Calculation Strategies

Ruth Merttens By Ruth Merttens

What is a calculation strategy? How can it help ensure consistency and pedagogical rigour throughout your school?

Hamilton's calculation strategy sets out methods of mental and written methods for addition, subtraction, multiplication and division from Year 1 through to Year 6. Articulated for each year group, these methods ensure consistency of teacher input and progression in pupil learning. They spell out the steps that children need to take to master these four operations. By ensuring that the language is pedagogically correct, the strategy helps teachers promote understanding in Key Stage 1, while laying the correct building blocks for understanding with greater sophistication in Key Stage 2.

Hamilton's addition/subtraction and multiplication/division calculation strategy documents make teaching easier for teachers and learning easier for pupils. The pairs of operations are presented as complementary functions that facilitate explanation and comprehension. Teachers and pupils both can easily see how one year builds on another. Teachers will have layout models that are clear and mathematically correct so that children do not build up misconceptions through their early years that they will need to unpick later.

Share these with your colleagues today! Hamilton even provide everything you need to run a staff meeting on 'Consistency in Models and Images' to give your school practical steps that can ensure that all your teachers are working towards the same methods using complementary and progressive language, models and images.
