Hundreds, tens and units

This is an interactive resource that represents numbers visually as groups of hundreds, tens and units. It can be used to count numbers by partitioning them based on place value, or to represent numbers by building them from grids of hundreds, tens and units. The numerals matching the visual representations can be visible ...
