STC Literacy Series™: Comparing and Measuring

0.00 - 0.00

Grades K–2. Did you know that healthy fingernails grow more than 1” per year? Or that the largest volcano on Mars, Olympus Mons, is about the same size as the state of Arizona? Comparing and Measuring, part of the STC Literacy Series™, brings physical science to life with interesting facts and concepts like these. The book relates real-world situations to the skills of comparing, matching, and measuring, helping students learn how to make sense of their lives and conduct experiments.


In this book, children explore the developmental sequence of comparing, matching, and measuring.

Grades K–2. Students read about how to compare different animals and objects found in our world, and what units of measure and measuring tools we can use to find height, width, and distance.

Developed to enhance the teaching of the Science and Technology Concepts™ (STC™) unit, the STC Literacy Series™ Comparing and Measuring reader supports inquiry-based science lessons with engaging informational text. The content gives students a natural transition from hands-on investigations, builds background knowledge to reinforce conceptual learning, and lets students apply relevant nonfiction to their own real-world experiences. Questions provided throughout the book encourage critical thinking and allow children to be actively involved in their learning.

Educational studies show that children are more likely to engage in a reading exercise when the literature is related to a recent hands-on activity. This is exactly how the STC Program™ works. Included in every STC-Elementary™ kit, the STC Literacy Series™ helps improve reading comprehension, and supports the following Common Core Standards:

  • RI.1-3
  • RI.4-6
  • RI.7-9

Comparing and Measuring paper version (item #971396) comes as a pack of 8 readers. Comparing and Measuring electronic version (item #971396E32) allows 32 students per year to have access to the text for 60 months.
