About
123.14 is a space in the Marais given over to math, where kids work in small groups on a program the team writes themselves. Each session opens with mental arithmetic, brings in one new idea, then moves to varied, offbeat exercises; each of the year's five big themes ends with a quiz. Kids are grouped by level, taught by a qualified teacher, and finish the year with a filled-in workbook.
