Decimal Operations Using Base-10 Blocks This kit contains: • 10 bags of “Base 10 Cube Blue” (set of 1) • 10 bags of “Base 10 Flats Blue” (set of 10) • 10 bags of “Base 10 Rods Blue” (set of 50) • 10 bags of “Base 10 Units Blue” (set of 100) • 1 bag of “Overhead Base 10 Blocks Blue” (set of 50) • 1 activity binder Video demonstrations of the following lessons can be found at: http://tidewaterteam.wm.edu/VideoManipulatives/index.php Overview of Lesson 1 Getting to Know Base-10 Blocks In this lesson, students will explore the relationships between decimals using Base-10 Blocks. Often, students need time to explore and “play” with the new manipulative before they are ready to be guided through computations using the manipulative. Allow students time to explore relationships between the Base-10 Blocks. In order to promote higher-level thinking and to develop number sense, have students work with establishing new values based on different pieces being considered the unit. After students have become familiar with assigning values to the blocks, students will use the blocks to show values the teacher specifies as well as name the value the teacher demonstrates with the blocks. See the video, Exploring the Relationships of Base Ten Blocks at http://tidewaterteam.wm.edu/VideoManipulatives/index.php for a demonstration of this lesson.
