What do you	What do you
notice?	wonder?

1.	Create your own addition and subtraction problems using these data. Consider all the unknown values and actions possible in problems.
2.	Test strategies you know from the anchor charts to solve the problems you create.
3.	Research and share new data to include and ask questions about.
