Setting the stage

Structural Thinking (MP7)
Attend to....
Organization and Properties of Number and Space

Ask Yourself...

• How can I "chunk" this to make sense of it?
• How can I "change" the form to make it easier to work with?
• Can I "connect" this to something else I know?
• How can I use properties to uncover structure?

"Put into Action"

• "Chunk" complicated objects
• "Change" the form of objects
• "Connect" math ideas and representations
• Recall and use properties, rules of operations and geometric relationships

Find the value of the expression "in your head."
29 x 4

I can break 29 into "chunks"...
29 x 4
4 x 29
4 x (20 + 9)
4 x 20 + 4 x 9

I can "change" the form of
4 x 29, and then change the form of 29...
4 x 29
29 x 4
4 x (30 - 1)
4 x 30 - 4 x 1

I can "connect" multiplying by 4 to what I know about quarters...
29 x 4
25 x 4 = 100
4 x 4 = 16
4 x 25 + 4 x 4
