1 Adding Integers with Tiles Student Expectations: 7 th 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 = = + 3 The University of Texas at Dallas +3+3

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

5 ADDING INTEGERS The University of Texas at Dallas = ? + = = = ? ANSWER = = + 1
