Direct instruction
The learning intention was to Apply Linear Systems of Equations to Solve Problems. Our class has been using Teacher Desmos to support the learning for this standard - Systems of Equations 2.14.
This video shows the students working through the Racing Dots activity.
Reflection
This lesson did not go as well as I had hoped. Some of the students found the context abstract and next time I will do the Playing Catch-Up activity first, as I think students will find this easier to relate too. I also need to bring the class in more often, when using activities such as this, because there is no instant feedback. I found this activity really powerful in how it related equations, graphs and tables - this was a huge positive that I took out of this lesson. Another thing to keep in mind is that these activities can take quite a while. Next time I will try the Teacher Desmos activity in a double period.
