Ahhh summer is here!  Well not officially for a couple weeks, but the strawberries are ripe and fresh corn has been spotted in the stores. We saw this sign at a local farm stand:

I decided I’m going to wait for corn prices to come down a little before we buy some, and moved on to the next produce display. Wanda stayed back to study the sign for several minutes and finally asked “What does that mean?”  What is obvious to an adult can be such a puzzle to a 5-year-old. Upon closer inspection it hit me that this sign is a multi-faceted math learning tool for kids! Here was an opportunity to talk about money, fractions, adding, multiplication, rounding, and decimals, not to mention the concept of a “dozen”. Wow!

Step by step we read the prices and I explained what each line means. We talked about how a price that ends in “.99” should always be rounded up to the next dollar. She thought it was so weird that they don’t just sell it for 4 dollars or 7 dollars (I agree with Wanda).  I asked her to figure out if you pay more or less per ear of corn if you buy a dozen or a half dozen. This was a tough problem, so we worked it out together. Again, she thought it’s so weird that the more you buy the less you pay per piece of corn. Now there’s a great lesson in marketing as well as math!

This brief but educational exchange at the farm stand is the perfect example to support my “math is everywhere” mantra. I encourage you to look around next time you go out with your kids – whether it’s the farm stand, grocery store, gas station, the mall, or even a walk in the park. Can you find signs like the one we saw for corn? Can you see geometric patterns in the things you see in nature? Does your child know what all the different numbers at the gas station pump mean? These everyday activities are all opportunities for mini math discussions. Once you start to incorporate these math conversations in your day, you may soon find your child will do the same. So go ahead and call me corny, but I really believe every 5 minutes you spend doing math with your child really counts! π
