How do you access an exSTEMsions Problem?

Each week, we post our new problem-solving journey at midnight on Sunday. You’re welcome to get started as soon as it posts! You can do this by logging into your account at  - you’ll automatically be brought to the newest Problem. On Monday, you’ll get an email reminder that the new Problem has appeared, with a link that you can use to log in right from the email.

Once the Problem posts, how does my family work on it?

When you log in, you’ll be brought to the latest Problem.  (If you happen to be elsewhere in your account, head over to This Week in your Dashboard for access.)   Begin the Problem by carefully reading it! Once you and your child have read through the Problem a few times, make sure your child really understands what they are being asked to explore. From there, all your child needs is a brain, some paper, and a pencil… start solving! Some problems come with materials to download - feel free to print those out and use them as you work.

As our problem experiences are web-based, this makes it easy to work from wherever you and your child are, whether you’re accessing our site from a computer, a tablet, or your phone.  

And we don’t ask you to type any answers into the site, because our problem-stories don’t have answers, they have Solutions.  The Solutions are there for you to dip into wherever you feel like, whenever you’re ready, to inform your understanding, or just to check it.  This is not meant to be a torturous experience, but a relaxed adventure!

The Problem, along with its Exstemsion problem, both Solutions, and all the supporting tools are there for you, however you choose to use them, every week.

Why should I pay for exSTEMsions when I can sign up with another company for a problem-of-the-week for free?

exSTEMsions is WAY more than a problem a week. Each week, we post a new, expert-teacher crafted journey for you and your child, that will help develop and strengthen vital math, critical thinking, and problem-solving skills. Each Problem truly is a unique and original journey through amazing mathematics - you won’t find anything like this anywhere else.

Every successful journey requires at least a few tools, and our problem-solving journeys are no exception.  We want to provide you with a complete, enriching experience every week. And that takes a bit of doing!

Each Problem comes with an additional Exstemsion problem, that extends or riffs on the ideas of the Problem; each problem comes with a user-friendly Solution.  The Math Category lets you know the kind of math you’ll be thinking about, and the Thinking Skills clue you in on how you’ll be thinking about it.  Our Supporting Questions give you the language to help your child when s/he most needs it.  And when you’re finished both problems, you’ll check out the Big Ideas that will wrap up the whole experience in a nice little package.  All this, every week!

Click here (and scroll down to “Our Tools”) to get a brief overview of all the pieces to each Problem experience, and click here to read about everything in a little more detail.

What if we finish a Problem before the end of the week?  Is there anything else we can work on?

Definitely! Depending on the plan you choose when you join exSTEMsions, you will have access to our complete problem Archive, providing your family with access to many more problem-solving adventures!

And with the archive, you can choose your own adventure!  Feel like sticking to geometry problems? You can do that.  Interested in probability and statistics? Then stick to those for a little while.  And then there are the many problems that just can’t be classified so easily. They’re all really fun and different… you’ll want to experience every one!

Will I, as a parent who is not a math teacher, really be able to do this with my child?

YES! You don’t have to love math, or be a math expert or teacher, to use exSTEMsions successfully.  We wrote it for inquisitive parents and children. We wrote it for families who are open to new and fun challenges, and all the excitement that kind of learning can bring.  

We didn’t write this for experts!  We wrote it for people who maybe are a little afraid of math, but definitely aren’t afraid to become the experts!  And you will!

And if you get really stuck? We’re here to help - reach out to members of our community through our private Facebook group, or directly to the exSTEMsions team. You can do this, and we’ve got your back if you need us!

Why should I trust exSTEMsions to give me awesome and unique mathematics?

exSTEMsions was created by content experts who honed their craft through teaching! Together, Sara and Elizabeth have more than 35 years of experience in mathematics and math education.  Our CEO has a Master’s Degree in math and science education. Our Chief Content Officer has two Masters’ Degrees: one in mathematics, and another in math education. They are also both parents, who understand the value of instilling a love of math, and strong critical thinking and problem-solving skills, in their own children.  For more details on who we are, click here.

The goal of exSTEMsions flows quite naturally from the experiences and beliefs of the people behind it: to enable parents, the people who know their children best, to help their children develop the vital skills that will serve them well in school now, and in their future lives and careers as well.

Honestly… I’m still not sure it’s right for my family….
