- Students are provided with exponential expressions that are categorized as
Easier, Middle, Difficult, or Random. Students use the exponent rules to
simplify the expressions. Easy problems require the use of one exponent rule.
Difficult problems may require the use of up to four rules. Students can check
their answer or ask for a hint if they are unable to simplify on their own.
- Type of Material:
- This is an interactive Java applet.
- Recommended Uses:
- This material should be used as re-enforcement for the exponent rules.
- Technical Requirements:
- A JAVA 2 plug-in is required.
- Identify Major Learning Goals:
- The student will learn by practicing the following exponent rules: the product
rule, the quotient rule, the power rule, and the zero exponent rule.
- Target Student Population:
- Intermediate to College Algebra Students
- Prerequisite Knowledge or Skills:
- Students should understand what an exponent is and have an understanding of the
four rules mentioned above.
- Students can pick the desired skill level they feel comfortable with. Hints are
given when students click on the hint button. Very easy instructions to
- Although the quotient rule is used, most students are told a problem is not
considered simplified if it contains a negative exponent. Instructions should be
given to students explaining that they will have negative exponents in their
answers and therefore, may not be considered completely simplified.
- This is a great practice tool that reinforces the exponent rules. Students are
able to decide if they should add, subtract or multiply the powers by using the
rules. Feedback is given instantaneously and helpful hints are given when the
student is not successful.
- Again, students may be confused that they will have problems that have negative
exponents in their final answer.
- The program is easy to follow. The instructions are clear and precise.
