BIDMAS code breaker worksheets

Use the order of operations (BIDMAS) to reveal a secret maths joke. Make your students feel like a spy trying to crack a code in a fun and novel way for students to practice the order of operations. This product contains 3 different levels of difficulty: order of operations with multiplying, dividing, adding and subtracting - BIDMAS with brackets and the 4 operations - BIDMAS including indices. This will keep students really busy and help them to check their own working as they go. This is perfect for consolidation on the order of operations if you don’t want to use a traditional worksheet.

Each difficulty is colour coded (blue =easy, gold = medium, red = hard).

All the answers are included.

Suggestions for use:

  • Give to students to do by themselves (self differentiated or teacher chooses)
  • Give for homework
  • Use as a collaborative task - (pairs/3s work out a column each)
