Describe the types of problems that should be included on the practice worksheets for Format 8.3: Subtraction with Renaming
What will be an ideal response?
The examples on the practice worksheets for Format 8.3: Subtraction with Renaming should include a mix of the current and previously introduced types of problems. When problems requiring renaming from tens are introduced, about three-fourths of the problems on a worksheet should involve subtraction and one-fourth addition. Of the subtraction problems, only about half should require renaming. When problems involving renaming from hundreds are introduced, about half of the problems on a worksheet should require renaming from hundreds, about a quarter of the problems should require renaming from tens. The final quarter should include subtraction problems that do not require renaming and addition problems.
