Reflection: Debate Number Trick - Section 2: Explore

 

Number trick made them stop and think. It was a game that really made them think. I heard steps being repeated and saw erasing as students tried to work through it. Creating their own original number trick was an interesting concept. Students wanted to stop if the trick didn't give the answer they wanted but gentle pushing seemed to encourage them to keep working at it. Perseverance is not always the first option.
