Instructional Ideas

• Save paper and write the sentences on the board for learners to correct in front of the class

Classroom Considerations

• Some sentences have more than one answer, but the answer key does not list them all
• Best used as math practice rather than grammar or spelling practice

Pros

• Comes with an answer key

Cons

• Directions are unclear
• Does not clarify special cases of when to write numbers in word form or standard form
