Fraction Fluency
(1st and 2nd Grades)
Embedded Files
Proficiency with fractions is an important foundation for learning more advanced mathematics. Fractions are a student’s first introduction to abstraction in mathematics and, as such, provide the best introduction to algebra in the elementary and middle school years. (Skip Fennel, NCTM)
Grade 1: Partitioning
Grade 1: Partitioning
1.G.A.3 requires students to partition circles and rectangles into equal parts and name the parts using phrases such as “one half” or “one fourth”.
This pictorial-to-language translation provides a base for understanding the part-to-whole relationship.
Students name the pieces with word labels rather than symbols.

Grade 2: Partitioning
From there, students in second grade (2.G.A.2 and 2.G.A.3) expand into partitioning thirds,
develop an understanding of how a whole can be represented as three thirds, four fourths, two halves, etc
and learn equal shares do not need to be the same shape.
