BTC Tasks
Building Thinking Classrooms involves using highly engaging thinking tasks to initiate a culture of thinking. At first, many of these are non-curricular, but the culture of thinking is developed through their use so that curricular tasks then also become highly engaging! Below are some sample BTC tasks organized by grade band that are both non-curricular and curricular. See also the Card Tricks and Numeracy Tasks pages and BTC Books for more BTC Tasks!
