Integer War - This is a great way to reinforce what an integer is and help the students to quickly realize how to solve and answer integer problems. Plus a integer game is a better way to reinforce the concept compared to using integer worksheets for kids. A standard deck of playing cards is a great resource for reinforcing integer concepts and operations playing variations on the classic card game "War".

Integer Card Game - Two students play together. They both draw two cards and add them, then play again with subtraction. Whoever has the higher number collects all four cards. -- Would be great especially for students who are having trouble understanding negative numbers/greater than and less than/adding and subtracting quickly.
Give each student colored index cards/post-its for their work space. During independent work time or group work, the students use the cards. A teacher I used to work with put red cards on popsicle sticks at the student work centers & prompted them to hold it up when they needed help, rather than calling out. Her classroom was always so quiet!
