Computational Thinking for Preschoolers: Debugging Activities


Producers from WGBH and Kentucky Educational Television and researchers from EDC have been collaborating on the research and development of brand-new computational thinking activities for preschoolers! These fun hands-on activities and apps (not yet published) were all created as part of a research project funded by the National Science Foundation called Integrating Computational Thinking into Mathematics Instruction in Rural and Urban Preschools.


Preschoolers can learn debugging and math through these fun activities:

Sound Shakers

Children fix sound shakers that don’t make sounds.

Monkey Dance
Children practice a two-step dance and identify mistakes in the teacher’s dance steps.

Monkey Bridge
Children fix a bridge that won’t stand up.

Colorful Caterpillars
Children debug clay caterpillars with colorful patterns.

Road Repair
Children use geometric shapes to fix holes in a road so a car can get across. Get a glimpse of the debugging app in development.


See how these activities are part of a larger computational thinking preschool curriculum in this Teacher Guide.
