Singapore uses good multi-step problems which require students to synthesize previously mastered skills and knowledge--which is what critics of traditional math keep wanting to see. They continually ask, "Why can't students apply prior knowledge to new situations?" Probably because they are given a steady diet of challenging problems that are not knowledge/age appropriate in the hopes that they will learn what is needed to solve the problem in a "just in time" basis. This is sometimes called "embedded learning".
Investigations provides the bare minimum and students may be 2 years behind traditional math students by 5th grade. And then people wonder why kids can't apply their prior knowledge to non-routine problems. Usual reasons given: Teachers didn't teach Investigations (or EM or whatever) with fidelity. Students are inattentive and unfocused.
