During the class, students can get in groups and organize themselves in order from smallest to largest without talking. After they've organized themselves numerically in their groups, have one group at a time come up front and form a human number line. In Algebra II, you can include imaginary numbers or give them two coordinates with rows and columns in a matrix. In trigonometry, I use radian measures and polar coordinates. In geometry, you can use types of congruent and similar triangles, polygons or angles.
Students learn mathematics while the teacher creates a new seating chart.
In order to spend less time going over homework, give each row a blank transparency sheet and an overhead marker. Have students write their work or answer to any homework problem you want to discuss. Students can do this while the class is working. Then have students present their work or the teacher can display it during group work time for anyone who needs to check an answer. You can also give the transparency and marker to the students the night before, and they can be ready at the beginning of class to discuss their work.
