I use this bingo board often in my class. I printed a class set on bright colored card stock then laminated them so students can use them over and over with dry erase markers. This is an easy and fun way to add an activity to your lesson. A simple way to use it, is to have students complete a work sheet and then put their answers on the board. You then call the correct answers. It turns a boring worksheet into something fun! Every classroom should have a set!
