This scaffold is based on the principle that cyclic patterns form in the final digits of numbers in the times tables. When this pattern is reversed, it forms another cycle corresponding to a different times table. For example, look at the 3 times table: (0), 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 . The final digits 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 will keep repeating on and on for ever (the same will be true for the 13, 23, 33 and so on... times tables).If we reverse the order of the pattern for th
