Easier Problem

Cindy and Jeff were camping with their family. They and their dad went to the water pump to bring back water to their camp site. Dad had filled 6 buckets

without handles. He labeled each bucket with the fractional amount of water each bucket held. The amounts are shown below.

Cindy and Jeff each have a bucket the same size as the buckets that Dad filled, but their buckets had handles. Their job is to pour all the water in the 6 buckets into their 2 buckets and carry the buckets back to camp in one trip.

All the water in the 6 buckets without handles must fit into Cindy’s and Jeff’s buckets.

Show which buckets Jeff should pour into his bucket. Show which buckets Cindy should pour into her bucket. Show how you determined your answer.

Name__________________________________Date_____________________________ (25A)Harder Problem

Dean and Scott were camping with their family. They and their dad went to the water pump to bring back water to their camp site. Dad had filled 6 buckets without handles. He labeled each bucket with the fractional amount of water each bucket held. The amounts are shown below.

Dean and Scott each have a bucket the same size as the buckets that Dad filled, but their buckets had handles. Their job is to pour all the water in the 6 buckets into their 2 buckets and carry the buckets back to camp in one trip.

All the water in the 6 buckets without handles must fit into Dean’s and Scott’s buckets.

Show which buckets Dean should pour into his bucket. Show which buckets Scott should pour into his bucket. Show how you determined your answer.
