Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

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...

Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

In this rounding money worksheet, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.

Students explore the concept of geometric symmetry. In this geometric symmetry lesson, students walk around their school and take pictures of objects that demonstrate symmetry. Students use Microsoft Paint to draw the lines of symmetry...

Learners identify parameters using a slider template. In this precalculus lesson plan, students relate a slider to a calculator. It provides the learners the opportunity to control the perimeter of the equations.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

Learners use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.

Students watch the teacher demonstrate on an overhead projector how to graph various equations before the students try them on their own. They start with pencil and paper; once they grasp the concept they move on to punching in the...

Seventh graders explore the planets using computers and other forms of electronic technology. They research data on two planets and compare the data. Students make conclusions regarding the size of their planets. They calculate how long...

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...

Fourth graders read Mary's problem and make sure that they examine it. After some discussion, let the class work on the problem in their groups. They then take turns in putting a picture of their arrangement on the board.

Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.
