Coding · Grade 1
First graders read block programs from top to bottom, put blocks in order to make a character say and do things, and predict what a program will do before running it. They check predictions by running programs and tracing again when a prediction is wrong.
Coding · Grade 1
First graders learn that an event, such as a click, a key press or the green flag, starts a script. They match events to scripts in programs with several scripts, predict what happens when events occur, and build their own event scripts for Olly.
Coding · Grade 1
First graders replace repeated blocks with repeat loops, trace programs with loops to predict what happens inside and after the loop, and use loops to do useful work for Bolt the robot: staircases, long snaking paths and rows of gems.
Coding · Grade 1
First graders learn that a character's state is what is true about it right now: its costume, position, direction and score. They trace programs to find the state at the end, and use forward and turn blocks, whose result depends on which way Bolt the robot is facing.
Coding · Grade 1
First graders make a trace of a program, recording Bolt's row, column and direction after each block. They compare traces with plans to find the first wrong block (which may come before the bump), and fix bugs in programs and loops, then test again.
Coding · Grade 1
First graders plan an interactive story (characters, a beginning, events and an ending), turn each event in the plan into a block script with loops where things repeat, and test the story with a partner, fixing any script that does not match the plan.
