What NOT to Do with Dry Erase Markers!

Ya’ll are going to love this one!!  Just when the custodian was fussing about the painters tape on the floor and my door being open…I did a doozy….

Since I have been working with lots of intervention groups, I am trying to teach them concepts in a short amount of time while I have them out of the classroom.  Yesterday I thought I would work on some measurement estimation.  I gave the students 3 choices to estimate the length of a car.  12 inches, 12 feet, and 12 yards.  Since these students don’t have a lot of experience with measurement, I had many students say 12 inches or 12 yards so….

I saw the need to draw on the floor with a dry erase marker of course!  I drew a 12 inch line with a ruler, a 12 foot line with 12 rulers, and a 12 yard line with yard sticks so students could see the difference.  They were easily able to see that the 12 foot line was the best estimate.

Then it came time to rub the line off the floor and whadaya know…but…you guessed it…the dry erase marker wouldn’t budge off the floor!  AAAAAAAAHHHHHHH!  Oh, no!  Well, after soliciting some help
someone suggested dry erase board cleaner…and it worked! YAY!

Now if I had it to do over, I would still write on the floor because it didn’t take too much elbow grease to rub off–and the floor is like a new giant white board with endless possibilities!
