Puzzle Chains for Juniors: 150 Puzzles for Grades 2–4

Start with a number. Follow the instructions. Work it out in your head.

Puzzle Chains for Juniors is 150 puzzle chains designed for young learners in Grades 2–4. Each puzzle starts with a small number and walks through 3–5 simple instructions—add, subtract, multiply or divide by 2—keeping kids thinking and building confidence.

Why Chains Work for Juniors

Unlike worksheets, chains keep learners engaged in one continuous problem. There's no "next worksheet" to rush through—just one chain, one answer, one success. They build working memory and mental maths fluency without pressure.

What's Included

• 3 Levels: Easy, Medium, and Hard
• 150 puzzles (50 per level), numbered straight through
• Numbers stay between 0 and 20—manageable and encouraging
• Simple operations only: add, subtract, multiply by 2, divide by 2
• Complete answer key at the back
• Print-ready PDF for classroom handouts

How to Use It

In class: Read the chain aloud once, learners keep the total in their heads, everyone writes the answer.

As homework: Print puzzles, learners follow the row across the page and write their answer in the shaded box.

As a warm-up: Five chains, five minutes. Builds focus before maths lessons.

The Levels

Easy: Starting numbers up to 15. Add up to 8, subtract up to 5, multiply or divide by 2. Every answer stays positive and under 20.

Medium: Starting numbers up to 15. Add up to 10, subtract up to 8. A bit more challenging, but still in the safe 0–20 range.

Hard: Starting numbers up to 18. Add up to 12, subtract up to 10. Trickier sequences, but still completely doable for Grade 4.
