Build the computer literacy and problem solving skills students need to become innovators of the future. 

Introduce students to computer programming, or take their coding skills to the next level as they engage in fun activities and projects that enhance STEM learning outcomes. With an Hour of Code with Tynker, teachers can easily introduce the basics of computer programming in a fun and intuitive way.  Start with any of the six adventure puzzles, then students can apply what they’ve learned to create fun projects to share with others – multi-level and multi-player games, math patterns, interactive comics and greeting cards. 

No programming experience is required.  Use the resources provided to quickly plan a successful Hour of Code for your class. Students can access Candy Quest and Dragon Dash puzzles from this site.  The rest of the activities, plus a teacher's guide and answer keys, can be found at hourofcode.tynker.com.
