From the Smithsonian, an ingenious introduction to shapes and seashells. A series of questions-and-answers lead toddlers through a gallery of shells: “What is fan-shaped with stripes and ridges? A scallop shell!” appears next to a dramatic photograph of said shell on the sand. Some images respond better than others to the concept, but all in all, it’s a lovely way to engage older toddlers in some value-added beachcombing. Publishes simultaneously with My Beach Book (ISBN: 978-0-06-111574-5).
