The above lesson includes audio (so remember to switch on your speakers). Use the play/ pause button if you need to stop and start the lesson. This fraction lesson is number 3 of 6 and looks at common denominators and how they are very useful when adding, subtracting, or comparing fractions.
The Fractions Lesson explained above is aligned with the standard 4NF02 from the Common Core Standards For Mathematics (see the shortened extract below). The resources below are also aligned to this standard.
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
