Need to fill a little time? Is it a few days before winter break? Do you need a great way to ensure the kids are busy for a substitute? I use this type of puzzle for every such occassion. It can be modified for any age or subject. My students eat these up! (Fill the blanks with words that match the letter and topic.)
I've been teaching mathematics, international studies, and media design since 1998 in an urban district located in the southeast region of the USA. Before becoming a teacher, I worked as an electrical engineer for several years.
