Solving Word Problems and Equations

Mrs. Lopez guides students through solving word problems using two-step equations. The lesson covers setting up equations from word problems, solving for unknowns, and verifying solutions. Problems include arranging posters on a wall, placing sconce lights, calculating ages of sisters, and determining costs in a music store. The session concludes with a vocabulary review.
