R Hansen says: >Connecting multiplication with grids of dots is going to take more than one pass and connecting multiplication with pictures of dots requires a multitude of realizations. All of this will require many pictures and then there is some minimum number of pictures required (in a test) to ensure fluency. I see two types of weariness. Type A when the student doesn?t get it and becomes weary of trying and failing and type B when the student does get it and becomes bored of the exercise. I haven?t found students to be bored with the exercise at 10 pictures. At 100 for sure
One child may get a particular concept immediately, another may need an entirely different explanation because of some hang up.
