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.

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.

What’s the difference between the daily email and the Bedtime Math app?

Our mobile app features the same set-up story and questions as the daily email. If you’re already dealing with too much email, you might prefer the app! Check it out by clicking on the purple box reading “Our Wacky Math App” in the upper right corner of any page of this site.

I love Bedtime Math, but I speak Spanish. Do you provide the daily math problems in English as well as Spanish?

Yes, we do! The Bedtime Math app is now available in English and Spanish for iPhone/iPad and Android. Our book, Bedtime Math: A Fun Excuse to Stay Up Late, is also available in Spanish.

What do the question labels like “Wee ones” and “Little kids” mean? What level of math are they?

We avoid using age or grade levels so that kids feel comfortable tackling as many or as few of the questions as they like. The questions start with Pre-K math such as counting and shapes and get more challenging from there!

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

We gladly take suggestions all the time! Anyone can become a Superfan by sending a specific topic or question to with your kid’s first name and last initial. If we use the topic, we’ll be sure to give your kid a shout out, and include you on our Superfan website page.

We love the Bedtime Math books. Where can we buy the books?

Everything Else

I’m a teacher and want to do Bedtime Math in school or as homework – is that okay?

No – it’s not okay! Bedtime Math’s mission is to help kids love math as much as playtime or dessert, not as part of their studies. All of our offerings are purely recreational and meant for kids to do with their friends or families after school so it doesn’t feel compulsory or like school work. Getting families to embrace math as a fun activity is the core of our foundation’s mission. And best of all, it’s proven to boost kids’ math skills. Here’s a quick, informative flyer you can email or print out for your students’ parents: [in English] [en español].

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?

Since 2014, the Collaborative Summer Library Program (CSLP) has exclusively offered 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.
