A great worksheet for when students finish work early, warm ups, or sub plans.
Display a 4X4 grid of various letters and students can use this worksheet to write down words that they find by connecting the letters in the grid. You can make it a class, group, or partner competition.
I actually have a laminated grid on my classroom wall that I write letters on every time there is a possibility of students finishing early. They know that Boggle is always an option when they run out of work to do :)
