Students calculate the area of different polygons. In this geometry lesson, students find the area for trapezoids, rhombuses and kites.

Students explore photovoltaic systems. In this alternative energy lesson, students calculate solar panel efficiency and convert devices to solar energy using photovoltaic cells.

Students trace the route of the historical event and measure the distance over which the people involved journeyed. A data sheet be constructed outlining the location of events, and the speed with which the journey occurred.

Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.

Young scholars determine the missing vertices of quadrilaterals. In this rectangles and trapezoids lesson, students examine the characteristics of quadrilaterals. They identify the missing vertices of a quadrilateral on a coordinate plane.

Tenth graders experiment with gravity and air pressure. For this geometry lesson, 10th graders build their own kits and fly it. They investigate the questions: what keeps a kite in the air and what are some important factors when flying...

Students differentiate between inductive and deductive reasoning. In this geometry instructional activity, students identify congruent figures and examine logos for congruency.

Middle schoolers work in groups to show understanding of the relationship between fractions, decimals, percentages, and the application of ratios and proportions. In this decimals, fractions, and percents lesson plan, students use real...

Middle schoolers find the cost of an outfit. In this percentages lesson, students look at ads, pick out an outfit, and find the sale price. They create a commercial and complete 4 included worksheets. 

Students explore the concept of stem and leaf plots.  In this stem and leaf plots lesson, students plot the 50 US states' capitals on a stem and leaf plot according to the first letter of each state.  Students compare...

Young scholars use the Nspire software to graph. In this algebra lesson, students graph quadratic equations using technology and graphs. They identify the maximum and minimum of each graph.

Here is a new twist on teaching the associative property of multiplication. The author of this presentation makes an analogy between the associative property and a couple getting married. The numbers, like people, are separate, but when...

Students discuss elements of word problems: key words, data, computation clues, and unnecessary information and use the four steps of problem solving to find a solution and check for reasonableness.

Challenge your class to use their understanding of the engineering design process to design and build a small-scale, off-road prototype for an assistive technology device. Teams select materials to build their scale models, and, using...

Magnetic resonance imaging, just how safe is it? The introduction to unit study of magnetic resonance imaging technology presents the grand challenge questions of how an MRI machine works, the risks involved, the physics involved,...
