Ideas, Thoughts, Things, & Awesome Things to Look Into
From the Elementary Computer Lab
I published another STEM lesson for lower elementary school on Thingiverse. This is a gravity fed coin sorter. I did this lesson a few years ago in the second grade, and the kids used poster board, rulers, and horribly dull school scissors. They improvised layering tape over the poorly cut holes, and a few of the kids got them to work. We taped them onto the wall and tried them out. This is the 3D printed version of the iterative process.
I like cooperative learning games. I have used something like this made out of laminated paper in the past, so I wanted to see how hard it was to design a prototype for the 3D printer. This is only a 3 inch prototype model because I had to scale it down to fit on my school's 3D printer. That's OK, because prototypes of the second or third try are not generally printed full-scale. As it is shown here, the plus and equals spots are too small to fit a pen or wood pencil, and the squares are too small for the unit squares aka ones blocks in the base ten block manipulatives that are everywhere in most elementary schools. So for demo purposes, we used beads.
Thingiverse is where my educational designs live. I began publishing this summer as part of the MakerBot Certifications Level 1 User and Level 2 Curriculum Creator. There exists a lot of manipulatives to make for the lower grades, but there are not many lessons that the kids themselves can create, and there are even fewer organized STEM lessons for this age group.
