$x+3=5$
Each side of the diagram represents one side of the equation. The bar separating the two sides represents the equal sign. The left side includes a green tile. The green tile represents a variable such as x. The left side also includes 3 yellow tiles. Each yellow tile represents +1, so 3 yellow tiles is +3. The right side contains 5 yellow tiles, so it represents +5. Combine the parts into an equation. $x+3=5$
