Multiplication of Fractions (And January's Math Practice of the Month!)



In this "two-for-one" post, I am sharing some videos that I have been experimenting with to assist WCSU teachers as they plan their instruction around multiplication of fractions while simultaneously emphasizing CCSS Math Practice 3 (illustrated at left).

Math Practice 3 states that students must be able to construct viable arguments and critique the reasoning of others.

As you watch the videos, think about how students are being asked to present their arguments and analyze the reasoning of others.

What instructional practices foster growth of this practice?

About the lesson...

Typically, this is a fifth grade concept, however, if students do not have deep conceptual understanding that they can communicate using an area model, we need to "go back to square 1."  For seventh grade students, an excellent place to revisit this concept is between studying probability of compound events and ratios and proportions.
