 | | The Slavonic abacus can be used to develop helpful images of number, partitioning, addition, complementation, and multiplication. |
 | | The Slavonic abacus, see Figure 2, described by Grauberg in her book Elementary Mathematics and Language Difficulties, provides an invaluable tool to enable pupils to 'see' numbers and number bonds to ten, and then to a hundred. |
 | | Rather, they should be helped to identify the sixtieth bead, and then the eighth bead in the next row, by looking at the pattern of beads on the abacus, and recognising that 'sixty' is 'five plus one' rows, and 'eight' is 'five plus three' beads. |
