Students practice composing and decomposing 3-digit numbers using base-ten blocks in these hands-on math sorts. They explore how hundreds, tens, and ones can be regrouped and represented in multiple ways, building a deeper understanding of place value relationships.
Includes:
- Sort 1: Represent 3-digit numbers using different combinations of base-ten blocks
- Sort 2: Match 3-digit numbers to three different Base-10 models
Comes in both a no-prep printable version and a digital drag-and-drop version on Google Slides.
These 2nd grade math sorts are part of the Compose and Decompose Numbers set (Sorts 1–2 of 9).
