Los ciclos de vida de los peces (Fish Life Cycles)

Many insects hatch from eggs and molt several times as they grow bigger. Others, such as butterflies, undergo a complete metamorphosis. A common science curriculum topic, insect life cycles may be confusing because of these differences. However, this book breaks down these cycles into easy-to-understand steps in both accessible language and colorful diagrams readers can turn to for review again and again. The most important vocabulary needed to talk about insect life cycles is further explained in fact boxes and an extended glossary.

This book looks at the numbers in Spanish. Main text on each page is provided only in Spanish, with simple, labeled photographs providing support. A "dictionary" spread at the end of the book features all the vocabulary words in both Spanish and English, and also includes a pronunciation guide.
