13. Demonstrate that a unit fraction represents one part of an area model or length model of a whole that has been equally partitioned; explain that a numerator greater than one indicates the number of unit pieces represented by the fraction.

[MA2019] (3) 14 :
14. Interpret a fraction as a number on the number line; locate or represent fractions on a number line diagram.

a. Represent a unit fraction (1/b) on a number line by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts as specified by the denominator.

b. Represent a fraction (a/b) on a number line by marking off a lengths of size (1/b) from zero.

Description:

This is a free classroom resource from PBS.  Teachers will need to click on Procedure to access the full activity. 

There are three options for this lesson, depending on class needs and time available:

  1. Frame, Focus, and Reflection (view and discuss): students will watch segments from CyberChase that introduce or reinforce fraction concepts.
  2. Short hands-on activity: students will play a game with fractions.
  3. Project: students will explore fractions through rhythmic sequences.

Title: Retrieving 2/8 of the Healing Stone
URL: https://aptv.pbslearningmedia.org/resource/vtl07.math.number.fra.retrieve28/retrieving-28-of-the-healing-stone-cyberchase/
Description:

The CyberSquad must make an antidote to a virus that has infected MotherBoard. One of the ingredients in the antidote is 2/8 of a Healing Stone. Matt and Digit locate the stone and notice that it is divided into four sections. Because they need to divide the stone into eight equal pieces, they learn about equivalent fractions.
