Kumon Level O Solution Book

Every Kumon student receives an (final answers only) for self-checking. Do not flip to it until you have worked the problem twice. If your answer differs, do not erase. Circle the discrepancy and attempt to reverse-engineer where you diverged. This "error analysis" is more valuable than a solution book.

It provides the full logical progression for each problem, not just the final answer. kumon level o solution book
