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

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.

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.

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.

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.

This was a required purchase for Algebra for my son. He loved it and was happy that I purchased it for him.

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!

Nice concept but bleeds through notebook paper. Would have liked it better if it had less dark and bleeding ink. Honestly just draw the graph by hand it’s not that big a deal.
