Here is an example from the fabulously encyclopedic old Kitchen Table Math of the quality of different textbooks. The first two problems are from Singapore Math and Saxon, respectively. The last "problem" is from the egregious and execrable fuzzy math text Trailblazers. Compare and contrast indeed!
CompareAndContrastWith "math" instruction like that, the U.S. is sure going to remain competitive with the rest of the world.

Which two pieces did you choose to compare?
How are they alike? How are they different?
Do you see any improvement in the newest piece of work as compared to the older work? Explain.
If you could redo the older piece of work, how would you improve it?
How could you improve the newer piece of work?
Parents, don't let educationists ruin your child's opportunities in life. Fight the fuzzy math plague!
