Brain teasers

The Raygor Readability formula where matching text to appropriate reading level was interesting. At first I thought, hey what can I do if a student is already placed in my class and is not up to par with what is expected of him. Now I understand that when this entire DI program is over (at least for the elementary students), I can look into the formula and determine whether a certain student has been placed at the correct grade level. The cloze practice was another interesting testing program BUT I wonder what kind of testing is used here in Guam for testing our high school students? The brain stretchers were challenging for me and look forward to doing the rest of the brain teasers.
