A 3-step technique used by Montessori Teachers for presenting new information to a child. 

In the first--the introduction or naming period--the teacher demonstrates what "this is.” (The teacher might say "This is a mountain” while pointing to it on a 3-dimensional map.) 

In the second--the association or recognition period--the teacher asks the child to "show” what was just identified ("Show me the mountain”). Finally, in the recall period, the teacher asks the child to name the object or area. Moving from new information to passive recall to active identification reinforces the child's learning and demonstrates her mastery.
