My Unit

The title of my unit is "It's Golden!". Students will interpret and use ratios in different contexts to show the relative sizes of two quantities, using appropriate notations. They will use proportions to solve problems. They will also use cross-multiplication as a method for solving proportions, understanding it as the multiplication of both sides of an equation by a multiplicative inverse
Essential Question:
What is change?
Unit Questions:
How can an understanding of ratios and rates help you solve proportions?
Why do you need to convert between fractions, decimals, and percents?
Content Questions:
How can you show that two ratios are equivalent?
How can you change a "rate" to a "unit rate"?
How do you solve a "proportion"?
How are "scale factors" used to create scale drawings?


  1. The practicality of this unit appeals to me. I am intrigued by "scale drawings" because that sounds like fun. I must admit, however, that I don't understand some of your terminology because I am an English person and not very "math savvy."

  2. I find the title a little confusing but the unit questions and content questions are understandable to me, even though "math" is not a language I speak.

  3. I too am unsure what your title is referring to in this case. The unit topic seems appropriate and the questions seem just fine. Perhaps another idea for an EQ might be "Does everything have order?" or "Can all questions be solved?" or "Does scale change everything?" depending on your focus.
