Given the lines of symmetry in an equilateral triangle, your learners find where the pre-image vertices are mapped onto the new image. They explore the properties of equilateral triangles, the impact of reflections, and the...

Uncover the properties of translations through this exploratory lesson. Learners apply vectors to describe and verify transformations in the second installment of a series of 18. It provides multiple opportunities to practice this...

Challenge your class to use straight lines when estimating the length of a curve. An engaging interactive allows individuals to place line segments one after another along the arc. Learners determine that the more lines used, the better...

Start simple by using a shape-partitioning learning exercise. Scholars begin by segmenting basic shapes in halves and quarters. On the second page, they move on to more complex shapes, such as a heart and a cross, also partitioning them...

Here's a lesson that just might make your class squirm! Learn about segmented worms in a detailed PowerPoint presentation including the wriggly earthworms young scientists dig up in their backyards. Although seemingly simple creatures,...

Let's use math to solve an argument. Jon and Charlie are debating about who can run farther, but who is right? That's what your class will figure out as they apply their understanding of fractions to this real-life situation. A simple,...

It is easy to find the area of a triangle where the base and the height are given. But in this resource, it is up to your geometers to identify the base and height of the triangle. In fact, your pupils will learn that there are three...

Learners see application of construction techniques in a short but sophisticated problem. Combining the properties of inscribed triangles with tangent lines and radii makes a nice bridge between units, a way of using...

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

In this skills worksheet, students explain the Segment Addition Postulate, provide examples and counter examples and determine congruent line segments.  This one-page worksheet contains 11 multi-step problems.

Students graph and solve quadratic equations. In this functions lesson, students analyze a quadratic equation using three points on a curve to define the graph of a quadratic function. They find the vertex and intercepts of the graph.

In this grade 3 mixed math worksheet, 3rd graders complete 9 problems. They work with fractions, nets, line segments, elapsed time, and a data table. They draw the bar graph to go with the data, and practice mental multiplication.

In this geometry worksheet, 10th graders calculate the perimeter and area using the specific formula for that polygon. There are 5 questions with an answer key.

Mathematicians measure intersecting lines-and circles, and create chords. In this geometry lesson plan, students explore interrior and exterior chords created by tangent and secant lines. These segments can be inside the circleor outside...

In this contour integration worksheet, students evaluate an equation, sketch the contour and evaluate the integral. This two-page worksheet contains approximately eight problems.

Tenth graders construct a variety of geometric shapes and designs using a Mira, Clinometer and Geometry Flash Cards. They complete a worksheet.

In this midpoint worksheet, students solve 2 short answer problems. Students prove the midpoint of a segment using the definition of midpoint. Students given an example of using midpoint in everyday life.

In this reasoning with rules worksheet, learners solve and complete 12 different problems that include applying various rules to solve the equations given. First, they assume all segments are straight and state the rule used to solve...

In this polygons worksheet, 4th graders identify and name the 4 polygons drawn on the bottom of the worksheet and then draw a triangle, hexagon and a quadrilateral.

In this circles worksheet, high schoolers solve 10 multiple choice problems. Students use a diagram of a circle with tangent lines and segment bisectors to answer each question. High schoolers find unknown segment lengths using the given...

In this geometry worksheet, students construct perpendicular and parallel lines through a given points using a straightedge and a compass. There are 5 questions with an answer key.

In this grid activity, 5th graders use a grid map with coordinate points to answer six questions regarding distance between locations.

In this triangles worksheet, students identify the median, altitude, segment, angle bisector, perpendicular bisector and triangle midsegment of triangles.  They find the perimeter of triangles.  This three-page worksheet...

Your learners will construct the perpendicular bisector of a chord. They use Cabri Jr. to construct a circle and a perpendicular bisector of a chord. They then measure lengths of the chords and perpendicular bisectors. Learners use...
