4.NS.3
Standard: 4.NS.3: Express whole numbers as fractions and recognize fractions that are equivalent to whole numbers. Name and write mixed numbers using
objects or pictures. Name and write mixed numbers as improper fractions using objects or pictures.
Teacher Background Information:

The way we write fractions with a top and a bottom number and a par between is a convention- an arbitrary agreement for how to represent fractions.
However, understanding of the convention can be clarified by giving explicit attention to the meaning of the numerator and the denominator as part of
iterating activities. Include sets that are more than one, but write them as simple or “improper” fractions and not as mixed numbers. Include at least
two pairs of sets with the same numerators such as 4/8 and 4/3. Likewise, include sets with the same denominators. After the class has counted and you
have written the fraction for at least six sets of fractional parts, pose the following questions:
 What does the denominator in a fraction tell us?
 What does the numerator in a fraction tell us?
Too often, students aren’t exposed to numbers greater than 1 (e.g., 5/2 of 4 ¼), so they find them confusing.

If you have counted fractional parts beyond a whole, your students already know how to write or . Ask students to use a model to illustrate these values

and find equivalent representations using wholes and fractions (mixed numbers). Using connecting cubes was the most effective way to help students see both
forms for recording fractions greater than 1. (Multilink cubes could also be used.)

The figure illustrates how to use connecting cubes. Students identify one cube as the unit fraction (5) for the problem ( 5 ). They count out 12 fifths and build
wholes. Conversely, they could start with the mixed number, build it, and find out how many total cubes (or fifths) were used. This procedure is an example of a
length model. Repeated experiences in building and solving these tasks will lead students to see a pattern of multiplication and division that closely resembles
the algorithm for moving between these two forms. Context can help students understand the equivalence of these two ways to record a fraction. (Van De
