The seventh graders are having some correctness problems on their 100 word explanations of various topics in their packets. They select 35 points' worth of material to do, their choice, from over a hundred points' worth of choices... So, in the past week, write/right, hear/here, their/there/they're have all appeared and been discussed. Today, it was to/too/two. The student "had to questions" to answer... When I asked him to tell the difference, he found the number just fine, but was stuck trying to explain the difference between to and too.
Finally he said, "I want to go, too."
"Which choice is that?" I prompted, seconds before the bell.
"Number TWO!" he called back as I dismissed them.
