Ohio Standards. Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

OH.NNSO. Number, Number Sense and Operations: Students demonstrate number sense, including an understanding of number systems and operations and how they relate to one another. Students compute fluently and make reasonable estimates using paper and pencil, technology-supported and mental methods.

NNSO.5. Grade Level Indicator: Number and Number Systems: Represent fractions (halves, thirds, fourths, sixths and eighths), using words, numerals and physical models. For example:

NNSO.5.a. Recognize that a fractional part can mean different amounts depending on the original quantity.

NNSO.5.b. Recognize that a fractional part of a rectangle does not have to be shaded with contiguous parts.

NNSO.5.c. Identify and illustrate parts of a whole and parts of sets of objects.

NNSO.5.d. Compare and order physical models of halves, thirds and fourths in relation to 0 and 1.

NNSO.C. Represent commonly used fractions using words and physical models.

OH.PFA. Patterns, Functions and Algebra: Students use patterns, relations and functions to model, represent and analyze problem situations that involve variable quantities. Students analyze, model and solve problems using various representations such as tables, graphs and equations.

PFA.5. Grade Level Indicator: Use Algebraic Representations: Understand equivalence and extend the concept to situations involving symbols.
