The addition and subtraction quiz.

This quiz will be mainly on the CGI problem types, and computation strategies.

Stuff to know:

• Be able to write and identify simple addition and subtraction word problems by their problem types.
• Know which problem types are more difficult
• Know the typical direct modeling and counting strategies
• Know the 2-digit addition and subtraction strategies we discussed.

Because this quiz involves more specific memorized information than most, you may bring 1 page (single sided) of hand written notes for the quiz.

*3-digit addition and subtraction, including standard algorithms will be on the final exam, but not on this quiz.
