 * Unit 2 – **** Understanding Percent **
 * By the end of this unit I should be able to:**

Big Idea- Decimals are an alternative representation to fractions, but one that allows for modeling, comparisons, and calculations that are consistent with whole numbers, because decimals extend the pattern of the base ten place value system.
 * 1) Be able to change a fraction to decimal and percent forms.
 * 2) Be able to change decimals to fraction and percent forms.
 * 3) Be able to change percents to decimal and fraction forms.
 * 4) Show these on a 100% grid or a 1% grid and be able to tell what is being shown on these grids.
 * 5) Find the percent if given a situation where you know a certain amount out of a total. ( Write the fraction and change to a percent)
 * 6) Find the percent of#. (Change to a decimal and multiply).
 * 7) Find the number (the whole) if given the percent and the part.
 * 8) Find the percent increase or decrease (= change/original x 100%)
 * 9) Find the discount, new selling price, sales tax (13%) and total cost of an item.
 * 10) Solve other word problems associated with percent.

Learning Goal  We are learning to represent proportions in different ways. This is important because some representations are better for specific contexts (fractions, decimals, percents)
