:

Computation

Evaluate arithmetic expressions that include an exponent.

1:

Understand that an exponent indicated the number of times that a base is multiplied by itself.

2:

Write the expanded format for a given exponent (repeating multiplication equation that is equivalent to a given exponent).

3:

Write an exponent that is equivalent to the expanded format (a repeating multiplication equation).

4:

Evaluate expressions containing positive exponents.

8th

Vocabulary:

Exponent, Base Number, Power

Activities:

• Discussed and reviewed previously learned skills and knowledge on exponents from Order of Operations lessons.
• Learned that the value or answer of an exponential expression is called the "power" although "power" and "exponent" are sometimes used interchangeably ny some.
• Wrote a given exponential expression in expanded form.
• Wrote a repeated multiplication expression as an exponential term.
• Solved for the powers using repeated multiplication, being diligent about calculations as each answer is built on in the next steps.

Home Exploration

Challenge Problem:

Complete the table by filling out the exponent, expanded form, and/or power where missing.

Guiding Questions:

What is the base number and exponent of this problem?

What does the exponent tell you?

For problems where only the power is given, I noticed that the number ends in 5. What number do you think we could use as the base so that would give us a 5 in the ones place?
