This product includes 3x3 bingo boards as well as 4x4 boards with blank clocks that allow students to draw the hands and customize the game to your needs. This allows you to assess students knowledge as they create their own game boards! It also allows you to play with various skill levels such as: times to hours, half-hours, quarter-hours, or even 5 minute intervals. I have used this with Kindergarten up through 5th graders as review and additional practice. Teacher instructions included. Please feel free to contact me with any questions!
