There are four files in this zipfile: two ActivInspire Math Warm Ups (for Promethean Boards) and two Powerpoint Warm Ups. The PPT files have a white border around the edge because I just converted them from a .flipchart file to a .PPT file.
They should take you through October. I have the students solve the problems independently for three minutes- then show and discuss with their teammates for one minute. Then, I call a random student up to the board to use math talk to explain and solve the problem on the Promethean Board. If you enjoy this file, please leave feedback. Also, consider donating to my classroom at http://www.donorschoose.org/we-teach/384973.-245268425?historical=true !
