A flexible, multi-purpose Base 10 Volume set which allows pupils to see, touch and learn the relationships between volume, area and mass. The set includes 3 subsets in red, blue and purple (each subset comprises a 10cm cube, 10 hundreds, 50 tens and 100 ones). Also supplied is a shatter-proof transparent cube which holds 1 volumetric litre and comes packed with 9 flats, 9 longs and 10 units all in purple. This resource addresses the raised curriculum demand to secure 100s in year 1 as part of the move to columnar calculation.
