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.
