Unit prices

Explain that unit price is the cost of one unit of a product. For example, if a pack of 6 juice boxes costs $4.50, the unit price is $4.50 ÷ 6 = $0.75 per juice box.

Teach students that unit prices help compare the cost efficiency of similar products. A lower unit price indicates a better value.

Use examples from daily life to illustrate unit prices, such as comparing prices of different-sized packages of snacks or drinks.

Guide students through the process of calculating unit prices step-by-step, emphasizing division and understanding the concept of price per unit.

Discuss why it’s important to understand unit prices to make informed purchasing decisions and manage money wisely.

Include word problems that involve calculating unit prices, encouraging students to interpret the problem, perform calculations, and find solutions.

Learn with an example

➡️ A 5-pack of magnets costs ₹71.50.

₹ _______ per magnet

Find the unit price. Divide the total cost by the number of magnets.

₹71.50 ÷ 5 = ₹14.30

The unit price is ₹14.30 per magnet.

➡️ A 6-pack of scented candles costs ₹114.00.

₹ _______ per candle

Find the unit price. Divide the total cost by the number of candles.

₹114.00 ÷ 6 = ₹19.00

The unit price is ₹19.00 per candle.

  • 3-kilogram bag of gravel for ₹634.50
  • 5-kilogram bag of gravel for ₹1,058.00

Find each unit price. Divide the total cost by the number of kilograms.

₹634.50 ÷ 3 = ₹211.50
₹1,058.00 ÷ 5 = ₹211.60

The unit price for the 3-kilogram bag is lower than for the 5-kilogram bag. The 3-kilogram bag is the better buy.
