### Jeffrey M. Choppin, Cynthia H. Callard and Jennifer S. Kruger

Student-generated algorithms, despite being inelegant and cumbersome, can nevertheless highlight a Common Core standard on rational number subtraction to show flexibility and understanding.

### Nicole M. Wessman-Enzinger

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.

### Jae Ki Lee, Kyong Mi Choi and Melissa McAninch

The L-shaped 2-5-3-7 algorithm, combining efficient Singaporean and Korean procedures with divisibility rules of primes 2, 3, 5, and 7, helps students identify LCMs and GCFs.

### Debra I. Johanning

Research on how students add and subtract fractions indicates that students struggle to understand various algorithms.

### Victor Mateas

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.

### Daniel J. Heck, Jill V. Hamm, Jessica A. Dula, Pippa Hoover and Abigail S. Hoffman

Three seventh graders, working as a small group in their math class, had a conversation about adding and subtracting integers. The students discussed the challenges they faced in the assigned task.

### Jessica Pierson Bishop, Lisa L. Lamb, Randolph A. Philipp, Ian Whitacre and Bonnie P. Schappelle

Reasoning about integers provides students with rich opportunities to look for and make use of structure.
