## Reflection: Relevance Three Stacks - Section 5: Continued Practice

There are three examples of student work in the resource section of this reflection.

Student A:  This student is still counting out each number and then counting all to get a total.  You can see that she had marks on her paper for each number and then erased them, and wrote her total.  She is someone who just recently got the 1:1 correspondence and is not ready to securely make the leap to the counting on stage.  She will need continue intervention and modeling of the counting on strategy.  It is developing for her but she just needs more time.

The other two (B and C) are secure with this activity and secure with the counting on process.  B is abel to solve them in his head, keep the numbers in there, compare ether, and then circle the set that is the highest.
