Ninth graders investigate quadrilaterals.  In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas.  Additionally, students create various quadrilaterals given...

Fifth graders classify triangles. For this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Students explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...

Young scholars determine the missing vertices of quadrilaterals. In this rectangles and trapezoids lesson, students examine the characteristics of quadrilaterals. They identify the missing vertices of a quadrilateral on a coordinate plane.

Students find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane. They find the coordinates of missing vertices of squares and parallelograms.

Students calculate the area under a curve. In this calculus lesson, students integrate the function to find the area under the curve. They use the Ti to create a visual of the graph.

Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.

Young scholars identify and interpret the function, usefulness or utitlity, form, beauty or aesthetics, and meaning, context or story, of objects and how they learn new skills and make things that they learn traditionally, by observation...

Students apply definitions and theorems to verify special quadrilaterals using coordinate geometry. They apply the slope formula, the midpoint formula, and the distance formula to justify that a given quadrilateral is a parallelogram....

Students identify tangents, chords and secants. For this geometry lesson, students graph circles and identify angles created by secant lines, tangent lines and chords.

Learners find the volume of spheres. In this geometry lesson, students measure and derive the formula for each shape and solid. They use the correct terminology and units when solving these problems.

Sixth graders explore lines and angles. They create visual representations of lines, rays and angles by drawing them on paper and using a geoboard. On paper, 6th graders write a summary of the characteristics of their representations.

Students identify different properties of parallelograms. In this geometry lesson, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.

In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...

In this lines and strings worksheet, learners connect the letters along the outside of the box with string to create different kinds of lines. Students complete 4 problems.

Fourth graders create mandalas. In this mandala lesson, 4th graders look at these polygons in nature and man-made forms. They create their own by using tangrams.

Students perform translations and reflections. In this algebra lesson, students use the TI calculator to graph functions. They move the functions around on the coordinate plane using translation and reflection.

Students identify the measure of missing exterior angles. In this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Students apply what they have learned, from Eight Hands Round a Patchwork Alphabet, about how quilt blocks got their names by constructing and naming a quilt block pattern of their own using pattern blocks and pattern block paper.

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...
