Develop Understanding

Today's Learning Goal: (G4,U4, L2,L5)

Round decimals to different place values and order them.

Today's Materials:

Laptop
Laptop charger
Pen/Pencil/Paper (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.

Jump Start: True or False - (5 min)

Decide whether each statement is true or false. Be prepared to explain your reasoning.
