Check out these reading suggestions from World-Herald book reviewer Carol Bicak:

There is a wonderful series of books from Sylvan Dell Publishing that mixes animal stories with science and math. The books have nice bright illustrations (some better than others), and include interesting facts, questions and tests for readers, even help for teachers who want to incorportate the books into lesson plans.

And they recommend related Web sites.

The publisher says they are for ages 4 to 8, but I would put them a little older, say 6- to 10-year-olds. In addition to the print books, the titles are E-books.

Hard back books are $16.95 and soft covers are $8.95. They are available from the publisher as well as online. Check with local bookstores for their availability.

And here are the books:

"Felina's New Home" by Loran Wlodarksi (CQ), illustrated by Lew Clayton. This is the story of a Florida panther who is losing her home in the Florida swamps and forests to encroaching humans and the things they bring with them. Just when it seems Felina won't survive, a rescue organization steps in.

"Panda's Earthquake Escape" by Phyllis J. Perry, illustrated by Susan Detwiler. Based on the 2008 killer earthquake that destroyed a lot of China's buildings including the Wolong Panda Reserve, the story follows a mom and her baby as they struggle to survive in the aftermath.

"What's the Difference? An Animal Subtraction Story" by Suzanne Slade, illustrated by Joan Waites. "Ten dancing whooping cranes lose the wetland home, five find a refuge near, How many cranes still roam?" Arithmetic and nature study are combined.

"Litte Red Bat" by Carole Gerber, illustrated by Christina Wald. Animal friends offer their advice as a little bat decides whether to stay where he is for the winter or to migrate to a warmer climate.

"Newton and Me" by Lynne Mayer, illustrated by Sherry Rogers. This story in rhyme follows a boy and his puppy, Newton, as they ponder the wonders of basic physics. (Guess who Newton is named after?)

I can't recommend these enough; they're all great. Also, check out some of the previous books in this series.
