She has a large classroom with many distinct "areas" which afford many opportunities to explore and discover. Every day during "Work Time" Theresa allows her students to choose the area in which they want to work and the activities that interest them (Benenson, Neujahr, Bennett, Meade, Diez, Flores, Gatton, Gonzalez, Luongo, Odinga, Piggott, Purnell, Rivera, Skea, Smith, and Williams, 1999, p. 63-64 ). Theresa reported on how testing the strengths of shopping bags led to repair and redesign of bags and other objects ( p. 67-71 ).
