Good afternoon folks
The winter that was not, (at least for us in Southern Ontario), has gone, and we are having double digit temperatures.  I have not been working on this blog, due to the fact I have been extremely busy working on my book.  There is now a whole series of Castle Wall workbooks (addition, subtraction, multiplication and division) on Amazon.  Coming out shortly is a book full of addition games, that the only thing you need in addition to the book is a couple of deck of cards.
