Support the site (tip)

A tip to say thanks for K12 Summer Workbooks. Everything on the site stays free and public, and nothing is locked behind this. If our lessons and apps have helped your family, you can leave an optional tip: choose any amount from $5. It helps cover hosting and the time it takes to make new lessons and apps. As a thank-you you get a short thank-you note and a printable page of question starters (the same questions stay free on our site). Grown-ups only, please. A tip is a thank-you, not a charity donation, and is not tax-deductible. Tips are non-refundable unless charged by mistake (email us).
