One thing that makes a search like this more difficult is that many sites are either directories or attempting to sell a calendar program. The latter usually have something free to give away, but if they want you to buy a program the one they are giving away is pretty generic. Don't waste time trying to make the free one work if it isn't perfect on the surface. There are other choices that are completely free. You may have to try several options, but if you are patient and persistent you can find a truly free and printable calendar.
These printable games aren't difficult to find or to create. There are plenty of sites on the web that will allow users to download and print their own Halloween word and math puzzles. All that is needed is a printer and a computer with access to the internet. When performing a search for these puzzles it may be easier to type in a general phrase such as, 'printable puzzles and games' rather than looking for Halloween games in particular which would considerably narrow your search. Many sites will have a plethora of different holiday themed puzzles to choose from and Halloween is certain to be among them. You will also find that there are lots of sites that have programs allowing the users to create their own puzzles from words of their choosing.
