The Tynker Junior course collection comprising of 7 different adventures helps early readers develop foundational programming skills. To use these courses in your classroom, you must download the Tynker Junior app from the App Store. As they progress through the adventures, students learn about sequencing, parameters, events, loops, conditional logic, and nested loops that help to establish foundational coding skills. Then they apply their coding skills in free-form coding studios where they build their own projects with art, music and animation.

Tynker Junior is designed specifically for young children aged 5-7 — who have limited motor skills and are still developing hand-eye coordination — to learn to code using big blocks, pictures, voiceovers and tap-tap-tap interactions, without words or drag-and-drop or any other actions they may find too tedious or overwhelming.

Tynker Junior currently includes 5 adventure courses, 5 studio courses—with over 200 coding challenges:

Key stage 1
Pupils should be taught to:
  • use logical reasoning to predict the behaviour of simple programs
  • use technology safely and respectfully, keeping personal information private; identify where to go for help and support when they have concerns about content or contact on the internet or other online technologies
  • Class Presentations

    These student-facing slide presentations help educators seamlessly run Tynker lessons in a virtual or physical classroom setting. Each lesson has its own set of slides that introduce the big ideas, suggest unplugged activities, and include a section for each activity module. While running lesson slides, you can switch back and forth between the activity, the slides, answer keys and other lesson materials.
