Some awesome 2nd graders estimated with Holly Grove's DASH robots. Students had to estimate how long lines were on the ground then program the robots to see if their estimation was correct. Students coded the robots to drive forward or backward in increments of 10cm up to 100cm. The students had fun with tech and learned at the same time.
