About googoodan.com

googoodan.com provides elementary math explanations, printable practice and answer keys for families and classrooms. The English library covers selected kindergarten through Grade 5 skills. It is not a complete curriculum or an official textbook supplement.

How the materials are made

Worksheets use our existing question banks and generation tools. English materials adapt the language, number ranges and skill placement for the English library. Each lesson includes examples to read before generating a practice set. References to Common Core describe selected skill connections, not official endorsement.

Choosing suitable practice

Start with the worked example and check the number range. A grade label is a guide; children may need earlier skills or a smaller practice set. An adult can check the answer key and help explain mistakes.

Corrections

If a question, explanation or answer seems wrong, please send a correction report. Include the page and set link so the same question can be checked. We do not claim that every possible generated set has been independently reviewed.
