Although it is easier for some students if you do one step at a time you're
right about regaining their attention for the next step. I write the steps
out and display them for the class. For my K's I draw pictures of what to
do (a crayon, scissors, glue or even a picture of folding the paper).
Their classroom teachers couldn't believe they could follow the
instructions. My first grades can read some, but I draw for them. too.
Naturally, I write for my 2-5 students, but we go over them. We always
read it together as I demonstrate each step, then we read it together
before they begin.
