Develop Understanding

Today's Learning Goal: (G8, U3,L10)

  • Create a graph of a line using a verbal description of its features.

  • Describe (orally) the graph of a line using formal or informal language precisely enough to identify a unique line.

  • Generate a method to find slope values given two points on the line.

Today's Materials:

  • Laptop

  • Laptop charger

  • Pen/Pencil/Paper/Expo Marker (optional)

Please complete the Jump Start (activator). You have 5 minutes before we review. This is independent it should be silent.

Reminders:

1. Ready for class

2. No cellphones

3. Volume must be low.

4. Read and follow all directions

5.) Take your bag off and immediately begin the Activator.
