1.)Prior to the lesson, print the attached worksheet and make copies for the students. Set up for the PowerPoint presentation. If you do not have a way of projecting the PowerPoint, you can print the slides and make transparencies.
2.)I would introduce this lesson by telling the students about a Missions Trip that I took to Honduras. I would have them brainstorm about things I would need to do to get ready for the trip. If they did not arrive at the fact that I would need to convert my money into their currency, I would offer that suggestion. I would show them the current exchange rate and lead them through an example of converting American dollars into Honduran Lempira. We could discuss the pitfalls of not knowing the exchange rate and how solving the equation to find the value of a lempira, would help them to spend their money more wisely while they were there. Having several Hispanic immigrants, I sometimes ask them to tell about getting used to our currency as opposed to the currency of their country. Another option would be to tell about an experience you have had with foreign travel or to have a 'Fantasy Trip' to wherever you choose. You can use the highlighted $$$$ below to access photos of foreign currency to show during your introduction. ( $$$$) A website containing photos of foreign currency.
3.)Explain to the students that they will be taking notes and working example problems during the presentation. Make sure that they have paper and writing instruments ready before the presentation begins.
4.)Begin the PowerPoint presentation. Pause and give the students time to work the problems. Also, have students copy down the examples and any other notes that will be helpful to them as they are solving the problems. Allow the students to present their answers as you go through the PowerPoint. One way that you might do this is to let them work them on an interactive board, of course, you could allow them to put their work on the whiteboard as well. Allow opportunities for student interaction and questions.
5.)If you happen to have computer access for your students, have them pull up an interactive worksheet for practice with immediate feedback. You may find the site by clicking the highlighted icon below. A variation of this would be for you to project the page for all to see and then allow different students to enter the solutions. ( icon) Practice page of literal equations.
6.)When finished with the PowerPoint, answer any remaining questions and then assign the worksheet. If there is not enough time to complete the worksheet 'Solving Literal Equations', assign it as homework and collect it the next day.
