Multifaceted Number Concepts 183Successful Strategies
To help strengthen understanding of the expanded form
concept students need to build numbers with place value
manipulatives (such as base ten blocks and Digi-Blocks TM ).
As students build numbers, they need to discuss what the
values look like and the differences among values within the
number. The math discourse combined with the visualization
and manipulation is powerful for students.
