Looking for a purposeful way to help students tackle multi-digit addition and subtraction with confidence and understanding?
This resource is designed to explicitly teach students how to use bar models to represent and solve addition and subtraction problems, supporting them to visualise quantities, relationships, and unknowns through meaningful word problems.
Rather than relying on guesswork or disconnected procedures, students use bar models to represent partβpartβwhole and comparison relationships, helping them reason logically and choose efficient solution strategies. Each problem promotes flexible thinking, strong number sense, and a deeper conceptual understanding of addition and subtraction.
HOW YOU CAN USE THIS RESOURCE:
πΏ Explicitly teach and reinforce addition and subtraction using bar models
πΏ Support students to visualise number relationships in word problems
πΏ Small group or guided maths instruction
πΏ Whole class rotations or maths stations
πΏ Relief-teacher-friendly lessons with minimal prep
WHAT'S INCLUDED:
β 40x Word Problem Task Cards
β 4x Levels of Number Complexity Differentiation
10x two-digit plus two-digit problems
10x two-digit minus two-digit problems
10x three-digit plus three-digit problems
10x three-digit minus three-digit problems
β 2x Levels of Strategy Support Differentiation
