This lesson teaches students about several of the rules regarding exponents. It uses a situation from Alice in Wonderland in which Alice's height is doubled or reduced by half depending on what she consumes to introduce negative exponents and the rules for dividing powers.

In CK-12 Middle School Math Concepts Grade 8, the learning content is …

In CK-12 Middle School Math Concepts Grade 8, the learning content is divided into concepts. Each concept is complete and whole providing focused learning on an indicated objective. Theme-based concepts provide students with experiences that integrate the content of each concept. Students are given opportunities to practice the skills of each concept through real-world situations, examples, guided practice and explore more practice. There are also video links provided to give students an audio/visual way of connecting with the content.

This lesson unit is intended to help you assess how well students working with square numbers are able to: choose an appropriate, systematic way to collect and organize data, examining the data for patterns; describe and explain findings clearly and effectively; generalize using numerical, geometrical, graphical and/or algebraic structure; and explain why certain results are possible/impossible, moving towards a proof.

Students will expand their basic knowledge of positive integer exponents and prove …

Students will expand their basic knowledge of positive integer exponents and prove the Laws of Exponents for any integer exponent. Next, students work with numbers in the form of an integer multiplied by a power of 10 to express how many times as much one is than the other. This leads into an explanation of scientific notation and continued work performing operations on numbers written in this form.

In Grade 8 Module 1, students expand their basic knowledge of positive integer exponents and prove the Laws of Exponents for any integer exponent. Next, students work with numbers in the form of an integer multiplied by a power of 10 to express how many times as much one is than the other. This leads into an explanation of scientific notation and continued work performing operations on numbers written in this form.

In this lesson, students will know how to take powers of powers. …

In this lesson, students will know how to take powers of powers. Students will know that when a product is raised to a power, each factor of the product is raised to that power. Students will write simplified, equivalent numeric and symbolic expressions using this new knowledge of powers.

In this lesson, students extend the previous laws of exponents to include …

In this lesson, students extend the previous laws of exponents to include all integer exponents. Students base symbolic proofs on concrete examples to show that (xb)a = xab is valid for all integer exponents.

In this lesson, students know the definition of a number raised to …

In this lesson, students know the definition of a number raised to a negative exponent. Students simplify and write equivalent expressions that contain negative exponents.

In this lesson, students know what it means for a number to …

In this lesson, students know what it means for a number to be raised to a power and how to represent the repeated multiplication symbolically. Students know the reason for some bases requiring parentheses.

In this lesson, students know that a number raised to the zeroth …

In this lesson, students know that a number raised to the zeroth power is equal to one. Students recognize the need for the definition to preserve the properties of exponents.

In this task, students must rationalize how a Ponzi email could make …

In this task, students must rationalize how a Ponzi email could make money or fall apart. Using their knowledge of exponential growth, the students can estimate the potential gains, but then are asked to think about why these schemes are illegal and tend to collapse.
