This post has a free Halloween bingo class or group game with bingo cards, cards for the caller, and makers in a PDF printable that is 26 pages. It also has links to other popular October freebies on this blog. The pictures in this game are children wearing Halloween costumes, candy, and non-scary decorations for this event. I have just updated this game somewhat so I am writing a blog post.
The cards for the caller are 4 to a page as shown in the following picture.
And there is a page of marker pieces for the children to use to cover the squares. They just mark the pictures and there are no letters or numbers to be concerned with, which is nice for young learners.
