 * Theme Essential Question **** : What do fractions mean? **
 * Essential Questions: **
 * How can I divide an area into equal parts?
 * How can I identify equivalent fractional parts?
 * How can I use fraction notation to record equivalencies?
 * How can I use mixed numbers to represent quantities greater than 1?
 * How can I use representations to combine fractions that sum to 1?
 * How can I use fraction notation to record equivalencies?
 * How can I use representations to combine fractions to equal other fractions?


 * Standards **
 * ** 3.NF.1 ** Develop understanding of fractions as numbers. Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity fromed by a parts of size 1/b.
 * ** 3.G.2 ** Reason with shapes and their attributes. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that shared attributes can define a a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
 * ** 3.NF.3a ** Understand two fractions as equivalent if they are the same size, or the same point on a number line.
 * ** 3.NF.3c ** Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
 * ** 3.NF.2a ** Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
 * ** 3.NF.2b ** Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.
 * ** 3.NF.3b ** Recognize and generate simple equivalent fractions, Explain why the fractions are equivalent, e.g., by using a visual fraction model.


 * Objectives **
 * Use fraction notation to record equivalencies.
 * Identify equivalent fractions.
 * Divide a group into equal parts and name the parts with fractions.
 * Use mixed numbers to represent quantities greater than 1.
 * Divide an area into equal parts.
 * Use representations to combine fractions that sum to 1.
 * Use representations to combine fractions to equal other fractions.
