 Connect Three from Nrich Maths  Be the first to connect three numbers on the game board. Roll dice with positive and negative numbers to make addition or subtraction expressions to claim spots on the board.
 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.
 HexaCounters from Justin Aion  Justin uses a manipulative called HexaCounters to model addition of integers in a variety of methods.

 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.
