A Slice of Number Line Pie (Gr. 3-5)

Description

Already knowing fractions of pizza and pie, students will "roll out" those models to connect them to the number line. In this lesson, students will use Dash to model fractions on a number line.

Objective

  • Connect circular fraction models to the number line
  • Understand that a unit fraction 1/b represents 1 section of a number line [0,1] that is broken into b sections
  • Model unit fractions on the number line
