"I use this in my classroom and the kids love it. We use it as an early-finisher activity. They even take them out to recess in their notebooks to practice."
"My 8 year old son loves this! I love it too — it saves my hand from writing out 100s of problems for him! (Not paid for this comment :)"
"This thing changed my weekends. When my son does something bad, now his punishment is math — unlimited math practice. I love it, I'll buy another if I lose this one!"
"Meh. It's okay. It works. I'm just underwhelmed."
"Daughter in 2nd grade is practicing add and sub skills. She loves it! Has fill-in-the-blank and multiplication too. Easy to use and has worked well so far. Recommend!"
"For a homeschool parent, this makes life a little easier. Instead of writing out or printing math facts, just roll them on, press a knob and roll away again!"
"Granddaughter attacks it every morning. Addicting for children. All good."
"No need to write down multiplication, addition, subtraction or fill-in-the-blank questions — it's all in one! Absolutely excited about it!"
"A little small for younger children. My five year old cannot make her numbers fit in the space."
"Worksheets from a computer work fine, but there is something about a child rolling out their own math problems that changes the dynamic entirely. This stamp generates a fresh set of problems with each pass."
"This is pretty good, and it definitely has its uses. This palm-sized roller can stamp out a seemingly infinite variety of arithmetic problems, which is great for practice worksheets and speed drills."
"My oldest is in third grade and loves it. My middle kid is benefiting already. I've used it myself as a review. Truly worth every dime!"
"The teachers I bought these for love them. I just wish they had division on them, and better instructions on how to apply ink."
"Excelente, muy práctico para el estudio de los niños." (Excellent, very practical for kids' studying.)
"Super easy to implement for early finishers! My only complaint is you need to press down hard for it to stamp evenly. Overall a great product! I use it in my third grade classroom."
"Works as advertised — just click the button every few problems so it doesn't repeat. I do small rows and click between each one. Works great."
Questions parents ask
What ages is it for?
Designed for kids ages 5–10 (Kindergarten through 3rd grade) practicing addition, subtraction, multiplication, and fill-in-the-blank. Not for children under 3 due to small parts.
Is the ink safe for kids?
Yes. It uses non-toxic, water-washable black stamp ink. It arrives pre-filled and includes a refill bottle, so there's nothing messy to set up.
Does it include division?
No — this model does Addition, Subtraction, Multiplication, and Fill-in-the-Blank. Fill-in-the-blank (like ▢ + 3 = 7) builds stronger number sense than rote division drills for this age group.
Will my child just see the same problems?
No. Each mode generates 400+ combinations (1,600+ total). Press the button to reshuffle the numbers any time, so practice stays fresh.
What's in the box?
The roller stamp pre-filled with ink, the yellow product box with a QR authenticity code, and one ink refill bottle for long-lasting use. Everything included — no extra purchases needed.
How does it work?
Turn the roller to choose a problem type, then roll across paper to print a fresh row of problems. After adding ink, roll 4–5 times to let it spread evenly, then it prints smoothly.
How does the free grading app work?
Scan the QR code on the box to open the free GoldenEgg grader in your browser (no download). After your child finishes a page, take a photo and the app instantly checks every answer and gives a score. The stamp itself stays 100% screen-free for your child — only the adult uses the phone.
Which color should I get?
Classic Blue and Pretty Pink are identical inside — same four stamp faces, same ink, same results. Pick the color your child will love most.
