High schoolers explore the concept of chemical formulas.  In this chemical formula lesson, students watch a video about balancing chemical equations.  High schoolers conduct an experiment using silver nitrate and sodium...

Students perform mathematical operations on complex numbers. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice performing operations on complex numbers.

Learners graph ordered pairs to model the relationship between numbers. After observing the patterns in ordered pairs, they describe the relationship, and create graphs from a data table. Students describe intervals in the graph, and...

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Students work together to build a simple gear train. They record their observations as it gains speed and how the gears rotate. They develop rules about gears based on these observations.

Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.

Students spend one month keeping track of the mileage and gasoline amounts they or their family has used. Information is entered into a spreadsheet to help calculate the average gas prices over time.

The purpose of this task is to see how well students students understand and reason with ratios. This task was adapted from problem #14 on the 2011 American Mathematics Competition (AMC) 8 Test. Aligns with 7.RP.A.3. The site provides a...
