Year 1 subtraction – intelligent practice. Our recent ‘Addition – intelligent practice’ sets of worksheets have proved to be very popular and so we have moved forward the publication of a similar set of pages on subtraction. These are sets of four quick-fire mental questions which encourage children to think about the procedural operation of subtraction through connected calculations. The arrangement of the exercises makes children aware of the pattern and structure of maths, hence providing ‘intelligent practice’. Used extensively in the Far East this type of practice is seen as one of the reasons for the mathematical success children have in these countries.
