|I. From a 2nd grade Investigations math homework sheet assigned 8/9 of the way into the school year:|
|II. From a multiplication assignment from the beginning of the second half of the 2nd grade Singapore Math curriculum:|
|III. Extra Credit|
1. Should the child whose answers to the first problem set are recorded above be required to redo the problem with pictures of items repeated in 8 rows, 3 columns; 6 rows, 6 columns; and 7 rows, 4 columns? (Extra credit: how many pictures in total does that amount to?)
2. What about the Singapore Math students? Are they missing out on something by never being required, anywhere in the curriculum, to draw items repeated in rows and columns in order to "represent" multiplication?
