And instantly my lesson just got better. I get to use Desmos for the first time with my freshman and we are just beginning!
Here's a general outline and my thought process.
I will ask students to share out some answers and I will write them on the board. I will have one chrome book per group of three students and ask them to each take turns typing in an expression from the board (I'm thinking 6 so each student types in 2 and purposely include wrong ones). But what if I don't get very many answers?
I will ask them what they notice as they type in each equation.
We will discuss the connection between the expression and the line.
Some kind of work happening, either with Algebra or Desmos leading up to the fact that they graph two parallel lines which have no intersecting solution and how they simplify to the same slope with different y-intercepts.
Is that it? Now we just practice?
What are some good questions I can ask? What needs to go in their notes?
