Brian P. Cleary once again is explaining things to young people in a way they will understand and better yet, will enjoy! This time Brian’s topic in his CATegorical series is dealing with computer coding.

Brian lets his readers know coding deals with commands in a special language, loops are repeated coded instructions, and conditionals are sets of rules dealing with “If this … then that will happen”.

“Loops and conditionals lend a big hand to code-writing pros of all ages, like YOU to write software, create fun, new games, or make your own apps or web pages!” (20-21)

Martin Goneau’s illustrations of cats personified learning about computers and coding make this a every fun and kid friendly visual learning experience. Brian P. Cleary and Martin Goneau make a great pair!

As an adult, I like page 22, the afterward, almost as much as the entire rest of the book put together. I hope students will not skip this page.
