Looking for a fun way to teach ratios, scale, and proportion? Try this out! My kids loved it!
Students will be able to use their knowledge of ratios and proportions in order to create an accurate scale drawing of the United States.
Students will use research skills to collectively gather real-life ratio information on each state.
You will be working together as a class to try to create an accurate scale drawing of the United States! Each person (or set of partners) will be assigned 2-3 states. You will be given some time to look up interesting ratios related to your states, and you will be challenged to accurately use a scale proportion to enlarge the picture of your states. If everyone in the class does it correctly, we should be able to create one LARGE and accurate representation of the United States by putting our scale drawings together like a giant puzzle.
Tentative Outline of our Work Schedule
- Partner selection
- State assignments
- Individual state ratio research
- Citing sources
- Investigating how your original picture gridlines are set up
- Using scale proportion to create an enlarged grid for your new scale drawing and beginning the drawing process
- Measuring, cutting, and creating gridlines on your enlarged paper
- Accurately drawing and coloring your state
- Putting together the final product
- Sharing ratio information
- Individual reflection and self-evaluation
My students are highly motivated to do this project. It incorporates research skills, team work, careful calculations, critical thinking, and problem solving!
This product includes:
A student guide with day by day instructions/checklists, grading rubric, original gridded drawings of the 48 contiguous United States, additional options for differentiation, ungridded drawings of the 48 contiguous United States, and teacher notes/suggestions for each day.
