How it's taught now (probably not how you learned it)

Fraction strips, number lines, and area models make common denominators, multiplication, and division visible before rules are generalized.

A worked example

Add 2/3 and 1/4.

Twelfths are a common unit: 2/3 is 8/12 and 1/4 is 3/12.

Answer: 11/12

How many 3/4-cup portions fit in 3 cups?

Divide 3 by 3/4.

  1. Adding numerators and denominators separately.

  2. Assuming multiplication always makes a number bigger.

  3. Reversing what division means when asking how many fractions fit in a whole.
