Set B: Mid Difficulty - Who doesn’t love a  puzzle to challenge your thinking and mathematical skills? These attractive and challenging puzzles are a great introduction to algebra, without students realising they’re doing algebra.  They are great for developing logical thinking and elimination skills.  After students have learned basic operations, these puzzles are a great activity to be challenged. 
These puzzles are ideal for task cards, task centres and for use for gifted students and high achievers.
Each set includes 24  main puzzles (with a bonus 24 algebra puzzles), with varying levels of difficulty. 
Set A: Easy Level : Year 1—Year 3
Set B: Mid Level: Year 3—5
Set C: Hard Level: Year 4—Year 6 (and even challenges adults)
