 123 Switch! from Tom DeRosa  A card game using integers. Students use their cards to make a true equations. First player to get rid of all their cards wins.


 Integers Clothesline Game from Andrew Stadel  Build and strengthen conceptual understanding of adding & subtracting integers using an integer clothesline. Teams work to land on a target number first by adding or subtracting integers on a number line.

 Which One Doesn't Belong  Ask students to select one of the four numbers and justify why they think it is different than all the rest. There are no wrong answers as long as a justification accompanies it. Check out http://wodb.ca/ for lots of additional suggestions.
 Integer Bingo from Ilona Vashchyshyn  Draw random integers (4 to 4) and add them together. If the sum is on the student's bingo card, they can cross the number off. Start with random bingo cards for the first round and then let them make their own bingo cards for the second round. Great integer addition practice as well as a bit of probability.


 Zip, Zilch, Zero Card Game from NCTM Illuminations  Players try to make a sum of zero using cards 2 or more cards from their hand. Black cards are positive integers and red cards are negative integers. Students build understanding of adding integers while playing this game game involving both strategy and luck,

 Adding and Subtracting Directed Numbers from The Mathematics Assessment Project  This lesson unit helps students to add and subtract directed numbers (positive, negative and zero) with understanding. It introduces the charge model for directed numbers and asks students to match diagrams with calculations and produce missing diagrams for the remaining calculations.

 DownsideUp from Mathelicious  Happiness, and the lack thereof, is on the mind of every student in our classroom. As a result, students often have strong opinions about happiness, sadness, and the space between. Do bad days make good days feel better? Is it better to have a steady, small level of happiness, or to swing wildly from elation to misery and back? In this lesson, students use integers to compare good and bad days and use absolute value to explore what happens when we reinterpret negative moments in a more positive light.
