Coding Challenges STEM Activities for Beginners – 50 Hands-On Missions for Grades 6–8

Help your middle-schooler think like a computer scientist. Coding Challenges STEM Activities for Beginners packs 50 two-page missions into one printable 124-page PDF — each with a Look & STEM Idea page, a Try & Draw page, a mission goal and a materials list — for Grades 6–8.

What this book helps you do

Inside the book

• 50 two-page STEM missions for Grades 6–8 (ages 11–13)
• 7 sections, from Computational Thinking & Algorithms to Search, Sort & Design
• Look & STEM Idea and Try & Draw pages with a mission goal, time, difficulty and materials list
• Key computer science and coding words: Algorithm, Loop, Variable, Logic, Function and Debug
• For Grown-Ups notes and a Certificate of Discovery
• Printable 124-page PDF — Level D “Innovators” of the Mathfa STEM series

Topics covered

The book moves through seven sections: Computational Thinking & Algorithms (8 missions, from What Is an Algorithm? to Design an Everyday Algorithm), Sequence, Loops & Repetition (7 missions, from Sequence Matters to Loop Challenge: Efficient Patterns), Variables & Data Types (7 missions, from Variables Are Labeled Boxes to Variable Design Challenge), Conditionals & Boolean Logic (7 missions, from If This, Then That to Logic Design Challenge), Functions & Decomposition (7 missions, from What Is a Function? to Function Design Challenge), Debugging & Binary Data (7 missions, from Find the Bug to Debugging and Data Challenge) and Search, Sort & Design (7 missions, from Linear Search: Check Each One to Present a Coding Project). Every section opens with a mission plan, and the book ends with For Grown-Ups notes and a Certificate of Discovery for finishing all 50 missions.

Built for

Grade 6–8 students (ages 11–13); parents who want screen-light, purposeful STEM projects; teachers and homeschool families who need ready-made missions; and STEM clubs looking for investigations that end in something students can show.

Getting the most from it

Let students read the STEM idea and predict before they build or measure. Encourage them to record every result, even the surprising ones, and to explain what the evidence shows. Revisit a mission after finishing a section — improving a first design is where much of the learning happens.
