Mental Subtraction Strategies – Year 2
Mental Subtraction Strategies – Year 2
Mental Subtraction Strategies – Year 2 gives teachers a coherent sequence for building flexible and efficient subtraction thinking.
The editable presentation introduces connected strategies and models when each one is useful. Students then apply the ideas through colour posters and reference material, two classroom games, differentiated bridge-through-ten practice, strategy-specific worksheets, mixed practice and quick exit tickets. A two-page school-garden assessment and five-level rubric support end-of-unit evidence gathering.
The resource balances explicit instruction with hands-on and independent practice. Colour displays and game boards suit whole-class modelling and maths rotations. Low-ink black-and-white recording pages, worksheets, exit tickets, assessment pages and rubric are ready for classroom printing. Ten matching answer pages reproduce the student pages and show answers in red.
