Frequently Asked Questions (FAQs)

Some questions we are often asked… and their answers:

The Daily Math Problem

How do I sign up for the daily email?

It’s easy! At the bottom of any page on this website, you’ll see the words “Sign me up” in the lower right-hand corner. Just fill out the form, click the “Sign Up” button, and you’ll start getting the daily email. If you’re having trouble with this, you can also email us at to let us know you want to receive the daily math problem in your inbox and we’ll sign you up manually.

Can I get the daily math problem on my phone or tablet?

Yes, you can! We have an app for Apple devices and one for Android devices. Both apps are universal (you can use them on a phone or tablet) and both are entirely free!

I get the daily email. Now what?

Have some math fun with the little ones in your life! Read the set-up story and do any or all the levels of the math problem. The answers for each level are included below all the questions, to make things a little easier for everyone. Have fun discussing any topics that the Bedtime Math problem may bring up. If your kids are stuck, you can walk them through the steps to help them get the answer.

I was receiving the daily math problems and then they stopped all of a sudden. Why did this happen and how can I fix it?

We often find that people forward the email to a friend, and their friend accidentally unsubscribes them. If you’re suddenly not receiving the daily math problem, email us at and we’ll work with our email marketing company to get the email sent to you.

We’ve graduated from the daily email. How do I unsubscribe?

At the bottom of each daily email, there’s a “SafeUnsubscribe” link that you can click and be unsubscribed.

My child has an idea for a Bedtime Math problem topic. Do you take suggestions?

We love hearing ideas for math problems from our fans! You can email your idea to with your first name and first initial of your last name. If we use your topic, we’ll be sure to give you a shout out!

Everything Else

I’m a teacher and would love to spread the word about the Bedtime Math movement to my students’ families. Do you have any promotional materials you can send me?

Yes, we do! Here’s a quick, informative flyer you can email or print out for your students’ parents. Your school may also be interested in hosting a Crazy 8s club as part of its after-school programming.

I’m a public librarian and I want to incorporate Bedtime Math’s Summer of Numbers into our summer reading program. How do I order calendars and star stickers?

We’re partnering with the Collaborative Summer Library Program (CSLP) who is exclusively offering Summer of Numbers as a companion to their summer reading program. Participating libraries can order their materials at Bedtime Math will also continue to offer a free monthly calendar on our website, which you can print on your own.

What is Bedtime Math’s business model?

Bedtime Math is a nonprofit operating foundation, funded by charitable donations made by private donors. The foundation’s resources are used to advance the mission of helping kids learn to love math. All proceeds from the sale of both Bedtime Math books are used to help offset the cost of producing and distributing Crazy 8s and other Bedtime Math programs.

I see that Bedtime Math is a foundation. Do you offer grants?

Bedtime Math does not make grants to other nonprofit organizations or to individuals. As a private operating foundation, Bedtime Math funds its own charitable activities, such as publishing the daily math problem and the parents’ blog, and producing programs like Crazy 8s and Summer of Numbers.
