Given real-world problems, students write & solve two-step equations. Because students naturally gravitate towards writing equations that reflect how to go about solving the problem rather than a direct translation of the word problem into a number sentence, students are given half of the equation (the "total") and must write the expression that would make the equation true.
May be implemented in various ways, such as independent or collaborative activity, or may be used in math stations or as guided instruction.
QR codes are a wonderful form of instant feedback for students. Students may compare their equations/solutions with the correct answers to build student confidence when achieving correct solutions, while also challenging students to understand where they went wrong when equations and/or solutions are incorrect.
