With a partner…

Order the Common Core NBT (number and operations in base ten)

standards from Kindergarten to 5th grade.

STOP

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

Let’s make sure we’re all on the same page…

Take a broad look at the clusters

- What common themes do you notice?

- What’s missing?

A Vertical Look at Place Value

Does your strategy fall into one of these categories?

- Making an easier problem- Adding up

- Subtracting in parts- Algorithm

A Vertical Look at Place Value

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

How did you Solve? 321-193

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?
