Base-10 Blocks Visual Guide: Units, Rods, and Flats for Math Education #1708557 (License: Personal Use)

This diagram shows three standard base-10 manipulatives: a single unit cube (1), a linear rod of ten connected cubes (10), and a square flat made of 100 cubes arranged in a 10×10 grid (100). Each piece is color-coded with yellow tops and red side faces to emphasize dimensionality and grouping. These tools are foundational in elementary math for modeling numbers, regrouping, and understanding decimal place value.

Used in K-5 math curricula, teacher resources, and online learning platforms to teach number sense, operations, and place value; ideal for visual learners and interactive digital lessons.
