Your Task
We will be comparing prices in our two countries using ratios and proportions.
Classwork, Wednesday, Jan. 17
-
As a group, choose four items from your category (Wednesday, Jan. 17).
Homework due Monday, Jan. 22
- Each person will find a picture of an item in your category and be sure you know the price (due Monday, Jan. 22).
- Convert the price of your item in our currency to the currency of another country. Show all of your work and include an explanation for each step. Use the following values for the exchange rate.
Classwork, Monday, Jan. 22
- Create a slide in Paint showing the mathematics of converting the price of the item from one currency to another.
- As a group, create a BubbleShare presentation. Each person in the group will contribute three slides. The first slide will contain a picture of the item and the price. The second slide will be the Paint slide that shows the mathematics of converting the currency. The third slide will give the price in Canadian dollars and American dollars. Each member of the group will post their slides to the same presentation. Please tag your pictures and images Alatoba07.
Post your presentation to the wiki page for your group. Links to the group pages are listed below.

I am hesitant to have some of those currency links. They have calculators that will eliminate the problem. There are ways around this issue.

I put several just to keep what I found. I agree about the calculators. We might just want to post the conversion rate as of a certain date.

I can get an image to that effect and paste it in.

I changed the dates. I think this is the earliest deadlines I can meet. We can make them later if necessary.
Jan. 22 is a big day for our school. We are working toward becoming and IB school, and our consultant is coming to visit that day to determine how we are doing. I think this activity would be a wonderful one to do while she is there, if it goes well.
I could also do it earlier (maybe Friday) but that doesn't give them a weekend to get their pictures. What do you think?
One other thing...our technology work is supposed to follow the IB Design Cycle. I will email my information on that to you. I think this project is perfect, but I need to double check to make sure.

As you can see, I made my bubbleshare presentation. It is not beautiful, but it is done. I obviously made the text too small, but that will keep the students from reading how I worked the problem! Was this what you had in mind?
