Frequently Asked Questions
What do I get with a membership?
Full access to the complete PreK–5 program: 135 lessons per grade level, unlimited worksheets and spiral review, diagnostics and assessments, the full Digi-Tools suite and virtual manipulatives, instructional videos, games and tournaments, plus recorded teacher PD and student lessons.
How does pricing work for more than one child?
One child is $24.99 a month ($249.99 a year). The Family plan covers up to 3 children for $29.99 a month ($299.99 a year). Your own parent account is always included. You can switch plans at any time from Manage billing, in your family home or your profile menu. An upgrade is charged the difference right away, and a downgrade becomes a credit toward your next payments. More than 3 children? Email contact@tangmath.com and we'll look at adding a student or two to your plan, or see our annual Classroom plan for up to 10 students.
How does the free trial work?
All plans start with a 7-day free trial, once per family. We take your card at checkout but charge nothing until the trial ends. Cancel anytime before then from Manage billing, in your family home or your profile menu, and you won't be charged. We also email you a reminder 3 days before it ends. Your first payment is still covered by our 30-day money-back guarantee.
Should I choose monthly or annual?
Both plans include exactly the same access. Monthly is the most flexible; annual costs less over a full school year. You can switch between them later from Manage billing, in your family home or your profile menu.
Can I cancel?
Yes — anytime, with no cancellation fee. Cancelling stops future renewals, and you keep full access through the end of the period you already paid for. New memberships come with a 30-day money-back guarantee; see our Billing & Refund Policy.
Do I need an account first?
No. Enter your email above and we'll set up your account as part of checkout. If you already have a Tang Math account, please log in first so your membership is added to it.
What about school or district pricing?
Schools and district orders include accounts for all staff, custom quarterly PD, and volume pricing. Email contact@tangmath.com and we'll put together a quote.
