Here is really nice set of resources on scientific notation. Eighth and ninth graders explore the concept of multiplying and dividing in scientific notation. In this multiplying and dividing numbers in scientific notation...

Explore scientific notation in this mathematics instructional activity. Young mathematicians explore multiple representations of large number in scientific notation through the use of models, visual representation and expanded form. The...

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

Middle-school mathematicians identify the need for scientific notation. Learners convert large and small numbers into scientific notation. Students review the powers of ten and write them on the board in standard form and scientific...

Discuss scientific notation with this mathematics lesson. Middle schoolers predict which problem is bigger of two numbers. They analyze the problems by observing the powers of 10 in order to decide which is bigger. This appears to be an...

Expand your knowledge of exponents with an activity that promotes critical thinking and comparison skills. Middle and high schoolers compare numbers written in expanded and exponential form and explain their strategies for solving...

Ninth graders solve problems involving exponential functions. In this algebra lesson, 9th graders apply their knowledge of exponential properties to add, multiply, divide and subtract exponential functions. They perform these operations...

Order up a resource on comparing rational numbers. Scholars order fractions, decimals, and percents by converting to a single form. They conduct a cut-and-paste activity ordering three sets of rational numbers.

Scholars view the video, "Donald Duck in Mathmagic Land," and discuss examples in nature which have proportions of the golden ratio. They measure and record different body lengths from a worksheet and convert the ratios to equivalent...

Investigate simplifying rational expressions. Learners define rational expressions, review how numerators and denominators are polynomials and complete several problems using a checklist to ensure they don't skip any steps. Work can be...

Introduce your middle and high schoolers to the correct use of quotation marks. They identify examples of correct and incorrect quotations in magazines and edit a paragraph in groups. Use this lesson as a way to reinforce proofreading...

Middle schoolers use ratios and proportions to represent quantitative relationships as they investigate the concept of how percentages are used by designers. Students decorate the same room using three different percentages of colors.

Students demonstrate a comprehension of the properties, position, and motion of objects and materials, and of light, heat, electricity, and magnetism. They use materials to assemble an electric circuit and test materials, including...

Students investigate the property of rocks and how to distinguish among the different types. They explore the hardness of rocks and perform streak tests to determine mineral color. They classify rocks according to their properties.

Fourth graders complete a worksheet. As a whole class, 4th graders hear a lecture and complete a worksheet on factors, multiplicative inverses and reciprocals, finding the quotient of two fractions and the division of fractions to...

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..

Students are introduced to mixed expressions and complex fractions. They work through several problems with the instructor and then complete a worksheet.

Students compute minimum velocity, using square roots.
