Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

If there is a conditional statement, then there is a hypothesis and conclusion. Pupils learn how to identify the parts of conditional statements. Class members continue to work with conditional statements and rewrite them in their many...

Which deal is best? Learners determine which of two companies has the best deal for a particular number of shirts. They begin by creating a table and equations containing each company's pricing structure....

Learners explore the concept of translations. In this translations lesson, students discuss similarities and differences between images and pre-images. Learners apply translations to coordinates of figures. Students use patty paper to...

In this reflection, translation and rotation activity, learners determine which of these things have been done to s set of figures. A reference web site is given for additional activities.

In this reflection, rotation and translation worksheet, students determine which has been done to a set of 6 figures. A reference web site is given for additional activities.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Fifth graders explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practicing the new skills. Students...

Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Learners explore reflections on a coordinate plane in this lesson. They trace their hand on a grid, determine the coordinates of each point, and create a scatter plot of their points. Pupils use this information to investigate aspect...

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Middle schoolers explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Middle schoolers collaborate in graphing additional functions.

First graders, exploring lines of symmetry, follow directions to create a symmetrical snowflake from their own homemade icing. As a class, they discuss lines of symmetry and determine if specific shapes are symmetrical. After the lesson,...

Students become familiar with drawing segments and points. They understand how perspective drawing differs from three dimensional sketching. They demonstrate three dimensional and perspective drawing.

Slow and steady wins the race? In the assessment task, scholars calculate the rates at which different snails travel in order to find the fastest snail. Hopefully, your class will move much more quickly in finishing the task!

Students will explore frieze patterns. A frieze pattern is a mathematical concept to classify designs on two-dimensional surfaces, which are repetitive in one direction, based on the symmetries in the pattern. They will explore examples...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Students identify, compare, and analyze shapes and numbers. In this analogies and comparison math lesson, students warm up by completing 4 worksheets to familiarize themselves with analogies. In small groups, students are challenged to...

Young scholars use computer applets to demonstrate three dimensional coordinate planes. In this coordinate planes lesson plan, students play a coordinate game and a maze game.

Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

Young scholars scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go...
