Abacus - Virtual Manipulative

Classic Arithmetic & Place Value

A virtual 10-row abacus designed for modeling place value and mental math strategies.

• How to Use: Slide beads from left to right on each rod. Each row represents a place value column (ones, tens, hundreds, etc.).
• Classroom Idea: Model “carrying” in addition by showing how 10 beads on one rod equal 1 bead on the rod directly above it.
