Introduction
4 CD-104812 • © Carson-Dellosa
Common Core Science 4 Today is a perfect supplement to any classroom science curriculum. Students’ science skills will grow as they support their knowledge of science topics with a variety of engaging activities.
This book covers 40 weeks of daily practice. You may choose to work on the topics in the order presented or pick the topic that best reinforces your science curriculum for that week. During the course of four days, students take about 10 minutes to complete questions and activities focused on a science topic. On the f if th day, students complete a short assessment on the topic.
Various skills and concepts in math and English language arts are reinforced throughout the book through activities that align to the Common Core State Standards. Due to the nature of the Speaking and Listening standards, classroom time constraints, and the format of the book, students may be asked to record verbal responses. You may wish to have students share their answers as time allows. To view these standards, please see the Common Core State Standards Alignment Matrix on pages 5–8.
