One half of a whole and two of its four quarters occupy the same amount: 1/2 = 2/4. Multiply numerator and denominator by the same nonzero number to obtain an equivalent fraction: 1/2 = 3/6.

Changing only the numerator or only the denominator changes the value. Check equivalence using equal-sized wholes or the same position on a number line. Simplifying reverses scaling by dividing both numbers by a common factor.
Work through one example aloud before independent practice. To check 18 + 7 = 25, calculate 25 − 7. If a word problem asks about meters or coins, include that unit and check whether the answer fits the situation.
