We worked on Ben's assignment for today that dealt with solving systems algebraically by substitution or elimination. Ben had remembered what I had told him last week about working through the problems step-by-step and writing each step down clearly - by the time we reached the end of the assignment sheet, Ben was whizzing through the problems. I was also very pleased that Ben asked a couple of questions during the lesson, and they were absolutely the right questions to ask, which shows he's thinking through the problems in the right way.
