Students find missing angles and sides of triangles. In this geometry lesson, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Eighth graders explore the coordinate system. They identify the x and y-axis, parts of the coordinate plane, and discuss the process of plotting points. To emphasize the process of plotting points, 8th graders play an ordered pair...

In this Archimedes worksheet, students complete and respond to 4 different problems related to different triangles. First, they find the midpoint of each side of a given triangle. Then, students connect the midpoints with the opposite...

Upper graders explore the Fibonacci sequence. They examine the characteristics of the Fibonacci sequence, list the properties of the sequence and determine how it connects to Pythagorean Triples. Related thinking questions are included.

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate...

In this angle learning exercise, students first draw a set of intersecting lines, then use a protractor to complete a set of instructions about angles and answer related questions. Answers included on page 2.

Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

Young scholars develop locomotor movements. In this dance movement lesson, students identify lines and develop creativity while performing to "Cha Cha Slide". Young scholars discuss how to create dances and difficulty of movements. 

In this math worksheet, students find the vector parametric equation and symmetric equations for the line using two coordinate points.

In this geometry worksheet, students solve problems that are bimodal. They define properties of circles and triangles. There are 117 questions.

Young scholars discuss the concepts of reflection, rotation, and translation. For this rotation activity, students investigate rotations through examples on an overhead projector. No additional worksheet or student assignment is included.

Sixth graders are read The Way to Start a Day by Byrd Baylor or Bear Shadow by Frank Asch. They discuss how the sun affects their daily life, 6th graders are encouraged to think about the light we recieve from the sun and how man has...

In this systems of equations activity, learners solve each system of equations by graphing on a coordinate plane. Students identify the solution to the equations by the intersection of the two graphs. They also observe that parallel...

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Students solve systems of equations. For this algebra lesson, students use elimination and substitution to solve for the point of intersection. They use graphing to see where the two lines intersect.

For this Algebra I/Algebra II worksheet, students solve systems of linear inequalities by graphing the inequalities on a coordinate plane and determining the location of all ordered pairs that solve the system.  The three page...

Students solve problems using systems of equations. In this algebra activity, students find the point of intersection of two lines. They use the TI Calculator to graph and see the point of intersection.

In this spatial relations worksheet, students identify the number of triangles in a given figure, identify the number of cubes that a plane intersects, and determine the number of line segments in a given cube. This three-page worksheet...

In this math worksheet, pupils solve the problems that are correlated with the objectives. Each practice set has an in depth example.

Students explore a linear, a parabolic, and a log function.  In this Algebra II/Pre-calculus lesson students investigate the graph a line, a parabola, and a log function.  Students examine the three graphs as they compare and...

In this math worksheet, students explain the vector parametric equation for a line, scalar parametric equations, symmetric equations, and the implicit equation for a line.
