Comparing Fractions Anchor Chart

Written by Donna Boucher

Donna has been a teacher, math instructional coach, interventionist, and curriculum coordinator. A frequent speaker at state and national conferences, she shares her love for math with a worldwide audience through her website, Math Coach’s Corner. Donna is also the co-author of Guided Math Workshop.

Recently, I published a series of posts describing the various strategies students can use for comparing fractions. While creating a common denominator is one of the strategies, it is often not necessary. For example, consider this pair of fractions:

Comparing Fractions Example
Do you really need to find a common denominator in order to compare these two fractions? I think not. The first fraction is clearly less than one-half, while the second is greater than one-half. Case closed. Comparing fractions using a benchmark of one-half is just one of the strategies students should have in their toolbox.

I have been working with my 4th graders on this skill, and I created an anchor chart for them to use as a reference when comparing fractions. Please, PLEASE remember that students need lots of concrete and pictorial experiences with fractions to be able to reason about the relative size of fractions, which is why I included visuals on the anchor chart. You can download a copy of the anchor chart here.

I wrote a series of posts about strategies for comparing fractions. Click here for the first in the series. Each post contains a link to the next post. You’ll be able to download free activities along the way!

    Thank you so much!! I read your series, and was hoping you had something to match in your tpt store. This is wonderful! You should consider making some full page posters for each comparing strategy.

    This is great, Donna! Thank you.
    I have a question… Do you know of any prominent articles about combining rote learning and strategy based instruction, and the importance of strategies?
    Thank you,
    Ali.

      I’m sorry I can’t point you to one article. I have lots of books that cite a great deal of research, however.

    Dear Donna,

    I really appreciate your way of clarifying the concepts. Can you recommend me few of your books which I can consult to teach my students in India. I run a learning center here and I follow so much your examples and techniques and my students enjoy the same.

      Not to worry! Just enter your two-digit month, you the tab key to move to the day, and enter your two-digit day. So if your birthday is July 8, it would be 07, press the tab key, 08. Hope that helps!

    Any chance I can get a digital file of the graphic from the top, Strategies For Comparing Fractions? I would like to print a poster of it to hang in my class.
