An intervention to help teachers struggling with the “classroom from hell.”

$20.00 tax incl.


Think of your classroom. If you can label one third of the students as having very difficult to extremely difficult behaviours then this strategy will help.

“The more difficult or aberrant a child’s behaviour the greater their plea for help.”  Wilson McCaskill

Critical Mass is a long term strategy requiring commitment and planning by the classroom teacher.

Although it is not a quick fix it can, if the teacher perseveres, create significant improvements within the space of a term.
