• This spreadsheet allows you to see a visual representation of a fraction.
• Simply enter values for the numerator and denominator in the box provided (and press your "Enter" key after each). Then a circle graph will be generated that shows a picture of that fraction.
• Here are some things to try:
  • Leave the denominator the same, but change the numerator. What happens when you do this? Why? From what you have seen, what does the numerator represent?
  • Next leave the numerator the same, but change the denominator. What happens when you do this? Why? From what you have seen, what does the denominator represent?

Standards (Ohio Academic Content Standards):

• Math - Grade 1 - Number, Number Sense and Operations
  • #9 - Represent commonly used fractions using words and physical models for halves, thirds and fourths, recognizing fractions are represented by equal size parts of a whole and of a set of objects.
• Math - Grade 2 - Number, Number Sense and Operations
  • #5 - Represent fractions (halves, thirds, fourths, sixths and eighths), using words, numerals and physical models. For example:
    a. Recognize that a fractional part can mean different amounts depending on the original quantity.
    b. Recognize that a fractional part of a rectangle does not have to be shaded with contiguous parts.
    c. Identify and illustrate parts of a whole and parts of sets of objects.
    d. Compare and order physical models of halves, thirds and fourths in relation to 0 and 1.
• Math - Grade 3 - Number, Number Sense and Operations
  • #5 - Represent fractions and mixed numbers using words, numerals and physical models.
• Math - Grade 4 - Number, Number Sense and Operations
  • #1 - Identify and generate equivalent forms of fractions and decimals. For example:
    a. Connect physical, verbal and symbolic representations of fractions, decimals and whole numbers; e.g., 1/2, 5/10, “five tenths,” 0.5, shaded rectangles with half, and five tenths.
    b. Understand and explain that ten tenths is the same as one whole in both fraction and decimal form.
