Unplugged Coding Puzzles Book 2
Category: Education / Coding Activities
Your child thinks like a real programmer with a pencil: 80 screen-free puzzles on functions, nested loops, variables and events for grades 2-4, A4 and US Letter.
Watch your child think like a real programmer, with nothing more than a pencil. These unplugged coding puzzles for grades 2-4 teach functions, nested loops, variables and events, the ideas that turn simple steps into real programs. Fifteen quiet minutes at the table become real computer science, and your child learns to find the shortest code that works. This is Book 2 of our screen-free coding series: a 62-page printable book with 80 puzzles.
WHAT'S INCLUDED
• 1 ZIP download with 2 PDF books: A4 and US Letter (each laid out for its own paper size)
• 62 pages in each book, black and white and ink-friendly
• PRINT-GUIDE.pdf: which file to print, how to print, every symbol and coding word explained
• 80 puzzles: 4 new levels plus 10 Shortest Code challenges
• A worked example at the start of every level, plus "How to think" and "Watch out for" tips
• 36 cut-out code cards: FUNCTION, COUNTER, SET N, N = N + 1, WHILE, WHEN, REPEAT and arrows
• How to read the code page, a one-page reminder from Book 1 and a "Make your own puzzle" page
• Star tracker for all 80 puzzles, full answer key with every path drawn, Code Master certificate
THE LEVELS
• Level 5, Functions (puzzles 1-18): read a function, write the main code, build the function
• Level 6, Nested Loops (puzzles 19-36): read a loop inside a loop, find the missing numbers, find the missing arrows
• Level 7, Variables & Counters (puzzles 37-54): count the gears, open the lock when GEARS is high enough, set the variable N
• Level 8, Events & WHILE Loops (puzzles 55-70): event tiles with WHEN code, read and write WHILE loops
• Shortest Code challenges (puzzles 71-80): reach the star with the fewest REPEAT or WHILE cards
• Every puzzle has exactly one correct answer, checked by a computer program, and the answer key draws the path
PERFECT FOR
• Kids in grades 2 to 4 (about ages 7 to 10)
• Homeschool computer science and STEM
• Coding clubs, STEM centers and early finishers
• Kids who finished Book 1 and want the next level
• Quiet time, rainy days and travel without screens
HOW TO USE
• Go in order and read each level's worked example together first
• Use a coin or button as the dot and move it one square for each arrow
• Build the code with the cut-out cards before writing it on the page
• Two to four puzzles a day is plenty
• Check the answers together and color a star on the tracker
HOW TO PRINT
• Print at home or at a print shop on regular paper (80 to 100 gsm / 20 to 24 lb)
• Choose "Actual size" or "100%" in the print settings
• Print single-sided
• Card stock (160 to 250 gsm) or lamination works best for the code cards
• Pick the A4 file or the US Letter file to match your paper
