Tween Primes, the MoMath book club for tweens and teens: Hannah, Divided by Adele Griffin (online)
Sunday, November 7 at 5:30 pm ET (New York)
Uncommonly smart, uncommonly strange, Hannah is determined to become a success.  In the one-room schoolhouse at Chadds Ford, Hannah Bennett is a sensation.  She is a whiz at math — so adept that she teaches the other students — but in reading, she is a flop.  Give her a piece of poetry and she can tell you how many As, how many Es, how many Rs there are in it — but she cannot read a word.  Her talent is amazing, but in this small town during the Great Depression, people think that girls will only use math for household budgeting.  All at once, everything changes for Hannah when she is invited to study math in the big city of Philadelphia.  This illiterate farm girl will undertake the adventure of a lifetime, in hopes of winning a university scholarship.  As long as she stays true to herself, there is nothing — not reading, writing, or the city of Philadelphia — that is beyond Hannah’s reach.  Registration coming soon.  Learn more at tweenprimes.momath.org.

Tween Primes, the MoMath book club for tweens and teens: Starman Jones by Robert A. Heinlein (online)
Sunday, December 12 at 5:30 pm ET (New York)
The stars were closed to Max Jones.  To get into space you either needed connections, a membership in the arcane Guild, or a whole lot more money than Max, the son of a widowed, poor mother, was ever going to have.  What Max does have going for him are his uncle’s prized astrogation manuals — books on star navigation that Max literally commits to memory word for word, equation for equation.  When Max’s mother decides to remarry a bullying oaf, Max takes to the road, only to discover that his Uncle Chet’s manuals, and Max’s near complete memorization of them, is a ticket to the stars.  But serving on a spaceship is no easy task.  Duty is everything, and a mistake can mean you and all aboard are lost forever.  Max loves every minute of his new life, and he steadily grows in the trust of his superior officers, and seems to be on course for a command track position.  But then disaster strikes, and it’s going to take every trick Max ever learned from his tough life and his uncle’s manuals to save himself and the ship from a doom beyond extinction itself.  Registration coming soon.  Learn more at tweenprimes.momath.org.
