Welcome to my math blog! The purpose of this blog is to help you stay informed about our learning and experiences that have taken place during our math class. I have also included links your child (and you) may want to use in order to supplement math learning in 5th grade.

Equivalent Fraction Notes

We took notes on equivalent fractions today and made a foldable to put into our journal.  You can watch the recording by following the above link.

Basically, we began by defining an equivalent fraction as fractions with the same value.  We discussed that we can create an equivalent fraction by either multiplying or dividing BOTH the numerator and denominator by the same number.

We worked a few examples of finding equivalent fractions using multiplication.  I tried to reinforce the idea of equivalence by explaining that we are working with a rectangle.  We break the rectangle into three parts and color two.  This is 2/3.  If we take that same rectangle and break it into six parts, four would now be colored (4/6 = 2/3).

We reinforced the use of the GCF (Greatest Common Factor) which we had done in class last week.

However, I also showed how to use factor trees to find the GCF and the simplest form of the fraction.  We will be practicing simplifying fractions using the factor trees tomorrow.

HOMEWORK:  Countdown 2.7

1. This is great! Do you, by chance, have the file for the example you placed in the foldable? If so, would you mind terribly making it available or even emailing it to nminera@latinpcs.org? I would LOVE to use this tomorrow instead of the guided notes I was going to give them.

2. Thank you for your kind words! I am so glad you found something useful!

I meant to put the link on there...

Also, if you are interested, I am attaching the link to the lesson I did this year to find the LCM and GCF using factor trees and venn diagrams. You might like the videos.
