Algorithms & Variables Worksheets
Free printable algorithms & variables worksheets with step-by-step answer keys. Every worksheet is uniquely generated so students never see the same problems twice. Topics covered range from single variable update: x = x op value at the easy level through to while-loop with termination condition at the advanced level.

Difficulty Levels
Beginner
- Concepts
- Single variable update: x = x op value
- Number Range
- operands: 1–20
- Steps
- 2 steps
- Example
- x = 7; x = x + 3. What is x?
Easy
- Concepts
- If-condition with one variable update

- x: 6–20, threshold varies
- Steps
- 2 steps
- Example
- x = 10; if x > 5: x = x − 3
Medium
- Concepts
- Loop with fixed iterations (for-loop trace)
- Number Range
- 4–6 iterations, ops: ×2, ×3, +3
- Steps
- 2 steps
- Example
- x = 1; repeat 5 times: x = x × 2
