Looking for a purposeful way to help students tackle multi-digit subtraction with confidence and understanding?
This resource is designed to explicitly teach students the Constant Difference subtraction strategy, helping them regroup efficiently by shifting both numbers to make subtraction easier, all through meaningful word problems.
Rather than relying on traditional borrowing, students learn to find friendly numbers and apply the constant difference strategy with sensible reasoning and real-world contexts. Each problem encourages flexible thinking, strategic number sense and a deeper understanding of subtraction.
HOW YOU CAN USE THIS RESOURCE:
🌿 Teach and reinforce the constant difference strategy
🌿 Support students who struggle with standard regrouping
🌿 Small group or guided maths instruction
🌿 Whole class rotations or maths stations
🌿 Relief-teacher friendly lesson with minimal prep
WHAT'S INCLUDED:
𓅦 40x Word Problem Task Cards
𓅦 3x Levels of Number Complexity Differentiation
15x two-digit minus two-digit problems
10x three-digit minus two-digit problems
15x three-digit minus three-digit problems
𓅦 2x Levels of Strategy Support Differentiation
Empty strategy model cards
Partially filled strategy model cards
𓅦 PDF Version
2x Colour options - minimal colour and black & white
