Correspondents frequently ask:
Do you have answers to (this or that worksheet on the Web site)?
Typically, no. I’m sorry, but I don’t have the time or interest to write up answers.
The exception is that if the activity appears in a book, the answers are indeed written up, as the publisher usually demands it. (Even then, I usually try to get someone else to write them.) They can be found in the back of the book, or in its teacher’s edition. If the book is still in print, you’ll have to buy it. If not, you may be able to find it on my Web site.
