More about Fractions: Do the Work in Guided Math Groups

Posted on April 27, 2011. Filed under: Classroom environment, During the Guided Math Lesson, Elementary math, Guided math, Mathematical Proficiency | Tags: , , , , , , |


 The National Math Report said a great deal about fractions in elementary school.  Here are a few of the research highlights (p 17-18):

  • Pictorial representations, without sufficient emphasis on the nature of wholesmay be an obstacle
  • Number line representation may be more effective.
  • Words also seem to influence the mental representations that children form concerning fractions

 Recommendations

  • Focus on conceptual knowledge first
  • Procedural knowledge is equally important

Successful Interventions include:

  • the use of fraction names that demarcate parts and wholes,
  • the use of pictorial representations that are mapped onto the number line,
  • composite representations of fractions that are linked to representations of the number line.
  • Conceptual and procedural knowledge about fractions less than one do not necessarily transfer to fractions greater than one, and must be taught separately.

 Curriculum:

Spend time doing fractions and proportional reasoning… with the goal for students being one of learning rather than performance. However, there should be ample opportunity in the curriculum for accurate self-evaluation.

 What do you think of that?  Number lines are big here!  Pull out the number lines when you teach fractions…Also, self-evaluation keeps coming up.  Do you give your students time to self-evaluate?  How does that look across the grade levels?  Notice the emphasis on a learning rather than just performing.  We want students doing WITH understanding!

Happy Mathing,

Hi Dr. Nicki,
I can’t believe the Grade 4 Common Core Standards for fractions. It definitely redefines how educators should look at how to teach students about fractions. I used a ruler as a model when I taught Grade 5, and you are emphasizing use of the number line. The CCSM also makes mention of unit fractions as a bsis for understanding. Ideally, this should make middle school math and algebra teachers happy. Great post!! Thank you.
