三さん度ど
三度 and 三回 both mean 'three times', but 三度 has a slightly more formal or set-occasion feel (e.g. daily meals), while 三回 is the everyday, neutral counter for occurrences.

一いっ回かい
一回 means 'once' or 'one time', while 三回 means 'three times'; both are numeral+回 counter phrases that learners can mix up when adjusting the number.
二に回かい
二回 means 'twice' or 'two times', while 三回 means 'three times'; the two are easy to confuse since they differ only in the numeral before 回.
三さん階がいN5
三階 (さんがい, third floor) and 三回 (さんかい, three times) differ only by voicing but have unrelated meanings, so listeners must catch the sound difference carefully.
散さん会かい
三回 (three times) shares the same pronunciation as 散会 but is a counter phrase for frequency, unrelated to a meeting ending.

Compound of 三 (san, 'three') and 回 (kai, counter for occurrences).
