EngageNY 60 min(s)

In this lesson, students solve two-step word problems using all four operations. (For example, "Joe has $173 in the bank. He earns the same amount of money each week for 7 weeks and puts this money in the bank. Now, Joe has $208 in the bank. How much money does Joe earn?") In the process, they analyze each problem using tape diagrams and write equations with a letter representing the unknown.
