Mathematical Activities Using Exponents

If a variable x is raised to the power of variable y, y is called the exponent and the expression can be solved by multiplying x to itself y times. There are various laws of exponents that can be used to solve algebraic equations with exponents. Interactive classroom activities can be used to teach the concept of an exponent.
  1. Negative and Positive Exponents

    • Ask students to calculate different positive exponents of 10. Have them add a zero to the number as the positive exponent is increased. For example, 10 raised to the power of 2 is 100, which adds one zero to the number 10. Ask students to calculate the negative exponents of 10 by moving the decimal point to the left. For example, 10 raised to the power of "-2" is 0.01, and the decimal point has been moved twice to the left of the 1 in 10.

    Multiplying Operations with Exponents

    • Create worksheets for multiplication operations with exponents. Provide students with an example of the exponent multiplication property. For example, (2^2)*(2^3) = 2^(2+3) = 2^5. Ask students to multiply out (2^2) and (2^3) and multiply the final answers to each other. Now, ask them to verify that their answers match the value of (2^5). Set up the worksheets with a set of unsolved exponent multiplication problems and have students fill them out.

    Division Operations with Exponents

    • Teach students the division property of exponents. For example, (2^3)/(2^2) = 2^(3-2) = 2. Divide students into two teams. Write out 10 exponent division problems on the board. Have one person from each team come up to the board and solve the same problem. The person that completes the problem correctly gets one point. The team with the most points wins.

    Online Interactive Timed Tests

    • Create a series of timed online quizzes with exponent arithmetic questions. Ask students to complete specific quizzes based on their level of difficulty. Have them move on to quizzes with increasing levels of difficulty as they develop their skills further. Set up structured learning goals so students have a clear idea of how quickly they should be progressing.
