The
bin gutter area only removes the pieces once you've pressed on the
bin button. Otherwise they are left in
the gutter area to model how much you have taken away.
Select a piece then press on the
split button to split that piece into smaller pieces.
Pressing the
connect button will connect
ones back into
tens and tens back into
hundreds.
This resource is especially useful for modelling the decomposition of number during vertical subtraction.
