Kid Speak Definition
Cardinal numbers are numbers that we use to count objects. They are different from ordinal numbers that go 1st, 2nd, 3rd, etc. Sometimes people get cardinal and ordinal mixed up. It might help to think of the ordinal numbers showing order and the cardinal numbers showing “how many” of something.
