## Reflection: Intervention and Extension How Many Dots? Day 2 - Section 2: Station Time

This is the 2nd day of these station activities.  After yesterday's lesson, I could look at completed work and observations from yesterday's station activities to decide how to differentiate.

In the section resource, you will find a piece titled intervening for understanding. This student represents someone who is still trying to develop an understanding of the concept.  In this case, I gave her a sheet that just involved adding ten.  You can see on her sheet that I drew arrows above her first number.  I spent some time talking about the number representing the sticks that she had dropped.  I then used this to have a discussion about adding another group of ten and how it would be represented.  This is a child that will need me to continually touch base with her during this unit.

The other example is of a student who needed a challenge.  I wanted to see how well he could subtract multiple groups of ten from a number.  The blank sheet allows me to differentiate for each student.
