  1. Adding Integers with Tiles Student Expectations: 7th Grade: 7.1.2C Use models, such as concrete objects, pictorial models, and number lines, to add, subtract, multiply, and divide integers and connect the actions to algorithms.

  2. ADDING INTEGERS • We can model integer addition with tiles. • Represent -2 with the fewest number of tiles • Represent +5 with the fewest number of tiles. The University of Texas at Dallas

  3. ADDING INTEGERS • What number is represented by combining the 2 groups of tiles? • Write the number sentence that is illustrated. -2 + +5 = +3 +3 The University of Texas at Dallas

  4. ADDING INTEGERS • Use your red and yellow tiles to find each sum. -2 + -3 = ? ANSWER = -5 + -2 + -3 = -5 The University of Texas at Dallas

  5. ADDING INTEGERS -6 + +2 = ? ANSWER + - 4 = -6 + +2 = -4 -3 + +4 = ? ANSWER +1 = + -3 + +4 = +1 The University of Texas at Dallas
