How to make your own blocks for CSDTs Unplugged

Step 1: Print out an image of the blocks: CSnap_Unplugged_printout_for_blocks.pdf.

Step 2: Cut out the paper image of each block with scissors.

Step 3: Cut blocks from plastic, or wood, or old extension cord--whatever is available. We found this square plastic pipe for electrical wiring in Kumasi: only 2 cedis for 10 feet! Cut lengths to match your paper blocks. Here we used a hacksaw with the pipe clamped in a vise. You can use flat paper strips but they are hard to hold and they slide around too much.

Step 4: Wrap clear postal tape around each block.

Step 5: Now continue to use CSDTs Unplugged.

How to use CSDTs Unplugged for adinkra computing.

Step 1: Demo adinkra computing using a computer or projector.

Step 2: Show how to lay out the blocks in panels, and provide whiteboard pens for writing in numbers.

Step 3: Challenge participants to create their own scripts using the "unplugged" blocks.

Step 4: Using small stamps and paper, check to see if someone else can create the patten using your script. As a final check, you can try it on a computer to see if it agrees. In this way a class with only one computer can support programming activities for many students.

How does the circle block work?

Right-click "edit" on the circle block and you can see how it works. You can use this knowledge to create your own custom block apps.

How does the log spiral block work?

Right-click "edit" on the log spiral block and you can see how it works. You can use this knowledge to create your own custom block shaps.

How does the line block work?

Right-click "edit" on the line block and you can see how it works. You can use this knowledge to create your own custom block shaps.
