Thanks, a separate sentence is an excellent idea, but we will need reliable sources for it. Rather, than tag bomb the sentence, I'll do it here:
""typically in education""
""everybody knows"" (students are included in ""everybody"", but they don't know ""the other kind of numbers"")
""natural numbers  counting numbers"" (natural numbers with or without zero?)
Why was the term ""counting numbers"" introduced ""circa 1965""? (per Merriam-webster.com)
At what educational level is the term ""counting numbers"" replaced with another term?
Sourcing ideas include books on pre-algebra and mathematics curriculum standards.
