Solve two-step word problems involving all four operations and assess the reasonableness of answers

In this lesson, students continue solving two-step word problems involving the four operations. (For example, "Miss Lianto orders 4 packs of 7 markers. After passing out 1 marker to each student in her class, she has 6 left. Find how many students are in Miss Lianto's class.") Working in small groups, they model and solve an assigned problem, and then present their solutions to the class.
