My dd's teacher sent home a note that every child needs one wet erase marker, for home use, to practice the 50 states and capitals. I can only find packages of 8 for $7.49. She just needs one. Can she just use dry erase? Much easier...

Wet erase will only come off when wiped with water and a towel, a wet wipe, etc.

We used to call them Overhead projector pens--Vis-a-Vis was the most common brand.

Can you split a pack with some other parents? But if it's just for home use, I don't see why you couldn't just use a dry erase.

*Eta: The wet-erase are better at not leaving residue. What is the marker going to be used on?

The teacher is sending home a laminated US map with no state names on it so the kids can practice before each test.

I'll have her try with dry erase markers and see how it goes. I don't know any of the other parents, and I don't have a need for those markers myself. But if the dry erase don't work out, I'll buy them. I just hate having extra "stuff" around. Maybe if I buy them I'll donate the rest to the teacher.

I'd bet that dry erase would work just fine. That spray on cleaner for dry erase boards usually helps when the build-up starts. Also, you could scan or make an extra copy of the map when you get it in case you have to make copies or get a new copy laminated.

I'd be with you on not wanting to buy a whole pack of overhead markers. That's really the only thing they're good for, and most schools have phased out use of overheads.

I think you can buy single ones at Office Max...the wet ones do come off easier and don't leave a mark.

Is the map something that will be going to and from school, or that she will have to transport somewhere?

If so then Id get the wet erase markers. The dry erase can smudge off in a backpack, if an arm or finger rubs against it, etc. So it could be smudged up and hard to read if the teacher needs to see it.

If it stays home 100% of the time then Id try the dry erase markers.

I just had to buy packs of the dry erase for both of my older boys school supplies and they were $5 a pack so not much less than the wet erase ones.

Try calling Office Max (or whatever a PP suggested) and see if htey sell single wet erase markers. Id imagine you could find single ones somewhere!

Office Max is where I went today, after not finding any at Target. But I can try Office Depot. I already have dry erase markers, so there would be no added expense there.

If the dry erase markers leave a residue, as they can on laminated items, use a 91% isopropyl alcohol. The normal 50% used for cleaning wounds won't work.

91% isopropyl alcohol will also take sharpie off of laminated items.

Don't get the "smell free" Expos. And Stick to black, green, or orange. In my experience, red, purple, and sometimes blue are harder to clean off without staining.

Please check with the teacher to find out why she specified wet erase instead of dry erase. I have had some materials before that ended up permanently stained by the dry erase markers. Wet erase rarely stain, though.

Is this something the teacher laminated herself? Or is it a product the school purchased? If it is the latter, the manufacturer may have recommended the wet erase marker.

I've ALSO used the isopropyl alcohol to get SHARPIE off things that nothing else could get off. I wasn't even using the 91%.
