The eighth title in the Pigs Will Be Pigs math-concept series by Axelrod and McGinley-Nally (*Pigs at Odds*, 2000, etc.) finds the pig family taking up square dancing and passing along lessons about spatial sense and direction. Left and right, high and low, backward, counting, sidestep, up, hop, center, back-to-back, sets, circles, pairs, and squares, of course, are mathematical terms and concepts that are cleverly woven into the story. Mr. Pig has to take over as the square-dance caller, making up his own calls as he goes along, while his family joins the dancers, pairs of animals from both farm and forest. The brightly clad dancers get tangled up from his inexperienced directions, ending up in a “pig pile” that literally brings down the house. The story serves more as an introduction to square dancing than as actual mathematical instruction, but there is an ongoing demand for elementary-grade titles that show math concepts in real life. McGinley-Nally’s vibrant illustrations in ink, watercolor, and acrylics make the most of the square dancers’ wildly patterned costumes and colorful cowboy boots. A list of square-dancing terms and an author’s note provide additional information. *(Picture book. 4-8)*
