BETA ULTIMATH WHITEBOARD uses a visual approach to explain Pre-Algebra, Algebra, and other primary math concepts. Using the Model Method, known internationally as the "Singapore Method," UltiMath Whiteboard employs "blocks" which can be grouped, sorted, manipulated, and annotated to represent more complex word problems. There's a bit of a learning curve in both using the online tool and learning the Model Method, but the provided tutorials had us well on our way in 10 minutes. If the Model Method is brand new to you, consider that Singapore students have been tops in 3 of the last 4 TIMSS assessments.
