Students practice figuring out how items have been sorted. They also sort buttons in small cooperative groups. They color and sort their own paper buttons and then give their button sort to another student to see if he or she can figure...

Young scholars manipulate negative and positive numbers. In this integers lesson, students move through three activities exploring negative and positive whole numbers. A number line, cardboard function representation, and solving...

Students investigate the graphs of six trigonometric functions. They discover how changes in the equation of the basic function affect the graph of the function.

Eighth graders resolve vector problems without the knowledge of math.  In this vectors lesson students with poor math skills get a chance of passing the course. 

Students find the vertex, directrix, and focus of a parabola. They graph parabolic functions and solve application problems involving parabalas.

Students find the vertex, directrix, and focus of a parabola and graph parabolic functions. They solve problems involving parabolas after a demonstration lesson by the teacher.

Pupils participate in probability experiments and simulations while modeling and solving problems. They examine how to use the random number generator on a graphing calculator using examples from their local hockey teams.

Students write letters to town officials and local businesses asking for favorite dessert recipes. They tabulate their responses in a spreadsheet. Students turn their survey results into colorful graphs.

Students explore modular arithmetic involving base eight. They participate in an activity where society functions around the numbers one through eight. Students explain how life will operate with only these numbers.

Tenth graders explore the concept of spreadsheets. They create a simple spreadsheet and chart from given data. Students perform basic formatting procedures on their chart. They use spreadsheet functions to perform calculations.

Second graders observe some everyday common objects in order to attempt to learn about simple systems and how they fit together. They observe small details in order to identify the parts of a whole design.

Students analyze data and identify the mean. In this probability lesson, students log data in the TI and construct scatter plots from the data. They identify properties of a scatterplot.

Students examine and identify common insects. They observe these insects in their environment and keep track of how many they see. They use magnifying glasses and special hats to get into the role of an inspector.

Learners 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

Learners investigate chords and make predictions. In this geometry lesson, students graph circles and calculate the measurement of each chord. They perform the calculations and make conjectures.

Students examine spending and earning, and calculate change up to a dollar. They view and participate in demonstrations of earning and spending math problems, complete a worksheet, and play a game in pairs that simulates banking.

Learners calculate percent increases (or percent decreases) for the top 25 companies in terms of advertising dollars spent during a year.
