This prompt comes from division = subtraction? on Don Steward's website. Students notice the properties of the prompt: the mixed and whole numbers are the same on each side of the equation, but the operation is different. Finding another example of the same type, however, can prove challenging for students. By focusing on the mathematical structure of the equation, the teacher can support the search process.
In the next phase of the inquiry, students might verify the equation is true before using its structure to search for more examples (see below for two more).
