Structures and Patterns
As students grow in comprehensive ability the structures become more complex.
Teachers facilitate by leading discovery through example and problem-based learning.
I can see and understand how numbers and space are organized and put together as parts and wholes. Students can demonstrate through performances of understanding that can vary depending upon the type of problems involved.
Example of a Rich Task
Driving by a farm. I saw chickens and
cows. Through the fence I counted 40 legs
and 15 heads. How many chickens and
cows did I see?
A furniture maker was putting stools and
chairs together. The stools were the three-
legged kind and the chairs had four legs. If
the seats were the same for the stools and
chairs, how many of each could he make if
he had 21 seats and 72 legs?
