Investigate the various properties of the number six with this elementary math lesson. From simple addition, subtraction, multiplication, and division problems to the creation of hexagonal tessellations, this lesson covers all aspects of...

Dedicate one or two class periods to creating a class glossary of geometry terms. Many geometry terms also appear in our every day vocabulary, but they have very different meanings. For example, the word gross in geometry is very...

Students explore number sense by solving consumer math problems. In this pattern identification instructional activity, students analyze a list of numerical and geometric patterns while predicting the future outcome. Students utilize...

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Students explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Students explore measurements by completing worksheets in class. In this geometry lesson, students identify the basic measurement units in both the English and metric systems. Students analyze 2 and 3 dimensional objects and identify...

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry lesson, 3rd graders create their own building designs and identify the geometric shapes that...

Students identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on each figure.

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this instructional activity. They make a set of tangrams and use them to...

Students build a scaled model of the solar system. In this space science lesson, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

Examine the relationship between time and geometry. A series of five lessons provides a grade-appropriate problem from elementary through high school. Each problem asks learners to compare the movement of the hands on a clock to an angle...

Shapes in art, shapes in stories, shapes in the environment, shapes all around. A multi-part lesson that includes looking at the artist Paul Klee's work, reading books about shapes, taking a walk in the neighborhood and identifying...

Lower elementary learners recognize solid shapes distributed for making fractions. Each individual uses a wheel and determine which part of a fraction is missing. This is a great lesson plan for your visual learners!

Have you ever wondered how circles and angles relate to each other? Read a passage about right angles, acute angles, and obtuse angles, and answer reading comprehension questions about the information you learn. 

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...

Students show the correlation between quadrilaterals, parallelograms, rectangles and squares.

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Third graders observe angles in their classroom and create an angle finder to represent them.In this angles lesson, 3rd graders classify angles as acute, obtuse, right or straight. Students find the differences and similarities in angles.

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging learners to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Young artists divide a piece of graph paper into sections using rectangles, squares, and triangles. They then fill each section with patterns of shape and color. Elementary graders describe how their patterns are organized. Secondary...
