Tracing shapes with Dash

{{ tags[0] }} Blockly Coding Experience Direction Based


In this activity, learners plan and build a sequence of movements to trace simple shapes.


  • Place a large sheet of paper on a hard and flat surface and tape its edges to the floor.
  • Tape a marker on each side of Dash.
  • Place one of the printed shapes on the large sheet and tape it to secure it in place.
  • Turn on Dash and start using the coding environment to make Dash trace the shape on the paper.


  • If you are doing this activity on a tabletop or an elevated surface, block the edges to prevent robots from falling.
  • If you don’t have access to a printer, you can draw or use masking tape to build a shape on the large sheet of paper.
  • Make sure the marker tips can touch the paper.
  • Traced lines may not be straight and accurate as markers may move in different directions.
