Students drag number tiles to make both sides of a scale equal a target value in this interactive equation-building activity. Learners apply addition, subtraction, multiplication, and division to a visual model of equivalence, revising their tile placement until both sides of the scale balance. This activity supports TEKS covering multi-step problem solving and operations across grades 3-5 (3.4.A, 4.4.A-E, 5.3.A, 5.3.B).
Skills: equation building, operations fluency, mathematical reasoning, self-checking. Grades 3-6.
