Cover of picture book biography Numbers in Motion shows Sophie Kowalevski looking at numbers and equations as she spins a child's top

Numbers in Motion tells the inspiring story of Sophie Kowalevski. Kowalevski was a nineteenth century mathematician. She managed to study advanced mathematics. Find a post as a mathematics professor. And solve some of the most intractable problems facing math at the time.

In this book, Laurie Wallmark introduces us to Sophie as a child. The text describes in simple, easy-to-understand terms her landmark mathematics discoveries. It also celebrates her remarkable achievements in a society that kept trying to steer her away from math.

The art, by Yevgenia Nayberg, is evocative and lovely. I was especially taken by the book design. Various spreads use empty space very effectively throughout. And the text is in a wonderful typeface that’s clean and self-effacing, sending the reader’s attention right back to the lucid prose.

Laurie talks about the book in this video link, from a book event the two of us did together (available through 29 May 2020).

Sweet Dreams Sarah by Vivian Kirkfield is a nonfiction picture book that hits the sweet spot of combining STEM principles with social studies content.

In the book, we see the engineering process at work. Every element of the story zeroes in on the engineering process:

identify the problem

brainstorm solutions

construct a prototype

analyze the results

redesign

A nineteenth century, newly-freed woman, Sarah, tries to solve a problem for the customers in her furniture shop. They live in tiny apartments and the furniture she sells is just too bulky. Once she has identified the problem, she brainstorms solutions and builds a prototype. The prototype has problems so she redesigns it. When her patent is rejected, she revises and resubmits it. Her story would be a great introduction to a unit on invention

At the same time, her story has lots of social studies content that can spark conversation and build understanding in kids. It addresses slavery, Reconstruction, entrepreneurship, and how government processes (like patents) work. Importantly, it discusses the roles of women in history in a clear way.

The book is clear and fun to read aloud. It keeps the story active and moving along with refrains like, “Measure. Cut. Sand.”

And now I want one of the desk-beds that Sarah invented!

Cover of book shows young Jane Austen writingOrdinary, Extraordinary Jane Austen surprised me. Why would an elementary student be interested in Jane Austen? But Deborah Hopkinson convinced me with her sweet biography that focuses on how very ordinary Jane was, and yet able to develop her talent in an extraordinary way by observing, reading, and writing, writing, writing. It’s a heartening story for those of us who also feel ordinary.

The back matter includes a short summary of each of Austen’s novels (a good idea since I don’t think many children have read her yet!) and famous quotes from each book, as well as places to learn more about Jane Austen. The illustrations are charming and accessible, and the endpapers are the sweetes pink of the year.

Cover of book shows Belva Lockwood protesting in front of CapitolA Lady Has the Floor tells the inspiring story of Belva Lockwood, who started out as an educator who reformed the schools she worked in so that girls got to have the same experiences as boys–public speaking, physical activities. She then broke down gender barriers to attend law school, and was the first woman to argue before the Supreme Court. As if that weren’t enough barrier breaking, she next became the first woman to run for president, even before women had the right to vote. She said, “I cannot vote, but I can be voted for.”

The back matter for this book about a trailblazer includes a detailed timeline that includes events that happened after her death but are arguably her legacy. I loved that it included source notes for all the quotations in the book. The art was made with a crackle varnish that gives all the pictures an old-timey feeling.

Cover shows young Lil Hardin Armstrong playing pianoI wasn’t sure who Lil Hardin Armstrong was when I read the subtitle of Born to Swing. Louis Armstrong’s daughter? His sister? I was surprised to learn that she was his wife, and much more famous than him at first. The back matter includes a telling quote from a 1925 newspaper: “Louis Armstrong. Who is he?…Louis is the feature man in Lil’s jazz band at the Dreamland.” This lively biography tells the story of how Lil moved from the church music that her mother approved of to the jazz that she adored. The book is written in first person. Mara Rockliff explains why she chose first person:

Since Lil never got to tell her own story, I tried to tell it as she might have chosen to. I used many of her own words from the interviews she gave over the years. Like all stories told aloud, lil’s stories changed a little every time she told them. Sometimes she even bent the truth a bit. Reading what other people said about her helped me bend it back.
