In CEP 811 this week, we were tasked with going to a thrift store, basement, or garage to find something to repurpose, with a MakeyMakey kit, into an educational tool. After failed attempts with a mandolin and guitar, that go unused in my house, I pulled out a socket wrench set from my garage. I was unable to create a meaningful set-up nor lesson idea with the instruments. The socket wrench set allowed me to incorporate the concepts of estimation, fractions, elimination, and measurement in both the metric and customary systems.
The idea of the activity is for students, given a socket dimension, to guess the correct socket. To make their selection, students will touch the socket wrench to the socket they believe is the correct size. If they are correct, they will here a sound signifying the correct answer. If they are incorrect, they will hear a sound signifying and incorrect answer. After making an incorrect selection, students will be informed of the size socket they have incorrectly selected. Using this information and the process of elimination students will work to continue guessing until they have selected the correct socket. The sockets are in both metric units and in customary units, thus providing practice with those measurement systems. As most of the customary sockets are less than an inch in width, students will need to be able to fluently compare fractions, such as 9/16, 3/8, and 1/2. Estimation and measurement are both standards incorporated into my 7th grade math curriculum. The process of elimination will also aid students in standardized testing.
I created this device by cutting holes fit to various size sockets that can be mixed with other sizes as the overall width of many sockets are equal while the bolts that they fit differ. After placing the sockets into the cardboard box that I used as a base, I connected all of the incorrect sockets with wires to the MakeyMakey in a way that they will all make the same noise for incorrect answers. The correct socket was connected to a different sound, signifying the correct solution. I used the “Drum Kit” sound board found here. When the MakeyMakey is connected to the computer it will link to the soundboard. Here is a video explaining the activity and device further.
In reference to the media above, the picture should give you an idea of what I was describing so you, the reader, had a better understanding of my description. The video is intended to give you a better overall picture of the device and how it may be used.
