Students use the Pythagorean Theorem to solve problems. In this geometry lesson plan, students solve for the distances by calculating the different parts of the shape of a two and three dimensional shape. They reason by analogy.

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...

Students pace a Gunther Chain, a measurement used by foresters to determine distance and area. They discuss that pacing is individualized depending on age, gender, etc. They practice to find an average pace. Teams estimate, pace and...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Tenth graders investigate the volume of a cylinder.  In this geometry instructional activity, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The instructional activity progresses...

Students explore the concept of quadrilaterals. In this quadrilaterals activity, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.

Sixth graders compute the surface area. In this surface area lesson students are given a set of problems to calculate. They compute the surface area of cubes and rectangular boxes.

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Learners differentiate distance and displacement. In this physics lesson, students use formulas to calculate for displacement. They draw vectors using the grid.

Students study the history of kites and their fundamental properties.  In this kites lesson plan students divide into teams and build and fly kites. 

Students explore various polygons and examine how shapes can be manipulated in a variety of ways. In this shape tool lesson, students identify geometric shapes in two dimensions. Students identify and draw one line of symmetry in a...

Pupils identify different polygons. In this geometry lesson, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.

Students find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson plan, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no...

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Students explore volume and surface area. In this math lesson, students fill boxes with cubes to identify the volume of the boxes. Students discuss area.

Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create quadrilaterals

Students measure the perimeter and area of their polygons. For this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Pupils solve real life situation using the Pythagorean Theorem. In this geometry instructional activity, students calculate the length, midpoint and slope of segments. They solve word problems using properties of square roots.
