I did this cool activity with a grade 5 class today. We took about 10 minutes to draw a square and then improve our code by using a loop.
Then students were given the certificate below and they worked on their chromebooks to earn initials on each shape.
This activity requires only a few coding skills and then students get to “create” the other shapes. Lots of double fist pumps. Lots of mistakes and corrections. Lots of peer support. (NOTE: This activity is really a math lesson about interior angles).
If you want to see the value of computational thinking in action I recommend this activity. I am told it works well from grade 5-8. In 40 minutes no one was able to complete all of the shapes but some kids got close.
I got the activity from Steven Floyd.
