Course Description: Teachers will learn the techniques of using a 3D printer. Once they learn how to use the printer, teachers can design curriculum that will instruct students to use the 3D printer to enhance curriculum. Teachers will create a playset of 3D figures based on a learning theme. Then they will write 7-10 lesson plans based on the playset and create a diorama. A journal will be kept by each student to record the experience and add writing to the curriculum
Teacher Competencies:  
  Domain 1:Planning and Preparation

Competencies
  1. 1e : Designing Coherent Instruction
Domain 3:Instruction

Competencies
  1. 3c : Engaging Students in Learning

3D Pizza

I was wondering what topic I should tackle this week, and I found this picture online.
Why wouldn't I want to learn how to 3D print a delicious pizza?   So I thought about what this particular pizza entails, and I thought of three main parts: crust, cheese, pepperoni, and mushrooms.

The crust remains the most elusive to me because I am still learning how to create perfect curved edges.   How would I take a shallow cylinder and turn it into believable pizza crust?  Well, I Googled "how to curve edges in sketchup."  You can see for yourself.

There is a way of using the Follow Me and the Rotate tool, but lo and behold, there are plugins to round the edges. I used the Artisan toolbar. You have to download the plugin to get the separate tools. I am going to post about that next, in my post called "Ruby Tuesday."

Here is my finished pizza crust. I'll add some mushrooms and cheese later.

Playing in th Sandbox

From the View > Toolbars menu, select the "Sandbox" toolbar. This toolbar allows you to create different landscapes. The "smoove" tool allows you to create a grid, then select different elevations. This can be used to teach landforms in Social Studies.

Math in 3D Printing

I was asked about applications in math for 3D printing during the Technology Summit, and I looked confused.  I looked confused because so much of the process of 3D printing has math embedded in it.
If you ever need to justify doing 3D printing to an administrator or a visiting guest, please feel free to show them a list of the mathematical principles used during 3D printing.

1. Shapes.  The shapes tool has rectangles, circles, and polygons of any size.
2. Measurement.  You have to set the dimensions of any line, shape, or push/pull.
3. Decimals and Fractions. You can input dimensions in whole numbers, decimals, or fractions.
4. Units of Measure.  Are you working in millimeters or inches?
5.Transformations. The rotation and scale tools help you transform your objects.
6. Points and Lines.
7. 3D Shapes.  Spheres, prisms of all polygons, cones, and cylinders.
8. Measuring Tools.  There are virtual tape measures and protractors to use.
9. Coordinate grids.  There is an X, Y, and Z axis. This is a real-world application of coordinate planes.  
10. Radius.  It is important that students understand that a radius is only half the diameter of a circle, so that printed circles will come out twice as large.

I was going to align the ten content areas to Common Core standards, but it is difficult because some concepts come up earlier than others. SO here are links for all the standards in measurement and data and geometry.
