Base-10 Block Diagram: Unit, Rod, and Flat for Math Education #150294 (License: Personal Use)

This educational diagram shows three standard base-10 manipulatives: a single unit cube (1), a linear rod of 10 connected cubes (10), and a 10×10 flat square of 100 cubes (100). Each component uses consistent color coding-yellow top, white front, red side-to reinforce spatial understanding and numerical relationships in early mathematics.

Used in K-5 math curricula to teach place value, addition, subtraction, and regrouping; commonly appears in lesson plans, digital flashcards, teacher resource sites, and interactive apps where visual modeling supports conceptual learning.
