Why We Shouldn't Use Gradual Release Often in Math Class

Gradual release is a method of teaching where the teacher starts out by showing how to do a procedure. (I do.) Then, the class works on a problem together. (We do.) And then finally students do a problem themselves. (You do.) The teacher is gradually releasing the responsibility to the students, the responsibility of getting an answer.
If we look at the Standards for Mathematical Practice, gradual release is not conducive for most of them.
