Helping Kids with Coding For Dummies

by Camille McCue, Sarah Guthals

Overview

Help for grown-ups new to coding

Getting a jump on learning how coding makes technology work is essential to prepare kids for the future. Unfortunately, many parents, teachers, and mentors didn't learn the unique logic and language of coding in school. Helping Kids with Coding For Dummies comes to the rescue. It breaks beginning coding into easy-to-understand language so you can help a child with coding homework, supplement an existing coding curriculum, or have fun learning with your favorite kid.

The demand to have younger students learn coding has increased in recent years as the demand for trained coders has far exceeded the supply of coders. Luckily, this fun and accessible book makes it a snap to learn the skills necessary to help youngsters develop into proud, capable coders!

• Help with coding homework or enhance a coding curriculum
• Get familiar with coding logic and how to de-bug programs
• Complete small projects as you learn coding language
• Apply math skills to coding

If you’re a parent, teacher, or mentor eager to help 8 to 14 year olds learn to speak a coding language like a mini pro, this book makes it possible!
