“Ms. Forrest, what do systems of equations have to do with anything outside of our math class?” “When will I ever use this math?”. These are not uncommon questions in a middle school class. My typical response is, “Well students I am glad you asked!” To make our most recent chapter have meaning to our 8th graders I brought in something I know they like. It is not an unusual sight to see students show up to school with Starbucks cups and treats in the morning or walk into any teacher’s classroom and you are likely to find some coffee, usually a venti! So we combined our study of systems of linear equations and coffee to get some answers!
After our chapter on systems of linear equations we were curious to see if it would be better to purchase a Keurig machine and make your own coffee at home or stick with the convenience of a Starbucks trip. We took the real life Starbucks order of some of our middle school teachers and the cost of purchasing supplies at a grocery store to make that drink with a Keurig machine and started collecting data. Students calculated the cost of tax on the items and the machine and came up with a cost equation for both Starbucks and Keurig per cup of coffee. They tracked these relationships of a cup of coffee a day on a graph over the span of three years. Our results were confirmed using substitution and elimination.
Our data overwhelmingly showed that if we are looking at our coffee addiction from a financial standpoint Keurig is the way to go after about 3 months. However, most students agreed they love the menu options and convenience of a Starbucks coffee! We were able to take this strategy and see how it applies to business in the real world and comparison of cost effectiveness. Math really is EVERYWHERE!
Mrs. Nelson’s kindergarten class had SO much fun celebrating the 100th day of school! We have been learning and growing for 100 days and that called for a celebration. Our class has been working hard learning how to count to 100, write our numbers to 100, and challenging ourselves figuring out different ways to break 100 apart into equal groups. On the 100th Day we were able to use our skills to complete many fun 100 themed activities.
We made fun hats with 10 colorful strips and put 10 stickers on each strip. 100 stickers to wear all day.
We used number recognition and counting to stamp our way to 100 gumballs.
Each student brought a different food item to class. We made predictions about what type of food would be the heaviest, lightest, highest volume, and least volume. Each student counted out 100 pieces of their food by making 10 groups of 10. We weighed each item and them compared and contrasted. When we were finished we dumped the leftover (untouched) food into a giant bowl and created a delicious 100th day trail mix. Yum-yum…we enjoyed it for an afternoon snack.
As part of our weekly homework each student brought in 100 pieces of an item of their choice. We had a show and share and then displayed our eclectic groups of 100 on a collection board.
100 Sprinkles Smarter! We made fun cupcakes with 100 sprinkles on each. We counted out 10 sprinkles of 10 different colors.
Each student wrote a sentence and illustrated a picture about one thing they have learned in the first 100 days of kindergarten. We have learned so much and have grown academically, socially, and spiritually.
Thank you, Jesus, for a successful first 100 days of school!
“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!
