    Lesson Plan


    • Check a recent newspaper or the sites noted above for current foreign currency exchange rates. Write the exchange rates of Australian dollars to U.S. dollars on the board. For example, write
      1 Australian dollar = $0.5904 U.S. dollar 1 U.S. dollar = $1.6938 Australian dollars.
      Ask students to read and explain each equation. For younger students, you might round off the numbers.
      $1 (Australia) = $.59 (U.S.) $1 (U.S.) = $1.69 (Australia)
    • Give students various U.S. dollar amounts to convert to Australian dollars. Have students calculate the conversions. For example, ask "How many U.S. dollars are there in $5 Australian?" Students multiply 5 times the current rate for one U.S. dollar. Five times $0.5904 equals $2.952 U.S. dollars. Rounded, $5 Australian = $2.95 U.S. Ask "How many Australian dollars are in five U.S. dollars?" Students multiply 5 times the current rate for $1 Australian. Five times $1.6938 equals $8.469 Australian dollars. Rounded, five U.S. dollars are equal to about $8.47 Australian.


    Evaluate students' conversions.
