Mathematical Standards

3.NF.A
Develop understanding of fractions as numbers. (3.NF.A.1, 3.NF.A.2. 3.NF.A.3)
3.G.A
Reason with shapes and their attributes. (3.G.A.2)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.

Students represent fractions using circle pieces, fraction strips, drawings, number lines, words, and symbols. Students make connections between these representations as well.

Content in this Lesson

  • Representing fractions using manipulatives, number lines, and drawings [E1].
  • Representing fractions using words and numbers [E2].
  • Recognizing that fractional parts of a unit whole may be different shapes but must be the same size [E3].
  • Identifying a fractional part of a set [E5].
  • Partitioning circles and strips into given fractions [E6].
  • Identifying the unit whole when given a fractional part of a whole [E7].
  • Making connections among representations of fractions including symbols, words, drawings, fraction strips, and number lines [E8].
  • Comparing fraction models [E10].
