DK Workbooks: Science, First Grade

Perfect for children ages 6–7, this workbook supports the expanding science skills of first graders. Among the topics covered are animal movement, muscles, bones, the heart, teeth, fossils, speed, materials, rocks, the sun, and the moon.

Developed in consultation with leading educational experts to support curriculum learning, DK Workbooks: Science is an innovative series of home-learning science workbooks that is closely linked to school curriculum and helps make learning easy and fun.

Each title is packed with exercises and activities to strengthen what children learn in school. With clear questions and supportive illustrations to help children understand each topic, the books provide practice to reinforce learning and understanding of key concepts, such as animal life cycles, the solar system, chemistry, and anatomy. A parents' section contains answers, tips, and guidance to provide support, and a certificate of achievement will reinforce confidence in kids by rewarding their accomplishments.

Standard and Primary covers are widely available through general retailers. They often have higher print runs and can be cheaper, especially during sales.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
