Students explore integer addition and subtraction using the zero pairs visual model. Learners drag positive and negative counters onto a workspace to see how opposite pairs cancel to zero, reinforcing integer operations. Supports TEKS 6.3.D and aligns with Common Core 6.NS.C.5, 7.NS.A.1c, 7.NS.A.1d.
Skills: integer operations, zero pairs, number sense, visual modeling. Grades 5-7.
