Still in my head are counting rhymes that I learned in childhood -- an early connection between mathematics and poetry that I think helped me to love both subjects. Here is a link to a list of more than forty math-rhymes -- and including one that is also in Spanish.
This rhyme is one that has been useful to me throughout both childhood and adulthood-- as I strive to remember which months have thirty days.
Thirty days hath September,
April, June, and November;
All the rest have thirty-one,
Excepting February alone,
Which has twenty-eight in line,
Till leap-year gives it twenty-nine.
AND, today's issue of the Washington Post has a cartoon by Tom Toles -- about recounting votes after last week's election -- that also involves a counting rhyme: I offer part of the rhyme below but the visual is critical -- and available here.
One, two, none for you.
Three, four, they fell on the floor.
Five, six, it takes some tricks . . .
Seven, eight, to make America great.
