for reasonableness
 multiplying and dividing by the reciprocal (key
vocabulary) yield the same results
The student will be able to:
 follow procedures to multiply and divide fractions
with precision
 find the reciprocal of a fraction
 rewrite mixed numbers as improper fractions

write a story context to demonstrate multiplication
and division problems
