If a student completes 20 long division problems incorrectly, they have just spent 30 minutes learning the wrong process. With a quality answer PDF, the student checks each problem immediately.

If you are a homeschooling parent, contact Pearson Canada or a used curriculum seller (e.g., AbeBooks, ThriftBooks) for the Math Makes Sense 4 Teacher Guide. This includes the complete answer key plus diagnostic assessments. This is the gold standard of "better." If a student completes 20 long division problems
There is a dark side to answer keys. If a student simply copies the answer from the PDF into the homework book without solving the problem, they are harming their own education. This is the "worse" scenario. This turns practice into a self-correcting feedback loop
