A first step toward establishing a respectful classroom learning community is acceptance of all ideas and answers—regardless of any obvious errors. Rich mathematical discussions cannot occur if this expectation is not in place. We must remember that wrong answers are often rooted in misconceptions, and unless these ideas are allowed to be brought to the forefront, we cannot help students confront their thinking. Students who are in safe learning environments are willing to risk sharing an incorrect answer with their peers in order to grow mathematically. It is important to model and expect the acceptance of all ideas without derogatory comments. As educators we can model this by recording all answers to be considered without giving any verbal or physical expressions that indicate agreement or disagreement with any answer. The teacher may need to practice having a “blank face.” Students look to teachers as the source of correct answers. Part of building a safe learning community is to shift this source of knowledge to the students, by equipping them to defend the thinking behind their solutions.

① to have students justify solutions instead of relying on teachers
② to have teachers explain solutions before students defend them
③ to let students record all answers without correcting errors
④ to make teachers the final source of mathematical discussions
⑤ to encourage students to avoid sharing incorrect answers publicly

The usual intercity traveler moves slowly through the station area. The passenger may not be familiar with the routine, have baggage to handle and check or retrieve, have a long wait for connections or delayed trains, and may require information, food, and a comfortable place to sit. Commuters, on the other hand, are familiar with the route through the station, have little or no luggage, and are usually in a hurry. They want direct access to or from local streets and transport. These two types of traffic should be kept separate to avoid conflict and confusion. In some large stations such as Grand Central Terminal in New York City, commuter and intercity trains arrive and depart on different levels. In smaller stations, separate platforms should be used and traffic routed so that the two lines of movement do not cross. In some instances, separate stations are in use. Clear and concise direction and routing signs and other means of channelization are desirable.

① to divide commuter and intercity flows into distinct routes
② to give both traffic types the same station access
③ to provide intercity travelers with more food and seating
④ to route all station traffic through local streets quickly
⑤ to help commuters handle baggage and delayed connections
