Danica Mae McKellar (born January 3, 1975)^[1] is an American actress, mathematics writer, and education advocate. She is best known for playing Winnie Cooper in the television series The Wonder Years.

McKellar has appeared in various television films for the Hallmark Channel. She has also done voice acting, including Frieda Goren in Static Shock, Miss Martian in Young Justice, and Killer Frost in DC Super Hero Girls. In 2015, McKellar joined part of the main cast in the Netflix original series Project Mc².

In addition to her acting work, McKellar later wrote seven non-fiction books, all dealing with mathematics: Math Doesn't Suck, Kiss My Math, Hot X: Algebra Exposed, Girls Get Curves: Geometry Takes Shape, which encourage middle-school and high-school girls to have confidence and succeed in mathematics, Goodnight, Numbers, and Do Not Open This Math Book.^[2][3][4]

McKellar was born in La Jolla, California.^[5] She moved with her family to Los Angeles when she was eight. Her mother Mahaila McKellar (née Tello) was a homemaker; her father Christopher McKellar is a real estate developer; her younger sister Crystal (b. 1976) is a lawyer.^[6] She is of Scottish, French, German, Spanish, and Dutch descent on her father’s side, and of Portuguese origin, via the Azores and Madeira islands, on her mother’s side.^[7]

McKellar studied at the University of California, Los Angeles where she was a member of the Alpha Delta Pi sorority^[8] and earned a Bachelor of Science degree summa cum laude in Mathematics in 1998.^[9] As an undergraduate, she coauthored a scientific paper with Professor Lincoln Chayes and fellow student Brandy Winn titled "Percolation and Gibbs states multiplicity for ferromagnetic Ashkin–Teller models on ${\displaystyle \mathbb {Z} ^{2}}$."^[10] Their results are termed the "Chayes–McKellar–Winn theorem".^[11][12] Later, when Chayes was asked to comment about the mathematical abilities of his student coauthors, he was quoted in The New York Times, "I thought that the two were really, really first-rate."^[13] For her past collaborative work on research papers, McKellar is currently assigned the Erdős number four, and her Erdős–Bacon number is six.^[14]

At age seven, McKellar enrolled in weekend acting classes for children at the Lee Strasberg Institute in Los Angeles.^[15] In her teens, she landed a prominent role in The Wonder Years, an American television comedy-drama that ran for six seasons on ABC, from 1988 to 1993. She played Gwendolyn "Winnie" Cooper, the main love interest of Kevin Arnold (played by Fred Savage) on the show. Her first kiss was with Fred Savage in an episode of The Wonder Years.^[16][17] She later said, "My first kiss was a pretty nerve-wracking experience! But we never kissed off screen, and pretty quickly our feelings turned into brother/sister, and stayed that way."^[18]

Her first book, Math Doesn't Suck: How to Survive Middle School Math without Losing Your Mind or Breaking a Nail, was a New York Times bestseller,^[2] and was favorably reviewed by Tara C. Smith, the founder of Iowa Citizens for Science and a professor of epidemiology at the University of Iowa.^[28] The book also received a review from Anthony Jones, writing for the School Librarian journal, who described the book as "a trouble-shooting guide to help girls overcome their biggest maths challenges," noting what he described as "real-world examples of great mathematics in action."^[29] In an interview with Smith, McKellar said that she wrote the book "to show girls that math is accessible and relevant, and even a little glamorous" and to counteract "damaging social messages telling young girls that math and science aren't for them".^[30]

McKellar's second book, Kiss My Math: Showing Pre-Algebra Who's Boss,^[31] was released on August 5, 2008. The book's target audience is girls in the 7th through 9th grades. Her third book, Hot X: Algebra Exposed!^[32] covers algebra topics, while the previous two titles were intended as "algebra-readiness books."^[33] Hot X was published on August 3, 2010. Her fourth book, Girls Get Curves – Geometry Takes Shape,^[34] focuses on the subject of geometry, and attempts to make the subject more accessible.^[35]

Three of McKellar's books were listed in The New York Times children's bestseller list.^[36][37] She received Mathical Honors for Goodnight, Numbers.^[38]

McKellar was named Person of the Week on World News with Charles Gibson for the week ending August 10, 2007. The news segment highlighted her book Math Doesn't Suck and her efforts to help girls develop an interest in mathematics, especially during the middle school years.^[39] In January 2014, she received the Joint Policy Board for Mathematics (JPBM) Communications Award. The citation credited her books, blog, and public appearances for encouraging "countless middle and high school students, especially girls, to be more interested in mathematics."^[40]

McKellar married composer Mike Verta on March 22, 2009, in La Jolla, California; the couple had dated since 2001.^[41] They had their first child, a son, in 2010.^[42][43] McKellar filed for divorce from Verta in June 2012.^[44]
