"A little girl channels her exuberance and excessive pogo-stick jumping into a worthy fundraising venture.Jenny is a born jumper. She vaults over fire hydrants, bounds over hedges and leaps over fences, but she isn't very careful about when her jumping might not be appropriate. Her teacher scolds, 'Jumping is for frogs,' when Jenny knocks over the caterpillar bins in the science room, and she is banished from the cafeteria after she upsets the entire hot-lunch cart. Much worse is the incessant teasing she attracts from her classmates, who croak, 'Ribbit, ribbit,' whenever they see her. 'When did my Jumping Jenny become Slumping Jenny?' asks Grandma when she sees a forlorn-looking Jenny sitting on the stoop. Discouraged but still thinking positively, Jenny begins to develop an idea that will put her jumping talent to good use as part of her class 'mitzvah project.' Friends and family pledge to Jenny's jumpathon, to be held at the school's African village fair that's been to raise money for a Ugandan school.

Acrylic-on-canvas cartoon-style paintings depict a Jewish day school, with boys wearing yarmulkes and Hebrew text on the board.Bari's story of one girl's approach to the Jewish principle of 'tikkun olam' (literally, "repair the world") will resonate as readers watch Jenny achieve her exhausting, triumphant success." --Kirkus Reviews.
