This Common Core Measurement and Data lesson compares the weight of objects. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. Various objects within the classroom can be used as demonstrations. Please review the animation on the Concept Development page. Animated text is intended to be read aloud by the teacher. Also note that this lesson does not cover any form of density. All comparisons are being made between objects with similar densities. It would be worthwhile to separately cover the idea that some things may be small but heavy (a stapler, a textbook, etc.) while others are large and light (empty boxes, Styrofoam, etc.). In addition to the lesson, there are multiple pages of independent practice and review with questions modeled after the Common Core assessment items.

This lesson is compatible with all web browsers and operating systems on any PC, Mac, or Chromebook. Answers will pop onto the page with the click of a mouse or presentation remote.
