|1. From the 4th grade Investigations Student Math Handbook, pp. 13-15, given out in January:|
2. From the 3rd grade Singapore Math Primary Mathematics 3A Textbook, about midway through the first half of 3rd grade, pp. 54-59:
3. Extra Credit:
Are the six demonstrations of a single algorithm, as seen in the Singapore Math textbook, an instance of "rote" teaching--as opposed to the single demonstrations of four different methods in the Investigations handbook?
By 5th grade, Investigations students are two years behind Singapore Math students. Is it because of "Chinese mothering," or might there be some other factor at work here?
