Self Inking XY Graph Stamp Clear and Yellow, Inch Measurements (with Black Ink)

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!!!!

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.

The lines are crisp and sharp, the perfect size and shape for making graphs in my math notebook. I can use the stamp and erase any mistakes (after the ink has dried) and the plane stays where and how I need it. The stamp fits perfectly in my pencil case.

I love it and my students love it. It’s easy to use. It gives you a nice clear graph. My students prefer it and will often ask for the graph stamp. The stamp is just an x and y axis with little notches along the axis. Basically just a beater version of what my students would draw.

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.

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 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.
