Self Inking XY Graph Stamp, Clear and Aqua Blue, Inch Measurement (CoordiMate)

I *love* this graph stamp. I found it when I was teaching algebra to college students. They would geek out when I’d use it in class. My colleagues would geek out. My own kids and tutoring students think it’s the most amazing device ever created, plus fun! I bought plenty of these as gifts for friends, colleagues, and students.I should’ve bought more, as it seems the company’s no longer in business. WHY?!?!?! This was a genius idea.Mine’s lasted a few years, but if it goes out, I’ll have to steal back the one from my kid.COME BACK, COORDIMATE!!!!

This little tool helps eliminate the tedious task of drawing graphs that involve an x and y axis. It would be nice if it also had a grid pattern, but it gives me as much as I would do by hand. It makes nice crisp lines as long as you don’t press down too hard.

My kid hates the time it takes to draw the graph while doing Algebra. This has cut down the procrastination time and the time it actually takes to do the homework.

This is a very useful item for school, it saves time and makes it easy to use on tests and when taking notes. I gave it 4 stars because it's too expensive for what it is.

How did I get through my math classes before this! This little stamp is amazing! Takes out the hassle of having to draw countless graphs. I'm a computer science student. As part of my major I have to take a lot of math classes. This stamp is thing I never knew I needed, and now I can't live without it. Size is big enough to graph yet small enough so that it doesn't take up much space. Lines aren't numbered so you can count by any number to accommodate large plotting points. Ink dries very quickly by the time you grab your pencil to draw on it, and best of all it doesn't smear when you erase. My favorite part is that you can refill it with ink from your local arts and crafts store. This is a huge money saver. One of the best things I have purchased on Amazon. I highly respect it to anyone who has to graph something. Maybe a suggestion for the creators would be to add a bigger size just for those cases in which you need a lot of detail in your graph. Fast shipping too! Got mine 3 days after purchase.

Retired math teacher that tutors. I saw this and snapped it up. It's a great idea for kids when they start graphing systems of equations and inequalities and more. Now, they have no excuse to make sloppy, rushed graphs!

I teach math and I tutor often. This stamp is prefect for everything from detailed graphs to quick sketches. It has helped many of the students I tutor who previously struggled to draw an accurate graph and make connections between the graph and the equation.

I was hoping that this tool would save time for kids when graphing on a coordinate grid. Most of my students don't bother with a ruler and I thought this would be good for accuracy. It would work great if you were using lined or blank paper, but if you are using grid paper then the stamper is really hard to place and it would take less time to just use a ruler for the axis! Don't buy it if you are using grid paper. Otherwise, it would be helpful.
