Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

In this 2-day instructional activity focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess...

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...

Students explore the concept of triangles.  For this triangles lesson, students are to propose a plan for a ramp at their school.  Students use the Pythagorean Theorem and trigonometry to determine the length, height, and angle...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Students create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be selected for...

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.
