Unit 5 Understanding Fractions

In Unit 5 students will:

  • Understand a fraction 1/b as the quantity formed by 1 part when a whole is portioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. (Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.)
  • Understand a fraction as a number on the number line; represent fractions on line diagram. (Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.)
  • Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.
  • Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.

By the end of Unit 5 your child should be able to answer the following questions:

  •  How will unit fractions allow me to understand all fractions better?
  • How will fraction models help me understand the relationship between numerators and denominators?

 

 The following videos explain some of the topics covered in Unit 5.

  • Equal and Unequal Parts

  • Fraction of a Shape

  • Fractions of a Set

  • Numerators and Denominators

  • Fractions on a Number Line

  • Fractions on a Numberline
