哪个是新加坡数学正版？

1。Math Practice (Singapore Math) , Frank Schaffer Publications 2009

http://www.amazon.com/Practice-Singapore-Frank-Schaffer-Publications/dp/0768240018/ref=pd_sim_b_14

还有其他补充练习吗？好像题目不够多。

2。Primary Mathematics Intensive Practice , SIngaporeMath (Author) 2004

http://www.amazon.com/Primary-Mathematics-Intensive-Practice-SIngaporeMath/dp/1932906029/ref=sr_1_1?s=books&ie=UTF8&qid=1301526641&sr=1-1

好像是旧版，对吗？
