Compare and order fractions, including fractions greater than one, using models and strategies.


Remarks


Strategies include using benchmark fractions and common numerators and denominators. Typical benchmarks for comparing fractions are 0, 1⁄2, and 1. Fractions can also be compared by looking at numerators, such as when comparing 2⁄5 and 2⁄6. Since both fractions represent two parts of a whole, the size of the parts can be compared. Fifths are larger than sixths so 2⁄5 is greater than 2⁄6.

Test Item Specifications

    Item Type(s): This benchmark may be assessed using: MC item(s)
    Also assesses MA.3.A.2.2 Describe how the size of the fractional part is related to the number of equal-sized pieces in the whole.

    Clarification :

    Students will compare or order fractions using graphic representations or other strategies, such as benchmark fractions (0,1/10, 1/5, ¼, 1/3, 2/3, 3/4, and 1)

    Content Limits :
    Denominators of fractions must be 1 through 10, 12, or 16. 

    Items may include fractions and mixed numbers up to and including the whole number 5. 

    Items may include only the inequality symbols < and > .

    Stimulus Attributes :
    Items involving mixed numbers must include graphic representations.

    Fractions in items must have either the same denominators, the same numerators, graphical representations, or be easily compared to benchmark fractions, such as 0,1/10, 1/5, ¼, 1/3, 2/3, 3/4, and 1

    Response Attributes :
    Responses may include fractions, mixed numbers, or graphics.

    Responses should not be listed in numerical order when this would be a clue to the correct response.
