Based on Next Generation Science Standards and Singapore methodologies, Primary Science 2A builds on the concepts of matter and systems, taking a deeper look at Earth’s systems and changes, as well as the properties of matter. Through age-appropriate language, visuals, and activities, Primary Science helps students build a deep understanding of subject matter, strengthening critical thinking, collaboration, and communication along the way. Topics are divided into two semesters: A and B. Each Worktext includes “how to use” information, student readings and activities, and consumable worksheets. Purchase of the Student Worktext includes a digital access code to digital student and instructor material. This series is designed without printed Teacher’s Guides, with all instructor resources thoughtfully provided in a convenient digital format.
