This post provides access to and details about a Google Jamboard with scaffolded background to support multi-digit subtraction with regrouping.

The Jamboard has images of basic base 10 blocks. The background provides side by side tables for numbers and for blocks. Additional blocks are set aside for regrouping. Here is a FB Reel and a YouTube video showing how to use this artifact.
