them has two!). They also complete six letters...

In this area of shapes unit, upper graders participate in hands-on problem solving activities to find the formulas for the area of a parallelogram, a triangle, and a trapezoid. They manipulate the geoboard to explore relationships among...

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

If cubism were a religion, would you follow it? Lower-level tasks focus primarily on counting the number cubes in a structure and relating the number to surface area. As learners progress to higher-level tasks, isometric drawings and...

A great review of the structure and function of carbon-based molecules important to life, especially with relevance to humans. The chemistry behind the combination of polymers and the breakdown of bonds is covered. Valuable content...
