What parents ask us.

Kindergarten through 5th grade. If your child is ahead, the packets move into the next grade's skills. If there are gaps from earlier grades, those get filled first.

These are the years everything else in math is built on: place value, adding and subtracting, multiplying and dividing, fractions and measurement. A shaky foundation here shows up in every math class after it. It's also math a parent can explain at the kitchen table without relearning it first. And all of it can be done with a pencil and paper, with no calculator, graphing tool or software, which is what lets the whole program stay on paper.

A short printable set of problems on the key skills for your child's grade and the grade below. It takes about 20 minutes with a pencil. You take a photo when it's done, and we read it within a few minutes. If everything is solid, we send one short follow-up set from the next grade up, to see how far ahead your child is. If something isn't solid yet, there's no extra set: the first packets start right there and move up or down from what your child shows. Then you get a page showing what's solid, what isn't, and what their first week would hold.

You choose the level of support. Light support is about 10 minutes a week. Standard support is one packet of about 25 minutes. Max support is two packets of about 25 minutes each. Every packet is split into short sittings.

No. Your child only ever sees paper. You use your phone to download the packet and to take a photo of the finished pages.

A printer, a pencil and a phone with a camera.

Print the packet, read the short how-to box with your child when there's a new skill, and take a photo of the pages when they're done. An answer key comes with every packet if you want to check as you go.

Typically 10 to 20 minutes a week of your time with Standard support. Print the pages, start each short sitting (and time the two-minute facts page), snap photos when they're done, and glance at what we read. Light support takes less; Max support takes a little more. Checking answers with the key is recommended but not required: we grade from the photos, and your count is a second check. That's less time than one drive to a math center, and maybe less than it takes to get your kid into the car.

You take a photo of each finished page. Our system reads every answer, compares it with the key, and looks for the mistake behind wrong answers. You see what it read and confirm it before anything is recorded.

Your child's name is in them already. You can add family, friends and pets, and what your child is into, like soccer, dance or dinosaurs. The math stays exact; the story changes.

If a skill isn't coming together after a few tries, the next packet checks the skills underneath it first, then works on the mistake your child keeps making.

Yes. From your family page you can pick any skill, and the next packet will include a quick check on it.

It's built on the Common Core math standards for kindergarten through 5th grade, covering the skills that can be practiced on paper.

Yes. Carry the One Math is nonsectarian: the curriculum has no religious content, so public charter schools and state education accounts can pay for it.

The check-up is free, and so is the first month of weekly packets: it starts the day the check-up is done, and no card is needed. After that, $20 a month for your first child and $15 a month for each of up to three brothers or sisters. A fifth child or more is $20 each. Or pay yearly: $200 a year for the first child and $150 for each brother or sister. That's the school-year price, with summer included. Cancel any time. If you do, we keep your child's history for 30 days in case you come back. After that, it's deleted, and starting again means a new check-up. The check-up is free.

Yes. A year for one child is $200, paid once on the gift page. You get a membership code and a printable certificate by email, and we can email it to the family for you, right away or on a day you choose. The family starts with the free check-up and enters the code on their family page; the twelve months begin then, with no card needed.

Yes, in many states. Carry the One Math is a K–5 math curriculum, the kind of purchase these programs cover. See paying with an education account for how it works and where we're listed.

Yes. Once your membership starts, your family page has a link to share. When a family signs up with it and pays their first month, you both get a month free, taken off your next bill.

Summer is a great time to keep going. A few short sittings a week keep skills from slipping, and reviews bring back what was learned during the school year. Staying enrolled also keeps your child's skills map and plan: if you cancel, their history is deleted after 30 days.
