I.        Topic Concept 1: Proportions
A)     ( 11/1/2011 – 11/23/2011) - Proportional Reasoning
a.       Can identify a proportion and manipulate it to find a missing (value, quantity, percent, missing value given two similar shapes, or unit – given a unit rate) represented as a variable
                                                               i.      Proportion: Two ratios set equivalent to each other
1.       Ratio: Comparison of two quantities that uses division
a.       Representation of ratios
                                                                                                                                       i.      a:b , a to b , a/b
                                                                                                                                     ii.      Manipulation of ratios
1.       Ratios can be represented as Equivalent Fractions
a.       Simplified ratios or fractions can be multiplied by any number to find an equivalent form of the same value represented by the ratio or fraction
2.       Equivalent: Comparison of two or more values that are equal, the same, or similar to each other
a.       The idea of a balance
b.      2 pencils in the left hand has the same value or quantity as two pencils in the right hand
3.       Cross Product: The product of the means and the product of the extremes. In the proportion, a/b = c/d , ad = bc The a and d represent the means, b and c represent the extremes.
a.       Recognition that cross products are equal
b.      If the cross products are not equal, then the ratios do not represent a proportion
    1. Can manipulate a proportion to find a missing value or quantity
                                                               i.      Solving for a variable, when a ratio is missing a value or quantity
1.       Variable: A letter or other symbol that can be replaced by any number or any other expression
a.       The missing quantity or symbol in the numerator or denominator of a given ratio that is set equivalent to each other
b.      Finding the value of the variable when using two ratios set equivalent to each other (using the idea that cross products are equal) – setting the expression of the (means) and( extremes) equal to each other
2.       Manipulating each expression of the equation on each side of the equal sign exactly the same way by combining like terms, and using inverse operation to each term by (multiplying, dividing, subtracting, or adding)
a.       Isolating the variable: to get the variable by itself on one side of the equation, creating a value or expression to the isolated variable
b.      Finding the percent of a ratio using part/whole is equal to %/100
c.       Finding a unit of two different units using the unit rate set equal to a similar ratio using the same units
d.      Finding the missing value or quantity of two equivalent ratios or fractions set equivalent to each other
    1. Can recognize portions of two similar shapes to find a missing value of a proportional shape
                                                               i.      This will be addressed later when we cover shapes
                                                             ii.      Will continue with the similarities of Equations and the setup of Proportions
