Brief Description: Students will print out numbers in binary, base 8, base 10, and hexadecimal and use these to learn how to count in these base number systems. \ To Prepare: Students will need a computer that has the M3D software on it. We recommend one printer per every 2-5 students. The Micro or Micro+ 3D printer will need to be plugged into both the wall and the computer. Each printer will need to have a 250ft spool feeding into the external port. A spool holder is also recommended. If you need assistance with any of the above please see our guides at support.printm3d.com. Lesson Plan: 1\. Students will go online to: and download the base number models. 2\. Students will open the M3D Software on a computer, upload one of the models, and click print. 3\. Repeat with the other models. Until you have the following printed: Four of the following: 0, 1, 10, 11, \ Three of the following: 2, 3, 4, 5, 6, 7, 12, 13, 14, \ Two of the following: 8, 9, 15, 16, 17, 20, \ One each of the following: A, B, C, D, E, F, 18, 19, 21, 22, 23, 24, 100, 101, 110, 111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111, 10000, 10001, 10010, 10011, 10100. 4\. After they have all of the models, students should group them into the base 10 set, base 2 set, base 8 set, and hexadecimal set. 5\. Students should then arrange each set in order.
