Students complete a unit of lessons on computing area and volume. They play a Jeopardy game of basic area formulas, calculate surface area of shapes, develop a Powerpoint presentation, and conduct a simulation of finding the surface area of a spa.
Learners explore the concepts of voting and the variety of voting methods. In this voting system lesson plan, students investigate the advantages and disadvantages of each method. Learners collect data and record combination patterns on activity sheets.
Educators can use music lessons that show students how to learn about rhythm in a fun and exciting way.
Fifth graders use prime factoration and the use of prime and composite numbers.
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.
Students 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.
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.
Middle schoolers engage in a clever lesson that combines meteorology with mathematical thinking. They use integers in relation to high and low temperatures that they record. They use a spreadsheet of weather data, a computer, and gain valuable practice in using integers.
