This week we learned a great way to distinguish between the different options of how many solutions exist when working with two equations in a system of equations. I was working with a group of students who were struggling to really see what they were trying to do when identifying how many solutions are possible. They just didn’t understand what it meant for a system of equations to have one solution vs. no solutions vs. infinite solutions. So, we started adding the strategy of hand gestures, and it really seemed to help some of them understand this topic differently.
