When solving temperature problems with negative integers, number sentences may be mathematically equivalent but not contextually equivalent.
Jeffrey M. Choppin, Carolyn B. Clancy and Scott J. Koch
Allowing students to reason and communicate about integer operations, or any idea, before these ideas are formalized can be an important tool for fostering deep understanding.

Teachers can benefit from productive and manageable suggestions to align instruction to the intention of the Common Core's Standards for Mathematical Practice.
Juli K. Dixon and Jennifer M. Tobias
Anticipate and address errors that arise when fractions are placed in context and illustrated with models.
