How can you teach math in a way that is relatable to young children? One approach is to look for math lessons within their daily lives. Our lesson was a study in the economics of chewing gum. Target sells a pack of Trident gum for 97¢. The Target website doesn’t show the price for Trident gum, but Google Shopping Express reports a price of $1.12 per pack. (Interesting!)
Costco sells Trident gum for 73¢ per pack, but you need to shell out for a 10-count box. Out of curiosity, I stopped by a Safeway, which was selling it for $1.49 per pack. Yikes! That’s more than double the Costco price. But, the Safeway website has it currently at 99¢ per pack for a limited time with a Safeway Club card.
Shopping at Costco is so much easier because you don’t have to think whether you are grossly overpaying for an item.
