5th grade nonfiction unit price at the grocery store 206 words

The Big Bag That Cost More Per Pound

Maya and her uncle stood in the grocery aisle, looking at two bags of rice. The small bag held 2 pounds and cost $3. The big bag held 5 pounds and cost $9. "The big bag is the better deal," said Maya. "Bigger bags are always cheaper." Her uncle smiled and suggested that they test that idea with a little careful math.

He showed her a useful tool called unit price. A unit price tells what one unit of something costs, such as one pound or one ounce. To calculate it, you divide the price by the amount. For the small bag, $3 divided by 2 pounds is $1.50 for each pound. For the big bag, $9 divided by 5 pounds is $1.80 for each pound.

Maya was surprised to discover that the big bag actually cost more for every pound. The smaller bag was the better deal, even though it held less rice. Her uncle explained that a large package is not always the cheapest choice. Many stores print the unit price on the shelf tag, in small letters under the big price. Now Maya looks for it every time she shops. Comparing unit prices is a fair way to judge packages of different sizes, because it measures all of them by the same unit.

Maya and her uncle paused in the crowded grocery aisle, comparing two bags of rice. The smaller bag held 2 pounds and was priced at $3, while the larger bag held 5 pounds and was priced at $9. "The big bag is obviously the better deal," Maya declared. "Larger bags are always cheaper." Her uncle smiled and replied, "Let's find out whether that is true by using a little math."

He introduced her to a tool called unit price. A unit price tells you what a single unit of something costs, such as one pound or one ounce. To calculate it, you divide the price by the amount. For the small bag, $3 divided by 2 pounds comes to $1.50 for each pound. For the big bag, $9 divided by 5 pounds comes to $1.80 for each pound.

Maya was astonished. The big bag actually cost more for every pound, so the smaller bag was the better deal despite holding less rice. Her uncle explained that a large package is not necessarily the cheapest one. Many stores print the unit price on the shelf tag, usually in small letters beneath the big price. Maya now checks for it every time she shops. Comparing unit prices is a fair way to judge packages of different sizes, because it measures every one of them by the same unit.

Ideas for class

  • Before reading, put aisle, unit price, divide and package on the board with their meanings from the Words to know section and have students predict what the text will be about.
  • Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 2 minutes to read aloud.
  • Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
  • Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
  • Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
  • Print the student copy for independent work and keep the answer-key copy for yourself.
