There is a learning difference known as dyscalculia, thought to be present in 3–6% of the general population. It's sort of the math version of dyslexia.
Someone with dyscalculia can have a genius IQ.
Yes, this does exist. There are many more examples of high IQ people with learning issues, but who have excellent numeration than those with poor numeration. However having dyscalculia doesn't indicate poor intelligence.
Measured intelligence in general is a vastly overrated metric. Common sense is in many ways more important, as demonstrated by the posting of the people in this very thread.
TBH, kids these days are required to do a lot less independently because the world has evolved into a place where thinking is unnecessary. Kids don't count coins in piggy banks anymore. They don't need to read clocks. They don't need to keep track of schedules for cartoons. Less natural number development. Thus, teachers need to be able to do more in the classroom to address this and in America many teachers are simply underqualified to do so.
