Though it is not actually in the teacher area, educators should remember the little tool icon in the menu.
The Student Toolkit area is a place for students to find tools that could help them in Social Sciences, on the Exam, while researching, etc. Of coursem teachers can and should use some of these great tools too!
Regarding the Intellectual Operations and the resources above, you won't likely find our icons there. If you are looking for our various I.O. icons, and many new icons too, visit the working document at Iconography used in various LEARN LES and Tasks.
