In This Unit of Study…

Students will build upon their prior knowledge that fractions are equal parts of a whole, as well as their abilities to create and identify fractions of halves, thirds, and fourths. Students will extend their knowledge base to fractions with denominators of two (halves), three (thirds), four (fourths), five (fifths), six (sixths), eight (eighths), ten (tenths), and twelve (twelfths). Students should be able to represent and interpret unit fractions as part of a whole, part of a set, a point on a number line, or a visual model, as well as in fractional notation. Students will also represent and interpret fractions, including fractions greater than one, by composing and decomposing using unit fractions. In addition, students will read and write fractions by using standard form, numeral-word form, and word form.

B.E.S.T. Benchmarks:

  • MA.3.FR.1.1 Represent and interpret unit fractions in the form 1/n as the quantity formed by one part when a whole is partitioned into n equal parts.
  • MA.3.FR.1.2 Represent and interpret fractions, including fractions greater than one, in the form of m/n as the result of adding the unit fraction 1/? to itself ? times.
  • MA.3.FR.1.3 Read and write fractions, including fractions greater than one, using standard form, numeral-word form and word form.

Overarching Key Concepts:

  • Partition and iterate fractions using area models
  • Partition and iterate fractions using linear models
  • Represent and interpret fractions of set models
