Small Number Cards Box

The Small Number Cards Box stores the small number cards sorted by hierarchy, so units, tens, hundreds and thousands each keep a place of their own. Taken out, the cards are laid one over another until the zeros disappear and a four digit number can be read as a single figure, then pulled apart again to show what it was built from. A child fetches only the cards a piece of work needs and returns them without sorting the whole set again, which is what keeps decimal material usable day after day. A storage piece for the mathematics shelf from three years, beside the golden bead material the cards are used with.
