the pupils encountered great difficulty with the fundamentAl combinations. The rest of the group had other difficulties, but it is with the group of nine that this report concerns itself. The nine pupils were sent to the "remedial room," where a special teacher devotes her time to the teaching of laggards in various subjects. Upon arriving in the "remedial room," the pupils were given the Courtis Standard Practice Exercises, Lessons 45, 46, 47, and 48, to find out more specifically what processes were causing trouble for each individual. The standard for these practice lessons in Grade IV B is to complete the card with ioo per cent accuracy in 61 minutes. The results of the tests (Table I) show that most of the group were very nearly at standard in addition; that Pupils I, 6, and 9 were nearly at standard in multiplication; that the group as a whole was weak in subtraction and division; and that individuals, such as Pupils 2 and 4, showed wide variations in scores on the different processes. The nine pupils were placed in different groups according to their needs; for example, Pupils 2, 3, 4, 5, 7, and 8 were placed in one group for drill in multiplication. After but a few days of this drill Pupil 4 arrived at the standard in rate and accuracy. He then spent his time on the other processes in which he was deficient. The daily forty-minute period was divided so that each pupil drilled from five to fifteen minutes on each of the processes in which he was weak.
