Reflection: Modeling Use Number Line for Subtraction - Section 3: Independent Practice

 

It is very important to model to your students the exact moment of when to start counting as they move their finger across the number line to subtract. Watch the video, Trouble with number line video, of one of my students presenting this common mistake and my reflection, number line reflect part 1 and number line reflect part 2, for the task.

  Modeling: Right on the dot!
