Ninth graders express mathematical properties through creation of advertising jingles.
Ninth graders explore mathematical properties through the use of an advertising jingle. They produce a commercial that is digitized and presented to the class. Students write a jingle that simplifies each property and helps classmates learn the properties.
Fifth graders discover the connections between algebra and geometry. With a focus on arrays and factors, they are introduced to multiplication. They develop an array for multiples of 2 through 10 and identify the factors of each row. They also discover patterns and complete a worksheet to end the lesson.
Pupils research Babylonian mathematics. They calculate simple surd numbers. Students find the fractional form of rational numbers expressed as decimals. They work with numbers in base 60.
Students study
Lower graders explore recursive patterns. They use a calculator to recognize, generate, and explore patterns during arithmetic explorations. The unit provides several assignments of an exploratory nature designed to assist in developing mathematical thinking and reasoning.
The class explores the concept of complex numbers on a website to generate their own Mandelbrot sets. They will practice performing operations with complex numbers and then to get a visual understanding, graph the absolute value of a complex number. Students take notes from a website about complex numbers.
Seventh graders develop a working understanding of percents. They collect examples of "real world" percents. An essay must be written indicating where the application of percent is used and conclude with a persuasive statement supporting the value of them.
Budding mathematicians complete activities to learn two-step functions to solve multiplication and division problems. They complete input and output charts to learn to problem solve using two-step functions. Then create their own flow charts to practice the function method.
Students map data on employment in wood products manufacturing in Oregon counties. For this Oregon forest lesson, students discover the percentage of people employed in the forest manufacturing industry. Students create a box and whisker plot for the data. Students color maps of Oregon based on the data. Students create a report about the economic status in Oregon forestry.
Students practice using GCF to simplify fractions. In this math lesson, students check their knowledge of GCF using the TI Explorer. This assignment provides step by step instructions to find the GCF on a TI.    
By working together, pairs of students will complete a Pi webquest. Using the internet, they examine the ways people in the Ancient Civilizations of Egypt, Babylonia and Greece used Pi. To end the lesson, they review the concepts of radius, diameter and circumference by creating a cartoon or poster to honor and publicize Pi.
Seventh graders calculate percentages, convert fractions to decimals, and decimals to fractions using information from a basketball game.
Elementary schoolers solve two-step equations and practice money concepts. They solve multi-step addition and subtraction contextual problems and apply money concepts to real life situations. Pupils use pictures and counters to help them solve the addition, subtraction, and monetary problems.
Students observe bird feeding and complete a tally and graphing activity for their observations. In this bird graphing lesson, students work in teams to observe bird feedings. Students complete a bird reporting sheet and collect data using a tallying method. Students compile the data into a bar graph to make comparisons and conclusions.
In this measurement worksheet, students problem solve by explaining how to measure gallons of water under certain circumstances.  They determine the weight of bottles and solve other proportion problems.  This two-page worksheet contains 4 multi-step problems.
Twelfth graders discuss centrifugal force, frictional force, and critical speed as it relates to the popular amusement park ride, the Gravitron.
Student identify the best way to measure. In this algebra lesson, young scholars measure using different units. They solve real life situations using measurements
Students explore the art of storytelling and stories from various cultures. Students experience Japanese and Chinese culture as well as Greek mythology. Students create and present their own Greek mythology topic to the class.
Students examine storytelling in a cross curricular unit. Language arts, social studies, science and math are all incorporated in this project as well as technology through the use of Hyperstudio.
