Questions

Good to know.

Who are these lessons for?

Children in Kindergarten, Grade 1 and Grade 2 (roughly ages 5 to 8), and the parents, tutors and teachers who help them. Every video teaches one Common Core math standard, so you can pick exactly the skill your child is working on.

How long are the lessons?

Most run between 1 and 6 minutes - short enough to hold a young child's attention. A few are under a minute and the longest is about 11 minutes. All 52 lessons together come to about 3 hr 18 min.

Can we try before buying?

Yes. 6 lessons are free - two from each grade - and play right here with no sign-up.

Which devices does it work on?

Any up-to-date web browser: iPad and iPhone, Android tablets and phones, Chromebooks, Windows PCs and Macs. Just open k2mathlessons.com. You can also cast or plug a laptop into a classroom screen.

Are the lessons aligned to the Common Core?

Yes. Each lesson is built around a single Common Core State Standard for Mathematics, and the standard's code (such as K.CC.A.1) is shown with the video, so you can match lessons to schoolwork. K2 Math Lessons is an independent product and is not affiliated with or endorsed by the NGA Center or CCSSO.

Are there ads, or anything my child has to sign up for?

No ads, no tracking, no chat and no child accounts. Children just press play. Buying is done by a grown-up.

How much does it cost?

$24 per grade or $59 for all three grades (you save $13). It's a one-time payment - no subscription.

How do I pay?

Checkout is handled securely by Gumroad, the payment platform for independent creators. You can pay by card or PayPal, and Gumroad emails you the receipt. Prices are in US dollars; Gumroad adds any sales tax or VAT your country requires.

What happens after I pay?

The lessons unlock on this site straight away. You also get a license key on the receipt page and by email - enter it under My lessons on any other device.

How many devices can we use?

One purchase works on up to 5 browsers or devices - for example a family iPad, a laptop and a phone. Each purchase covers one family, or one teacher's classroom.

What if it isn't right for us?

Email us within 14 days of buying and we'll refund you in full - no questions asked.
