How cool is this? The Grade 2/3’s took their Technology coding project curbside. The sidewalks have never looked so smart! Codes had to include 10 commands and a P1 or P2 (if the children wanted more challenge). P stands for Procedure. These commands are used to extract a common set of instructions or patterns from the main program – shortcuts to be employed once the long code (or spaghetti code) has been debugged and pattern have been identified.
