I find both skills very necessary.
My dc are in situations all the time that require both of those skills (have no idea who the kids are that fall in the category of the ones that will not need it…do they have credit/debit cards, iphones??!!). I found out the hard way when my dc were in music class and were given “play money” to buy prizes at the end of the year and my 7yo had not quite mastered the skill (or acted like he hadn’t) of counting money and the teacher was kind of surprised that he hadn’t learned it yet. I was a bit embarrassed, even though I plan to teach it, complete with counting back change, as well. And, telling time is akin to math (skip counting, rounding, fractions) and a lot of our older friends have analog clocks (grandfather clocks) and we prefer them over digital for decorative purposes. Also, our dc receive cash for their birthdays/Christmas are required to put it in the bank, but, they have to count it out and work with the bank teller themselves.
What a bunch of idiots. I know that wasn’t very nice, but come on!
