3rd Grade Coding Project

Learning to Code with Paper Cups

The students' first project was learning how to code using paper cups.  Using special symbols, they wrote the code to stack a set of paper cups in a particular arrangement with their own "robotic" arms.

Programming the Ozobot

The Ozobot is a small robot with optical sensors on the bottom. The robot travels along any surface as long as it's not white. The students are creating maps using markers to make lines or paths. They are adding special codes to the paths. These codes are specific sequences of small rectangles in blue, red, green, and black that cause the robot to change its motion. The codes change the robot's speed, direction, and type of motion (zig-zag, spin, backwalk).

Ozobots can be programmed using Ozoblockly, a block-based programming editor. To use this programming editor, go to Ozoblockly.
