Students create a Hexaflexagon using a formula. In this calculus lesson, students apply the definition of delta epsilon as it relates to limit to create a shape using creases. They relate the same rule to triangles and investigate angles.

Young scholars solve quadratic equations and identify functions. In this algebra lesson plan, students graph parabolas and identify properties describing the shape of the parabola. They find the vertex and rewrite the equation in...

Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.

Students apply the properties of a right triangle. In this triangle lesson, students describe and compare radians to degrees. They solve problems using the properties and ratios of a right triangle.

Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.

Students plan a trip.  In this trip planning lesson, students use a map to find where they would like to visit with a pretend family of 4. They get a specific amount of money and time and need to decide where they will stay and what...

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Students explore pentominoes in this activity. They build shapes as directed and color the tiles on their grid sheet.

In this area and volume worksheet, students find the lateral area, total area, and volume of given prisms. This two-page worksheet contains six multi-step problems. Answers to each problem are provided on page two.

In this area learning exercise, learners read and problem solve the area of 8 triangles. Students show their work on each problem on the learning exercise.

In this parallax effect worksheet, students observe 2 photographs taken of an active area of the sun by 2 STEREO satellites and 1 photograph taken of the same active area of the sun by the SOHO satellite. Students observe the shift in...

Students explore two-step linear equations.  In this middle school Pre-algebra instructional activity, students create and solve equations that describe how a person got to an end postion on a ruler by jumping.  After...

In this geometry worksheet, students solve right angle triangles using the Pythagorean Theorem. They calculate the area and sides of triangles and circles. There are 52 questions total.

Students work with Ellipses in Algebra II. In this algebra lesson, students solve an equation with a radical expression. They graph ellipses and write an equation for them.

Students explore the different properties of conics. In this algebra lesson, students calculate the midpoint of a line, the distances between two points as they get ready to find the focus and directrix in eclipse and other conics. They...

 In this Integrated Algebra worksheet, students solve problems that reflect the topics covered during the course of work.  The answer key identifies each question by standard and topic.  The twenty-four page worksheet...

Third graders explore the idea of formulating a hypothesis and designing an experiment to test the hypothesis.

Students define area and perimeter. They demonstrate understanding of the concepts concretely, with manipulatives, and describe with words, their strategies and thought processes.

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

Students will use everyday items and speeds to describe the dimensions of a massive flood that occurred in the Pacific Northwest near the end of the last ice age.

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...

Learners are presented with the question: "Do longer legged people run faster than shorter legged people?" Students conduct an experiment, collect their data, create box and whisker plots using a computer and graphing program, and...

Third graders create polygons with perimeters of 30 centimeters, use the centimeter grid paper to determine the area of each shape, and organize the shapes to make generalizations from the patterns they see.

In this triangulation worksheet, learners solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...
