How to Code a Rollercoaster (Hardcover)

Pearl and her trusty rust-proof robot, Pascal, are enjoying a day out at the amusement park. Spinning teacups, ice cream, and of course: rollercoasters! Through the use of code, Pearl and Pascal can keep track of their ride tokens and calculate when the line is short enough to get a spot on the biggest ride of them all--the Python Coaster. Variables, if-then-else sequences, and a hunt for a secret hidden code make this a humorous, code-tastic day at the amusement park!
