Does this truly provide a conceptual understanding of cross products?
Most of my sixth grade advanced math kids see it as a rule to memorize. So I set out to give a better conceptual understanding.
I tried the algebra approach but the concept was too abstract.
Then I related it to checking if the fractions are equivalent by finding common denominators using the existing denominators.
We’re beginning to get somewhere.
Then, again, we’re not.
I would love to learn how others approach this topic.
