      TEKS 3.6E: Decomposing Figures into Equal Parts

      • Equal Shares of an Identical Whole

        About this lesson

        Learning Target: I can determine equal shares of identical wholes.

        Focuses On:

        • Understanding fractions must come from an identical whole
        • Fractional pieces must be equal in size

        Builds On:

        2.3B:

        Explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part

        Next Level:

        While there is not a direct correlation, this lesson continues to build the foundational understanding of fractions.

        Read More:

        This lesson is designed to support student understanding that fractional pieces must be equal in size and come from an identical whole.


        The two instructional blocks in this lesson focus on an identical whole and same size, different shape shares.


        In the first instructional block, students examine models to determine if they represent equal shares of an identical whole.


        The second instructional block focuses on equal shares of an identical whole that do not look the same but represent the same fraction.


        Scaffolds and supports such as models and pictorial representations are intentionally built throughout the lesson to support conceptual learning.
