STOP
Walk around the room and look at how others ordered the standards

Take a broad look at the clusters
- What common themes do you notice?
- What’s missing?

“There’s no place value in Investigations- we need to
supplement”
Wide-Spread Misunderstanding+ Major focus of Common Core We better find a solution for this!

Does your strategy fall into one of these categories?
- Making an easier problem- Adding up
- Subtracting in parts- Algorithm

With these types of numbers which strategy shows the deepest understanding of
number? The least? Order them.- Making an easier problem
- Standard Algorithm- Adding up
- Subtracting in parts

Where was the place value in this?

We just did a subtraction problem. How does this connect to the standards/clusters in the Common Core?

A Second Look…
Read the clusters again and discuss
- Where do major changes take place?- What supports might our students
need? Our teachers?

A teacher comes to you and says, “There’s no place value in
Investigations”. Create a response (With a partner) include examples and
representations.
