Tens and ones can also be represented as 'T' and 'O'
        on the rods.


        For example, 13 has 1 ten and 3 ones. See how it is
        shown on an abacus.                                                                     T      O

                                                                                                1       3





              Count and write the number of beads on each rod of the abacus.














                 T       O               T       O               T       O                T      O







              Draw beads on the abacus to show these numbers.
