Coding · Kindergarten
Kindergartners learn to break a big job into small, numbered steps and to use first, next, then and last. They plan Bolt the robot's routes before building them, including routes that must collect gems before the charging pad counts.
Coding · Kindergarten
Kindergartners discover that the routines they follow every day (washing hands, tidying up, getting dressed) are algorithms. They decide which steps must stay in order and which can swap, and compare two algorithms for the same job to choose the clearer, complete, shorter one.
Coding · Kindergarten
Kindergartners learn the four arrow blocks, read short block programs by moving a finger one square per block, and build their own programs that steer Bolt the robot around hedges and over gems to the charging pad.
Coding · Kindergarten
Kindergartners find the part of a sequence that repeats, including groups such as clap-stomp or up-right, write it the short way (repeat 3 times: up, right), and use Bolt's repeat block to climb staircases and cross long gardens with only a few blocks.
Coding · Kindergarten
Kindergartners learn three kinds of bugs (missing, extra and wrong steps), find the first block that sends Bolt the wrong way by stepping through a program, and fix bugs and test again until the program works.
Coding · Kindergarten
Kindergartners learn that in an interactive story the reader's taps are events that make things happen. They plan a story with a beginning, a choice and an ending for each choice, and explain how it works using first, if you tap, then. They make story cards to share at home.
