Seeing Symmetry

Loreen Leedy’s nonfiction titles are classroom staples.  Seeing Symmetry is a stimulating concept book, a picture book that explores many aspects of the mathematical concept of symmetry.  In addition to tackling line symmetry, Leedy also explores rotational symmetry and explains asymmetry.  Although the pages are a bit crowded, the images clearly support the text and have great "kid appeal".

The choice of images reflects diversity and young readers’ interests.  For example, the double-page spread focusing on symmetry in art includes a Mexican paper-cut banner,
an African mask, Pennsylvania German fraktur painting, Mimbres pottery, medieval stained glass, Chinese lattice work, a Haida totem pole, a Japanese ternari ball, and a Turkish kilim rug.  Iconic images of the Taj Mahal, Hilton Head Island lighthouse, and the Lincoln Monument are used to point out the symmetry found in architecture.  Other images range from sea turtles to ballerinas. 

Grace Wilkie, a mathematics expert with impressive credentials (including
being a past president of the Association of Mathematics Teachers of New York State and New York State Mathematics Honor Society), reviewed this book for accuracy.  The book meets the Common Core State Standards for fourth-grade mathematics (although the notice printed in the book contains errors: "This books meets the Common Core..."), and a typo ("their" instead of "there") that occurs on page 7.

Leedy, Loreen The Shocking Truth about Energy

“ An illustrated introduction to energy, covering the forms it can take, such as heat, light, fuel, and electricity, and examines topics such as global warming; nuclear, solar, and wind power; how energy transfers from the sun to food to people's muscles; and how to sensibly conserve energy around the home.” Elementary students will enjoy this new graphic title on energy. Energy is something we use everyday, but we just don’t think about all the ways it affects us. Students are introduced to Erg, and he’s pure energy. Erg helps us understand the many different forms of energy. Erg tells us while everybody loves energy for everyday things, its hard to catch it because it can be heat, light, sound, fuel, motion, or electricity. When we eat food, its our fuel for our muscles and becomes muscle power. In a highly graphical manner, students are introduced to the power of fossil fuels and how they are burned to make electricity. When fossil fuels burn, they release carbon dioxide, a greenhouse gas, and then we have issues of global warming. Nuclear power is introduced and it uses the energy of atoms. Solar power is another form of energy and its free, clean, and renewable. Another form of energy is wind power and through wind motion it creates electricity. When the wind is not blowing, no power can be made. Water power helps create energy too through the motion of rivers and oceans. Geothermal power uses ground heat pumps to produce energy. Plant power use the energy from sunlight to make things for fuel. The author provides many money saving energy tips for kids and grown-ups.

Includes additional information about energy, along with recommended web sites and more bad news about fossil fuels. Students will love the graphical format. Reluctant readers will also do well with this title. Would make a great addition to an elementary school collection. Forba-Mayer,Charleen
