E -6000 works well-just make sure to use in well ventilated area-really
not an adhesive for kids to use. The other thing we use is 3M's spray
adhesive- again well ventilated- not for children. GLues are tricky in a
classroom setting. I probably wouldn't use much other than white glue &
gluesticks in elementary rooms-would you?
You can get E-6000 for $2.70 a tube (min 12 tubes) from Rings & Things-
(or $4.00 a tube) does not include shipping
