Real World Math

“When are we ever going to use this math?”, “Where do you actually see this math in the world?”. As a math teacher these are the sayings you get from many middle school students. To take math from the pages of our textbook into their daily lives and give it application to careers the 7th grade students completed two projects. 

What better object to tie into math than an Apple iPhone. 7th grade honors math looked at the cost of an iPhone versus the cost of manufacturing to see how percent markup works and affects our lives. The results were quite shocking for some of them! They were fascinated to see how the percent markup has changed with different models of the iPhone. Conversations of supply and demand arose as many talked about waiting to buy newer models or the advancement of technology causing phones to last longer.

Meanwhile the 7th grade math classes looked at what goes into creating an enlarged image. Many of the students who have taken our art class elective have used grids to enlarge images but we looked at the math behind it all. Students got to choose a candy they wanted to enlarge. Using ratios of the candy wrapper to the size paper they would enlarge on they came up with their scale factor. From there they drew their grid and began the process of recreating proportional. They got to see how important it is to be precise and use rulers accurately. Students saw how computation mistakes would throw off their scale factor and the importance of having a strong number sense. It was one tastiest math project!
